DV8 Posted April 10, 2019 Share Posted April 10, 2019 So my brakes are requiring a lot more ‘knee grease’ than usual to come to a complete stop. Still stopping just fine though. I’ve been hearing a hiss from them for quite some time. I’m assuming rebuilding the power break booster will bring it back to normal. My question is does anyone know of a source for reliable parts to rebuild the booster? I can find a master cylinder rebuild kit which I will also rebuild in the process but finding the right kit for the booster seems limited. One or two items on Ebay but all old stock. I’m dealing with the Delco Moraine power brake system on a ‘65 Riviera. Link to comment Share on other sites More sharing options...
telriv Posted April 10, 2019 Share Posted April 10, 2019 Send it to "Booster Dewey" in Oregon. It will be rebuilt with NEW nec. parts & work like new when re-installed. Not really worth the time & trouble to locate & try & rebuild it yourself with marginal (because of time & age) NOS parts. Just my thoughts.

RivNut Posted April 10, 2019 Share Posted April 10, 2019 Contact "Booster Dewey" at the Power Brake Booster Exchange fot the parts you're seeking. Google his name for contact info. He's old school, no texts, no email, but he's really good. Call him. 2 Link to comment Share on other sites More sharing options...

KongaMan Posted April 10, 2019 Share Posted April 10, 2019 If you're going to rebuild your master anyway, you might consider replacing it with a dual cylinder. Installing the new line might not take appreciably longer than doing the rebuild, and you'll end up with a safer system. IMHO, NOS rubber parts are a crap shoot anyway when they're decades old. You might end up back where you started. But before you do anything, you might check the obvious (like the check valve, etc.) to make sure there isn't a simple fix.

Bloo Posted April 10, 2019 Share Posted April 10, 2019 I don't think Booster Dewey sells parts, but I would start there anyway. There is another company called Harmon Classic Brake that stocks basically everything in the way of parts. Sometimes sending it in to Booster Dewey is almost as cheap. I recently had a Midland (Ford) booster rebuilt at Booster Dewey's (by Booster Steve, actually), and the work was top notch. It has been on the road for a few months now. It looks nice, and no issues. Link to comment Share on other sites More sharing options...
JZRIV Posted April 10, 2019 Share Posted April 10, 2019 (edited) I exhausted every resource I could think of trying to find rebuild parts for a booster because I like doing things myself and avoiding the hassle and cost of packing and shipping and risk of a lost package, and like Tom said, Booster Dewey has to be getting the parts somewhere. I've had boosters apart and they aren't rocket science. I did find it odd that with so many GM boosters across model lineup that are likely the same internals why no aftermarket supplier offers rebuild kits. I thought it was just a matter of not looking hard enough to find one but not so. I contacted Dewey and ask about sending me parts and he would not nor would he reveal where to get them and really why would he because that would mean lost business. I checked with multiple other suppliers such as those for Chevy and Corvette parts as well and came up empty. I finally sent my booster to Dewey.

Not selling the parts reminds me of an equation: Booster Dewey rebuilt my brake booster does not = I rebuilt my booster with Booster Dewey parts. But I have heard that kind of thing when stuff doesn't work out. Link to comment Share on other sites More sharing options...

RivNut Posted April 10, 2019 Share Posted April 10, 2019 When I converted my '64 to a dual reservoir master cylinder, I called Dewey and talked to him about O-rings. He told me because I had a '64, I could just use what I had; if it had been a '63, he told me that I'd have to source a different O-ring. Apparently there are some subtle differences between the years. Link to comment Share on other sites More sharing options...

telriv Posted April 10, 2019 Share Posted April 10, 2019 For the cost that Booster Dewey charges, some are $150.00, unless you like experimenting given your expertise is it really worth your time??? Then after you do it & it doesn't work correctly you have to start over & need more parts??? I took mine apart for other reasons & I was lucky it worked like it should. IF it didn't I would have sent it to Booster Dewey. Tom T. 3 Link to comment Share on other sites More sharing options...
RivNut Posted April 10, 2019 Share Posted April 10, 2019 I guess this is as good of a place to post this as anywhere else. Words of wisdom that came from my father, a full time Buick mechanic in Hutchinson, KS "Cheap labor isn't skilled, and skilled labor isn't cheap!" Pay the guy who knows what he's doing to do it. DIY'ing is great if you're good at it and have done it before, AND THERE'S NOTHING TO LOSE. Otherwise, leave it to a professional. I'll only mess with something as long as electricity, fuel, or vacuum isn't involved in the equation. I have neither the tools, NOR the background to waste the time and effort. Reminds me of my brother when he built a log home. He spent way too much time trying to save money by doing things himself. He learned to late that the per diem interest on his construction loan cost him more than what he would have had to pay a crew of professionals to do the work. Plus maybe five years later, the fireplace would not have fallen away from the house. 1 Link to comment Share on other sites More sharing options...
Bloo Posted April 10, 2019 Share Posted April 10, 2019 (edited) Nothing wrong with wanting to do it yourself. There is an old saying that if you want something done right you have to do it yourself. It is very true of most jobs on old cars... however... In my case it was going to cost almost as much for the kit (or even just the individual parts that were obviously bad). About $15 difference as I recall. I like to do things myself, and also didn't want to wait, but it needed stripping and repainting too as the lower part had been stripped by brake fluid. I decided to send it off. I was very happy with the result, and it didn't cost any more either (after adding in rattle cans). I am not going to rule out rebuilding my own in the future, but this went so well I probably won't. In any case, don't screw around with NOS parts. Rubber parts are what fail. Harmon Classic Brake has new booster parts for almost anything. Seafoam65 mentioned that Fusicks have Riviera kits. There are several reasons you don't normally see kits. Although it appears the early Riviera uses the same booster in every car for a given year, that is not true of most American cars. Often there are 3 different brands. Often there are mid-year changes. Also, the Midland (Ford) booster I sent off comes apart with a band clamp. Most boosters are twist-lock affairs that are crimped together after assembly. It would be very difficult to get a crimped one apart and back together for a restoration without visible damage. Dewey's turnaround was quick and the booster works great. You can have your original unit rebuilt if you want. I would do it again. Edited April 10, 2019 by Bloo (see edit history) Link to comment Share on other sites More sharing options...
DV8 Posted April 11, 2019 Author Share Posted April 11, 2019 Thanks, everyone for sharing your experiences and resources. I now have many more options to explore than I had just yesterday. I’m curious if anyone has any experience with a company called Prior Brake Products rebuilding their booster unit. It’s just one other option I’m looking into and it seems to be the most economical one. Link to comment Share on other sites More sharing options...
RivNut Posted April 11, 2019 Share Posted April 11, 2019 You're more than liable to get what you pay for. Remember, these are your brakes. They keep you from going through an intersection and T-boning a car with a toddler in it, or not being able to stop at a train crossing, or running under the back of a semi. Your life depends on them; as well as the lives of your loved ones in your car. I cannot imagine trying to tell someone's family that their loved one is dead because I wanted to save a couple of bucks on something I had no business working on in the first place. Just my opinion. 2 Link to comment Share on other sites More sharing options...
Buffalowed Bill Posted April 13, 2019 Share Posted April 13, 2019 I've used Booster Dewey for booster work in the past. Several years ago I called to ask about a rebuild on the Hydrovac, as used on my 1955 Studebaker Speedster, and he would not touch it. I was not satisfied with his excuses for not wanting to service the unit. There are other rebuilders out there, so I have taken my business elsewhere.

KongaMan Posted April 14, 2019 Share Posted April 14, 2019 Yeah, I turned down some work the other day from a guy who wanted some custom parts, with ever changing specs.

rocky5517 Posted April 15, 2019 Share Posted April 15, 2019 If you send your booster to Dewey ( which I think you should) ask him about re-finishing it with the proper finish. My 67 was originally a gold cad/ I let him re-finish the booster. the cap for the reservior, AND the hood latch!! He suggested I throw in the hood latch, and I was really happy. 1 Link to comment Share on other sites More sharing options...
Buffalowed Bill Posted April 15, 2019 Share Posted April 15, 2019 Certainly it's "his business his choice," and if he can afford to turn down my business, I have no choice to take mine elsewhere. He did an acceptable job rebuilding the booster for my 1963 Riviera, and since this is a Riviera forum I guess that it should stop here. I was just trying to present a no frills comment on my experiences, for the purpose of providing some balance. There may be some folks out there that own Riviers, that also own a 50's Cadillac or other GM product that used a Hydrovac. They might like to know Dewey's limitations.

RivNut Posted April 15, 2019 Share Posted April 15, 2019 I'm sure the next guy who needs a hydro boost repaired will contact you for a recommendation. Kind of like me going to a proctologist for a toothache. Hopefully he'll turn me down and suggest I find some with the proper tools and background to look at my tooth.

jframe Posted April 15, 2019 Share Posted April 15, 2019 All this talk about rebuilding them yourself. I may be wrong, but to my understanding, rebuilding a booster used to take some specialized tools, I thought. Not done very often today. As a dealership parts manager, I realize that we should rename "parts department" to "assembly department" since almost EVERYTHING today has to come in an assembly.

Bloo Posted April 15, 2019 Share Posted April 15, 2019 It depends on the booster. The one I spoke of had a removable band. There wasn't anything in there I couldn't handle. I think the control valve would have required a modified snap ring pliers or something. Many are crimped. There are multiple how-tos on Youtube. Typically they are cutting and bending things to release it, and then you need a long lever (that you would have to make) to twist it apart. I have no confidence that I could do this myself without leaving visible damage. I probably wouldn't do it when there are better alternatives. New replacement boosters for American cars today are made in other countries, and there are no repair parts available for them (ask any rebuilder about that). Using one would likely leave you stuck with no options for repair at some point in the future. Mailing things out for rebuild over the years has been for me fraught with disaster. I have had much better results doing things myself. More often than not, using someone else costs a lot and the results are unsatisfactory. The experience with "Booster Dewey", (where "Booster Steve" actually did the rebuilding), went very well. I would use them again without reservation.

That seems to be part of the plan. We've renamed mechanics to technicians. That happened when the guys in the service department swapped their toolboxes for laptops. Robots to change out the assemblies won't be too far down the road. I guess we could call them Robotechs. 1 Link to comment Share on other sites More sharing options...
DV8 Posted April 19, 2019 Author Share Posted April 19, 2019 Update: Had a few conversations with George at Harmon Classic Brakes which seems to be the source for all the rebuild kits that everyone uses. A few bits of good information that he gave me: ’65 is what he referred to as a “crossover year.” There was a strike at GM at the time and Buick was putting whatever boosters they had just to get them out of the factory which is the reason some ‘65’s have a Delco Moraine, some have a Bendix or, like mine you have a dealer installed Bendix Master Vac 9”. After removing the booster, I began disassembling it according to the shop manual following the instructions for the Delco Moraine unit (because, best I could tell, that’s what I thought I was dealing with). It quickly became apparent that I am not equipped with tools with enough torque to pop the housing open. I snapped a few photos and sent them off to George and he advised me that I, in fact, had the dealer installed Bendix Master Vac unit and that that particular model is near impossible to crack open without specialty tools. Also that, even if I did get it open without damaging it, there’s a good chance of the spring damaging me. I promptly heeded his advice, boxed it up and shipped it off to be rebuilt which is where I’m presently at. They do have all the rebuild kits at Harmon that come with a lot of good information. Their prices and expertise seem to be on par with Booster Dewey. 2 Link to comment Share on other sites More sharing options...

DV8 Posted April 26, 2019 Author Share Posted April 26, 2019 I really couldn’t answer that with any certainty but the way I understood it was that some of the the cars may have left the factory with manual brakes (which was the same master cylinder just without a booster) and if a buyer chose a power brake option (because I believe it was in fact an option back then like cruise control or deluxe upholstery) that the dealer would install the booster.

ALL Rivieras from the first generation on came with Power Brakes, Automatic Transmission, and Power Steering as standard equipment. Tilt was standard equipment in '65. For many years, true dual exhausts and "high performance" engines were standard (higher compression and four barrel carb with the dual exhaust.) 1 Link to comment Share on other sites More sharing options...
DV8 Posted April 26, 2019 Author Share Posted April 26, 2019 There’s a chapter in the shop manual for ‘Manual Brakes’ which is one of the things that lead me to that conclusion but I suppose that must have been for other models for which power brakes were an option.

RivNut Posted April 26, 2019 Share Posted April 26, 2019 Oh yeah. The basic Lesabre was covered by the same chassis manual. Two barrel, single exhaust, low compression, manual transmission, non power brakes and steering. If you're really interested, I'll post a pictue of the window sticker for my 63. It lists all the items that were standard on the Riviera that were considered options on other models. Link to comment Share on other sites More sharing options...
