sebastienbuick Posted May 23, 2017 Share Posted May 23, 2017 Hello, I have been looking for more than 3 years one or two brake disc for buick electra 225 of 1969. Apparently it's very rare found If someone has not one to sell even rusty it interests me.thank you Link to comment Share on other sites More sharing options...

joe_padavano Posted May 23, 2017 Share Posted May 23, 2017 Replacement brake rotors for the 1967-1970 Olds/Buick full size cars are NOT readily available. There are so few of these cars surviving that no manufacturer currently makes replacement parts. Impala brake parts do NOT fit. If you find a listing at a site like Summit or Carid, it's wrong. You MIGHT find the out-of-production replacement rotors (Bendix, Raybestos, EIS, etc) on ebay or from other specialty sources, but expect to pay stupid money if you do. There are no readily available modern rotors that fit without extensive machine work. Scarebird makes a conversion kit that uses Ford rear rotors. I have no first-hand experience with this kit and cannot comment on fitment or quality. Link to comment Share on other sites More sharing options...

I don't know what the difference is, but Hollander and the factory parts books both show them as not interchanging. By the way, I've tried to adapt the comparable rotors from a mid-1970s Chevy half ton. They are different. The bearings are the same and the newer rotors will fit on the spindles, but the backside of the rotor hits the lower control arm. Apparently the friction surface is further inboard on those rotors. They might be able to be made to work with some light machining to clear the control arm. 1 Link to comment Share on other sites More sharing options...

JohnD1956 Posted June 3, 2017 Share Posted June 3, 2017 The 67-9 full sized Buick used 4 piston caliper disc brakes ( Bendix I think) , and that changed in 1970. I believe the rotors are 11 inch in diameter. When I had my 69 Electra I thought one may get lucky IF a front rotor can be disassembled from it's hub. I know drums can be pressed on and off of the hubs. I do not know if discs can be pressed on or off. But IF they can be, then there is an outside chance a Corvette 11" Rotor from the same period can be used. This comes with two warnings: 1- I do not know for a fact that the early Corvette disc is the same diameter 2- I do not know for a fact that the early Corvettes used 15" rims and the same bolt pattern. While I do not know this for a fact, I do believe both the diameter and the bolt pattern are the same as the Buick. I believe the hub is different but I don't know if that's true either. Sorry to interject so many variables. But when I sold that car I stopped investigating it. Link to comment Share on other sites More sharing options...

joe_padavano Posted June 3, 2017 Share Posted June 3, 2017 (edited) Let's correct some mis-information in the last few posts. The full size cars used rotors that were 11.875" in diameter and 1.25" thick. Most people call these 12" rotors as opposed to the 11" rotors (actually 10.75") used on the mid-size cars. The four piston calipers were used by Buick for the 1967-69 model years, as noted. FYI, this is different from the full size Olds disc brakes - Olds went to the single piston caliper with the 1969 model year. Rotors are slightly different from the four piston to single piston applications. The rotors for the four piston brakes should all be two piece. The single piston brakes could have used either two piece or one piece rotors. The Corvette rotors are 11.75" diameter and 1.25" thick. Unfortunately, the Buick uses the 5 x 5" wheel lug pattern of the full size cars and the Corvette uses the 5 x 4.75" pattern of the mid-size cars. Even then a good machine shop could weld up the old holes and machine new ones, but there are several other critical dimensions that must be considered, as shown in this drawing: I have no idea if the height or offset of the Corvette rotor are even close to correct when fitted to a Buick hub. This was the problem when I tried fitting the Chevy truck rotors I mentioned in Post #11. Those rotors fit right on the spindles and have the correct 5 x 5" bolt pattern, but they have too much offset. The inboard face of the rotor rubbed on the lower control arm. You will note, by the way, that I didn't even have splash shields in place in this photo. These rotors would certainly have rubbed on the splash shields. As for Inline Tube, they sell a LOT of parts for the mid-size Buick A-body cars. They sell very little for the full size cars other than pre-bent brake hard lines. As I pointed out in Post #5, NO ONE sells new replacement rotors for the 1967-70 Olds/Buick full size cars. I would be thrilled for someone to prove me wrong here, but I'm still waiting for that.

JZRIV Posted June 5, 2017 Share Posted June 5, 2017 (edited) Joe is exactly right. I've seen a number of 67-69 Riviera owners over the years be stuck trying to find rotors. If I had a car that needed them, I'd convert to original aluminum finned drums and be done with it and eliminate service problems. I had a low mile 67 Riv with the front disc option and honestly I couldn't tell the difference between that and my other 67 (under normal driving) with a properly setup and maintained original 4 wheel drum system.

sebastienbuick Posted June 5, 2017 Author Share Posted June 5, 2017 Hello everyone and thank you for your answers Yes indeed they are bendix, I have to contact some old car crashes in america and none of these breaks have a rotor.I have made several website, ....Living in France, there are far fewer pieces of American cars, one finds more often for the best known cars (mustang, camaro, ...) but not for mine.I look on craiglist but this site is so big that I can not see any ads.Here are some pictures of my rotor out of usethank you Link to comment Share on other sites More sharing options...
joe_padavano Posted June 5, 2017 Share Posted June 5, 2017 I'm looking at some rotors from Wilwood racing. They sell a wide variety of disk brake hardware, primarily for racing applications. They do have separate rotors and hats that might be able to be configured to fit your car. They won't look stock, but should be functional. I'm investigating these for my similar 1967 Oldsmobile. I need a few more dimensions. Can you measure from the wheel mounting surface to the front (outboard) face of the rotor? Also, can you provide the outside diameter of the wheel mounting surface? Thanks. Link to comment Share on other sites More sharing options...

joe_padavano Posted June 6, 2017 Share Posted June 6, 2017 I'll say it again. NO ONE makes replacement rotors for these cars. Any ad that says the rotors also fit a Cutlass, Skylark, or any Chevy should set off very loud alarm bells. Those are NOT the correct parts. The 11" diameter should also be a warning that they are not correct. Those are A-body rotors that are available everywhere. 2 Link to comment Share on other sites More sharing options...
mike6024 Posted June 6, 2017 Share Posted June 6, 2017 What year range would be compatible with the '69 Electra? My mother happened to have a '69 Electra when I was young. Wrecking yards have a computer-connected nationwide inventory system, so if you walk into a wrecker and ask for a part, they can check on the computer if any other yards in the country have that make and model. http://www.autowreckerssantarosa.com/ Link to comment Share on other sites More sharing options...

Gee, you might think that EVERYBODY who owns one of these cars is looking for them... and has been for the last decade, by the way. The supply of N.O.S. parts is all but dried up. Used parts are only available if they are too thin to turn. We've all been calling the wrecking yards, combing the swap meets, working the networks, participating in the clubs, etc, etc. On the rare occasion that a usable rotor does come up, it is snapped up in no time, and the buyer ends up paying stupid money for it. 1 Link to comment Share on other sites More sharing options...
lump Posted June 7, 2017 Share Posted June 7, 2017 There are a number of companies which offer Disc Brake Conversion kits, intended to convert cars which came with front drum brakes over to disc brakes. Nearly all of these kits use aftermarket rotors, calipers, and spindles, I'm thinking of companies like THE RIGHT STUFF DETAILING, and the STAINLESS STEEL BRAKES CORP, etc. You might contact them and find out if they offer a kit for 1969 Buick full size cars. If they do, you may be able to "convert" from stock original disc brake system to an aftermarket system, for which replacement parts are readily available. 1 Link to comment Share on other sites More sharing options...
lump Posted June 7, 2017 Share Posted June 7, 2017 Also, years ago I heard of folks using "spray welding" techniques to build up surface thickness on rare old flywheels, etc, and then machining them back to correct tolerances.

As I pointed out waaay back in post #5, Scarebird makes a conversion kit for these cars. The kit is intended to be used on original DRUM BRAKE cars, not a factory disc car - the spindles are different. Also, the Scarebird kit uses thinner Ford REAR rotors on the front, requiring machining of a DRUM brake hub. The thinner rotor also requires the use of matching calipers - so the OP's original calipers can't be used. Link to comment Share on other sites More sharing options...

I hope I am wrong. Flame spray of powdered metal is a technique used to repair worn surfaces such as crank journals on large engine crankshafts. Of course, those are hydrostatic bearings, and obviously the oil film plays a big part in protecting the flame sprayed material. I don't know how that material would hold up under dry brake rotor use. 20-30 years ago there was a vendor advertising exactly this service for unavailable brake parts at the Pomona swap meet. I have not heard from or seen this vendor since, which probably does not bode well for the success of the process on brake parts. Link to comment Share on other sites More sharing options...
joe_padavano Posted June 7, 2017 Share Posted June 7, 2017 (edited) 2 hours ago, sebastienbuick said: Here are some photos of different measure Perfect! Thanks. Wilwood sells separate rotors and bolt-on hats in various sizes. Rotor P/N 160-0483 is the same 11.75" diameter and 1.25" thickness as your originals, for about $39. The hats look like this and typically slide over the hub and wheel studs from the outside. The rotors bolt to the hats to make an assembly. You could remove your old rotors and get a hat that has the correct offset to slip over the front of the hubs. This would move your wheels 0.25" outboard. Alternately, Wilwood sells undrilled hats that you could have machined to fit on the backside of your hub, like the original rotors. From your rough measurements, it looks like you'd need about 1.69" of offset. They make a hat that is 1.71" offset (P/N 171-3754). I may try this for my own application. Note that your fixed four piston calipers are very sensitive to rotor alignment inside the caliper, so some shimming may be required. The sliding single piston calipers are much more forgiving as to small variations in rotor offset.
