Lancemb's 57 Roadmaster Facelift


Recommended Posts

At the end of last summer the master cylinder started to fail.  I finally got the rebuilt one in today, and was able to pull it out and clean up the white walls on the new tires riding on the fresh Kelsey Hayes wheels!  It had a set on it when I pulled it out of its 30+ year hibernation, so this is how it looked in the 1970's when it was formerly on the road!

Sure looks great Lance! :)


How is the 2 door coming along?

It will be fantastic to see it done and sitting / showing the two together!! B)

Thank you!  Coupe is coming along and I'll post an update on that in a couple weeks.  Had to take a break from it to get Big Blue back on the road though!  Plus I needed the wheels on this car to use as rollers on the coupe since I was tired of filling the crusty tires that were on it with air.

I took her out this morning to air up the tires and fill the tank and was surprised by a most unusual story by a guy who was filling his fuel tanker.


Most people don't know exactly what this car is at first, but this guy knew right away it was a 57 Roadmaster.  He went on to explain that he was born in the back seat of a black and red 57 Roadmaster in 1961!  I guess his parents were en route to the hospital and he just couldn't wait, so by the time they got to the hospital he was born right there in the back of the Buick!


He said he is a car guy, but unbelievably, he is into Chevelles and not Buicks!

I FINALLY started taking Big Blue apart for a transmission transplant.  It will be a couple weeks at least before I have a whole day to dedicate, so I started since I had a couple solid hours.  It will take more than a day of work anyway, as I will do the u-joint while I'm at it and of course replace the worn rubber mounts.


I got the rear end loose and dropped down enough to let tension off the springs.  I'll probably do a little at a time over the coming weeks and see how far I get.


After that I'm going to check all the brakes.  I am pretty sure I'll be replacing the front drums with ones I just had relined, but not sure of condition of the rest.

Well, I finally got around to getting the rear end out from under car, and also got the transmission out.





The trans pad came apart in shreds!  The thrust pad rubber is still intact, but pretty worn.  Both will be replaced.




I did a light clean up on the axle and torque tube and it kinda looks worse with the nice fluffy cake gone and all the surface rust exposed.  However, it occurred to me that I have an extra torque tube (both pieces) already powder coated black so I might paint the axle and utilize them. 


I also confirmed that the rear u-joint is trashed, which I suspected and was reason I haven't been driving the car much. 


The needle bearings and/or parts of the cup from one side have been deposited inside the rear torque tube as little shavings.

Some more progress this week, but I also bit more off, so it will take longer to chew.  I was originally going to just replace the U-joint and trans, then go through brakes afterwards.  Then I saw how crusty the axle looked after cleaning it up so I decided to paint it and use some powder-coated backing plates and torque tubes I already had.  Then I thought, if I am going to do that I'll have to have the brake lines off so I may as well replace those with stainless.


So, I have more parts on order.  The brakes looked great in back, so I just cleaned everything up and put them back together and adjusted them.  It's not perfect, but a big improvement I think.




The rear short driveshaft went through a few changes in 57, as the grease on the rear splines would work its way out, and the splines would then strip out.  Late in the year grease fittings started to be installed.  This car never had one, so I opted to add it.  This meant I had to add a hole in the correct place in the rear torque tube for access to the fitting.  In addition, I added a hole further up for access to grease the new U-joint; I will plug these.




I have a couple of the original special grease fittings, and was going to install one, but then I decided to look at the 2 extra shafts I have.  I actually have 3 different design iterations.  The one in the car was the first pictured, which used a retainer with a felt seal to keep the grease in.  The one in the middle uses no retainer and seal, but has the fitting in back, but was still prone to leak grease.  The third is the later design, which is not prone to leaking grease in back and also already has a grease fitting.   I opted to utilize and put on this one, of an improved design.  It is shown here after the new u- joint is installed.




I will expound on the short shafts more at a later time, and maybe even do a writeup for the Bugle.  I think there are a lot of 57 Buicks out there with ticking time bombs in these shafts.  I was lucky, since my car has under 60k miles, that I got to mine just in time; it was dry and starting to shine up.

So, should I see a grease fitting on my 57? Towards the pumpkin?

You will want to see a rubber plug in a 13/16 access hole about 8" from the back of the rear torque tube, behind which you'll be able to access a grease fitting when the shaft is oriented correctly.
