The spindle is junk! The "blueing" of the metal shows it has lost its temper and is brittle. Replace it.

I remember those 4 piston MANUAL brakes. They were impossible to keep from squealing. The master cylinders of the time did not have a large enough reservoir to allow the fluid adequate cooling and after about 3 hard stops you had no brakes.:eek: Changing over to the standard later model GM style brake system was a common upgrade.

The Firebird also had the same system as an option. Those were the first GM cars to have disc brakes I am aware of. Chrysler had the disc brake option on their '66 line-up and Ford followed in '68. I seem to recall Ramblers having the disc option first but it could be just a hazy memory.

AMC did discs in '62 I believe.

I agree with using later A-body brakes.
After having a bad experience with the treadlevac drum brake system in the '57, I replaced everything forward of the rear brake line with a "modern" A-body setup - power assist, dual master cylinder, disc brakes, etc. they bolted to the '57 spindles (thank God for GM parts interchangeability) bur required i get rid of the original 14 in ch rims and go to at least 15s

I would get rid of the manual brakes, get a nice later A-body setup. It will be much, much safer and more pleasant to drive.

The spindle almost looks like it was broken off and rewelded then amaturishly smoothed out with a 2' long course file.

I loved that car. Dang.

Great GTO! That's going to be a nice car when fixed up.

BTW -I have a set of "670" heads that were rebuilt about 15 years ago and have been sitting in storage thinking I'll use them but now I like to get rid of. I also have an Offenhauser dual carb intake and a Isky cam for it.

Ford Thunderbird and Lincoln Continental used front disc brakes for the '65 model year.

I bet the wheel bearing repack was an every oil change routine considering they weighed like an elephant and greases were not very high spec back then.

Studebaker offered discs in '63 on the Avanti.

Well, actually they weighed more than two tons, but they had larger spindles and bearings to make up for it.

In the early days of disc brakes, there did indeed become a need for wheel bearing grease that could deal with higher temperatures. In the fifties and sixties they sold wheel bearing grease in a can. When disc brakes came along, folks started using the best moly grease they could find and just squirt it out of the grease gun.

In the mid sixties, the conical wheel bearing packer fixtures started to become popular. It was a match made in heaven since people were starting to use gun grease on wheel bearings.

Zulfiqar 05-14-2013 03:30 PM

I saw a can of grease recently - it said disc brake wheel bearing grease and all other bits eroded off - the manufacture was quaker state. It was very very dark brown and had what I can call ground up rope (like hemp).

more sticky than slick. - Was that sort used on those cars?

Air&Road 05-14-2013 03:35 PM

Yes, there was disc brake grease available, but I never saw an open can that I can remember, because we used the good, black moly gun grease with them.

I believe that post referenced the t birds and lincolns...some of the lincolns I believe nudged up near 5000#.

catmandoo,

I see where you got confused. My response was to a quote from Zulfigar whose response was to a quote from P.C. talking about Lincolns and Thunderbirds of the era. My weight comment was with respect to Lincolns and Thunderbirds.
