I upgraded my front brakes, and these have been sitting in my garage a few years. Are these original rotors and calipers? They were shot and had to come off my car a few years back in order to pass state inspection. I understand there were optional Buick front discs at the time? Or would these have been fitted as stock? Or are they some ancient aftermarket upgrade? Worth eBaying to the concours crowd? Or just boat anchors now. What about the trim bits? School me ;-)
I’m fairly certain those are quite rare so I wouldn’t toss them. I just recall the calipers costing a pretty penny to replace so I’m sure someone would want them if in working or rebuildable shape.
Check to see if there is a casting # on the calipers. A body GM ones always did. Not sure about upeer series though.
2 pistons calipers were 69 and earlier. rotors look to seal into backing plates also. casting numbers for calipers would be a big help.
GSJohnny1, Full size Buick cars had 4 piston calipers '67-8 & 9 & I think/believe that holds true for the A-Body cars as well. The rotors seal on the spindle just like MOST other cars. Tom T.
There are no visible casting numbers on either 4-piston caliper. But cast into each outer face, bleed nipple side, is the letter "D'' at the top. Lower down, I can make out the letters ''OTH'' on each outer, and looks like there would have originally been more letters on each caliper but worn/ground off. possibly the words ''OTHER SIDE''? Or a manufacturer name? Does this give any clues? I'm really just trying to find out if these are worth passing on...or dumping.
Those are the old style 2 piece hub and rotor. What wheel bolt pattern ? What is rotor diameter ? The early vette rotor iirc is a little bigger than the a-body rotor but look similar. Those 2 piece setups still bring money for restorations. Your hub may have different bearing ? On a-body there is a 1969 only backing plate specific to the 2 piece rotor. Hard to find. The pic of caliper on Rock auto says "other patents pending" so rest of letters are missing
Thanks very much. So it's the original hub/rotor and Bendix calipers. RockAuto pic says it all. Were these fitted to all GM B-bodies in 1968 i.e. Impala?
Those are Buick specific calliper and rotors, extremely rare and highly collectable. Big car only 5 on 5 pattern. I believe gsfred on the board has replacement pads.....do not throw this setup away. I just went through this with my disc brake wildcat. Gord
Not sure but it seems the big cars within GM were doing there own thing and had their own ideas with regard to suspension, braking and even rear ends. I really doubt any other manufacturers would be sharing parts with GM if they weren't sharing parts within the company. The various A body's shared parts but seems crazy the B bodies shared nothing, must have been a lot of engineers working for GM.
