My new project came with what looks like multi piston disk brakes. Were these rare for 68 or actually even available? How much to rebuild these brakes(just parts) The car has been sitting since at least 1980 according to the paperwork. They look like they never came off the car. It is an alleged(no build sheet or engine but high redline tach) 375hp/4spd car and it also has 4.56 gears were these gears available from the factory? Thanks for any response.

Yes, four piston calipers were the disc brake option in '67 and '68. Good calipers...when they work right. As with the 'Vette until '83, the Chevelle 4-piston is, um, less than reliable. The pistons tend to seize in the bores, as well as leaking air into the caliper around the piston seal.

The 'Vette guys got so peeved, they begat the "stainless steel sleeve" rebuilders, who have since branched out into other-than-just-'Vette brake specialists.

The calipers, spindles, and rotors are harder to find than the single-piston floating caliper stuff from 69 and up. If you want to restore the car, (I would- sounds like a fairly rare unit!) pony up the bucks and keep the 4-piston stuff. If this is a daily driver, sell the 4-piston assembly and go with newer brakes. It'll cost less to get the whole single piston assy. out of a junkyard and rebuild it, than to do a proper rebuild on the original stuff.

The experience i have with these brakes is they work great if they are used often (driven allot). Otherwise they like to leak. They are difficult to rebuild and if you have never done them before might require two sets of seals per caliper. They are quite fragile and like to tear. Dont know about the 456 from factory....sounds interesting though. Please post follow up story.
