Hi All,
My apologies if this has been answered before --> What is the difference between the 1967 (& 68) B-Body disc brakes and 1965-1968 Corvette disc brakes?
Thanks,

Denis,

The piston bore size is bigger on the B-body calipers. They're commonly know by the rebuilders as the "Big Bore" calipers. The other calipers such as those used in the Corvettes and Chevelles use smaller pistons.

Hi Keith,
Thanks for the info. Are the caliper mounts interchangeable? I'm hoping to use common C3 caliper mounts with big bore calipers, if available.

If you can't find a 4 piston setup I used a single piston setup from a 69/70 GM B body car on my 66 these will fit back to 65
But you need to change the spindles and arms and have a complete setup .

Thanks. Actually, I do have the 69/70 brakes on my convertible and they work great. But I'm thinking about going original 4-piston for my hardtop.

Good luck finding a 4 piston setup for a B body
