Are there any GM B-Body cars with rear disk brakes that can be used to convert a 1986 Caprice from rear drums to rear disk brakes? I know you can purchase a kit from Stainless Steel Brake Corp, but it's pricey at $710.00.

This caprice also has the stock 3.08 rear end gears. Are there any GM cars with taller gears that would fit a 1986 caprice?

1994-96 Impala SS and 9C1s both have rear disc and 3.08s as a general rule.

CD Smalley is correct. The B-body driveline is essentially the same. The 9C1/SS packages are the same as the station wagon.

However, those are different from what you'd typically find on "regular" B-body sedans.

I'd source a salvage yard. Be sure to include the master cylinder and proportioning valve to match the disc brake setup. Be careful.

No need for the valve. GM didn't change that either.... cheap @#$%@s.

I don't think you need the master cylinder either. You'd be better off using and adjustable proportioning valve.

I'm doing the rear disc brake swap on my 91 Caprice. It would seem from the replies, that this should swap right in, or will I have to deal with speed sensor issues? The donor diff is from a 96 police cruiser with 3:23 gears and posi. I know the parking brake cables are different at the rear caliper vs. the drum. I haven't picked up the new to me diff yet, so I didn't have a chance to check what the 96 diff has for calipers, but I also have a spare set of brackets, calipers, rotors etc., that were donated from a 94 taxi. I noticed the calipers were PBR brand. Is this standard? Thanks.
