rear disc conversion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I have an 86 c10 with power disc brakes in the front and drum in the rear. I would like to convert the rears to disc. Do you need to change the master or just the proportioning valve when you do this? Thanks for any help.

I forgot to add that I have a really lumpy cam in the motor. The lsa is about 110 degrees, so the brakes are a little sluggish due to the lack of vacuum as is.

Been reading some of the old threads. Can you use the front stock truck rotors with the 5x5 pattern on the back and use a mid 80's camaro caliper and buy or fab the mounting brackets?

If better brakes is what your looking for, the rear disc won't fix it. An ele. vac. pump would though.

You need to change both so you will have a Disc to Disc master and valve
