im working on swapping in a posi rear end from an '84 TA into my 92 RS. what else am i going to have to switch besides the proportioning valve and master cylinder to get the disc brakes to work correctly?

before this, the rear end was in my 82 z28 and it didnt quite work right. the pedal was somewhat weak and often went further to the floor than it should and still didnt stop as well as i think rear disc should.

i wasnt sure if there was a different master cylinder and stuff i should get instead of using the parts off of another '84 TA with rear disc to get the brakes to work better or not. let me know what you think.

thx

 

E-brake cables and either replace the calipers or rebuild them, they're probably stuck solid.
