i know this subject has been asked 1000s of time but can someone tell me what all parts should i remove from a 79 seville (or other vehicle)to convert my 72 chevelle wagon to disk brakes. i will be pulling parts at my local salvage yard.

i'm sorry i forgot to say it's a rear brake conversion i'm wanting to do

Welcome reggie.

You should post this in the Suspension and Brake forum.

It also has a subforum for brake conversions.

tks will do

I have a CPP kit that is based upon that Seville setup.

Use common sense and take everything attached to the end of the axle tube.

Brackets, bolts, rotors, calipers, ebrake lines, grab the junction block for the brake flex line. Mine came with a plate or spacer that goes behind the axle shaft.

Take pictures as you pull it apart to give you references on how to put it together.

Buy new rubber lines (3), pads, (rotors if needed). If you are missing any bolts or pins use grade 8 from the hardware store.

Take your time, easy to do.
