Re: D-30 Disc Brakes
Boy that first response was a lot of help wasn't it. This swap works really well. I used backing plates, loaded calipers, and brake hoses from a '78 Chevy 1/2 ton pickup. The nice thing about using the hoses is they are much longer than your stock ones and work well with a suspension lift installed. You will have to buy new wheel bearing hubs (not lockouts). The hubs you have now don't have a machined flat face on the side that goes outside of the rotors. It does take some grinding of the caliper and knuckle to make room for the caliper to move as the pads wear. Also, the inside pad won't quite slide between the caliper and rotor. You can shim the rotor/hub assembly out on the spindle or machine the brake pad slightly to get it to fit. I used the stock master cylinder with the residual pressure valve removed from the front line and it works fine. It is a great improvement over the drums and is about 1/2 the cost of the kit from Stainless Steel Brake Corp..
