[QUOTE=What is pad knock back?[/QUOTE]


Pad knock back occurs when you have end-play in your rear-end that pushed the disc brake pads off the rotor (even a few 1/1000ths) - the result is a spongy petal. It is very common with GM c-clip rear-ends when you put fixed callipers on. Worse yet, the pads are always pushed back in varying amounts (depending on cornering force) so you never have any clue how spongy the petal is going to be. Kinda annoying when your heading into a 180 corner at 100 mph.

If anyone is considering doing a disc brake conversion, you should understand this issue - or it will cost you time and money.

As I said, a residual valve is a bandaid fix, a proper fix would be a floater rear-end, floater callipers, or a c-clip eliminator kit, but it must be a "circle track" not a "drag racing" c-lip eliminator kit.

This is a huge subject - I'll post a new thread on the topic and expand on the proper solutions. I don't want any of you to go through what I did.
