I just inspected and replaced the rear brake pads on my 16v. The passenger side pads were warn more than the drivers side pads. Anyone have an idea of what would cause this? The calipers looked OK and the pistons retracted easily. Could this be caused by a master cylinder problem?

how the mc could do that.

a restricted brake line on one side maybe. or rough rotor, maybe. also the caliper could be restricting movement on one side more than the other. take the pads out and grind down the edges of the ones that are less worn.

i always grind the edges down if nec to assure they are free to move in the caliper. i also apply a little grease on the edges of the pads. not much.

Thanks for the response. I still do not have a clear understanding of what is happening. I replaced the brake hoses a couple of years ago with SS Teflon lined hoses. I don't think that it is the calipers as they are the two piston type and both pads were warn equally.

I have installed new pads and I'll flush the fluid this spring before I take it on the track. I am not overly concerned but just curious.
