Quick question for all. I am tracking down a siezed brakes issue. I have pulled out the pedal box and noted that I had no slack in the M/C pushrods. I have now adjusted these and have free play on both Front and rear, and with the bias bar set in the middle I appear to have good static balance.

While I was at it I had a look at both front Wilwood calipers. The pistons for one side of each caliper appeared to be stuck and the other pistons were very difficult to press back (when they did go back it wasn't a smooth slide into the caliper, but a jerk).

So I am going to pull out the pistons and check them and the seals. Anyone else done this and should they slide in and out smoothly or are they generally a bit stiff ?
