View Full Version : Wilwood clutch MC side loaded?
As some are aware I had a Clutch MC failure recently. I sent my old MC back to Wildwood and they analyzed the MC to see why it failed. I received email from them this week with a picture of the piston and what happened. They are telling me the piston in MC was severely side loaded causing the leak. I am trying to wrap my head around how the piston would be side loaded with a Wilwood pedal box. The MC bolts up and the only adjustment I can see is the throw length. Anyone have any ideas how this piston would be side loaded? I definitely want to avoid this happening again it only lasted 2100 miles.
Thanks....

Did you tell them it was mounted in their pedal box? I'm also not aware of any adjustment that would change anything. I'm assuming the MC was bolted tight in its mounting location and the pedal pivot was either never disassembled or if it was re-assembled correctly.

60 years later this is the first time I have heard of that, you can still learn something new every day. Only thought, was the push rod bent?

Paul, yes the first thing I told them was it is on there pedal box. They have asked for pictures of the FFR Wilwood pedal box which I sent over to them today. The MC is bolted up with the two nuts to the flange, that is all I have done aside from setting the throw length. I never did anything that I am aware of that would cause the MC to have side to side movement.

Checked that too, just eye balled it but it looked fine to me. The rod threaded in to the pivot mechanism with no issues either.
