Judder And Squeel At Sandown

[essay]

Hi all,

Can anyone assist with a continuing problem I am encountering with massive judder and squeel seemingly from the front left of my car. After a warm up lap it starts at turn 6 and gets progressively worse whereupon it's useless to persist. I can put up with the squeeling, but the judder is not good.

My brake set up is AP Racing with Ferodo Racing pads (2 very shortened track days old). I am about to take it in to be looked at (again) by my mechanic who suggest changing to a new pad compound (hawks). I never had this problem prior to changing the pads ( don't know what the prior pads were)

Thanks in advance.

The shuddering can be tyres, can be pad deposits on the rotors, can be warped rotors, From memory you are running the old GT Spec 6 pot APs, i would personally guess its pad deposits if its not there at high speeds when cold.

Hey Roy,

I am running 4 spot AP's. After the first incident at Sandown I took the car back to the mechanic thinking the pads were scrubbing on the alloy hat when hot, but i was told there was plenty of clearance, even though the aluminium hat is scored. I did a track day at Phillip Is after this without incident then Sandown and the same happens.
