[DeTomaso] Wilwood Brakes WTF????

[Jim Wallace]

Mike,
 
I replaced my rotors with Colman.....and replaced the hats direct with Wilwood seeing that I could not get any other satisfaction.....  Still the same problem once the rotors got heated up there was juttering.  Changed the pads to porterfield.....even worse. Had the rotors cut on the car for nearly zero run out. Fought this issue for 3 years and lost my ass everytime I went to a drving event as I was not able to participate.....then moved the the RX-7.  There is something a-miss with this set up.  I have been exposed to others with P-Car's and the same set-up with the same issue epecially at track events.
 
If you able to figure it out, let me know.....one of the bigger mysteries I could not solve.  I am thinking the aluminum block that extendes the mouting of the 
calipers from their original location creates an unstable "moment arm" that feeds back through the steering system.

I suggest if you want a sustem that will work correctly at the track, get something other than Wilwood as this system just does not work well with our package on the P-Cars.


>>>I had the jumping steering wheel syndrome until I had the rotors turned on the car, and that totally fixed it.  But with this recent episode, it appears the pistons got cocked in the bores which would have led to uneven braking and general weirdness.

Having said that, the rotors I have are the cheapest you could get; I am going to upgrade them soon.  I also have purchased a fairly rudimentary brake cooling ducting system, so we'll see if that has any effect.

It sounds like I am just going to rebuild the calipers, fit new pads, and hope for the best, although I am going to speak with Wilwood's tech department tomorrow morning to see what they have to say.
