[Fot] Brake pads

[Duncan Charlton]

I used EBC Yellowstuff on recommendation of another racer but my experience was awful.  I followed my usual break-in procedure (progressively harder stops to get some heat in the pads and rotors, followed by a long run to cool the brakes) but during a subsequent race the pads felt like they were glazed.  I tried sanding them and the material came away in chunks.  I chanced it again but the brakes were not effective after the first few applications, and again I tried to sand them with the same results — the material crumbled.

If the attached picture can be viewed on this forum, you can see what happened when I poked the material with a small flat-bladed screwdriver.

We tried it and in one session we knew it was not a compound made to work at race temperatures.  Therefore, we went around the seller and we tracked down the company doing the relining for the seller .  The shop owner was really nice on the phone and they have confirmed what we thought in a test.  The lining that is being used is NOT FOR RACING PURPOSES.  It is a Cool-stop lining designed for street car use only.  The compound that is being misrepresented is made to work well at low temps.  That was a disappointing waste of $150 and a brake job……We ran them one weekend took them off.  Now the backing plates will now be sent for a proper race lining.
