Need help with Baer Brakes

[Bow Tie 67]

I had something similar happen at Gingerman last year. Although my rotors and pads were well seasoned. Mark Stielow used a term, which I can not remember for life of me, and said it was build up of uneven pad material on the rotors. He suggested easy light braking to help re-bed the rotors correctly, eventually the pulsing went away.

Bedding in brakes is a process of depositing an even layer of brake pad onto your rotors. As the brake system is used the layer is, in flux, its constantly being removed and replaced.

Disc Thickness Variation (DTV) maybe? It doesn't take much variation to get a pedal pulsation that you can feel. Also, as mentioned above, any looseness in the steering components (bushings, wheel bearings, tie-rod ends, ball joints, alignment settings, etc) can act to magnify the issue.

Wanted to let you guys know that I had the rotors "Blanchard" ground at a local place here in Tustin. Pretty cool setup--they measured each face--LF was dead nuts, RF was .003 front side and .004 backside--no more pulsation through the pedal, no vibration through the wheel. They took photos, etc and clearly knew what they were doing. I had spoken earlier in the week with a local outfit in So Cal called Porterfield racing, they deal specifically with brakes in racing applications. They backed up the blanchard grinding process as a great way to go verses throwing on a set of Hawk Blue pads to clean up the rotors. Spoke with Rick at Baer also and will be filling him in tomorrow as he was curious how this would work.

I can't find my pyrometer guage---but I could swear that the RF disc is running warmer than the LF---anyone else run into this?

Place that did the grinding was "Rimco" in Santa Ana--

What is blanchard grinding?
