Hi classical glass. It has been often said by forum members and stated in pad instructions to "roughen the pads and rotors".

But I have yet to see specific instructions on how to do it.

Roughen by hand or by mechanical means (like a sanding disc on an sir tool)?

Grit of the abrasive used?

Cleaning instructions (Brakekleen or thinners)?

This info would be helpful.

Cheers

I used 80 grit on a 2" sanding disk on a right angle air grinder. Lightly run the disk over the rotors as you spin them, sand the inner and outer side of the rotor. Be extra carful not to gouge the surface of the rotors. I always use "Brake Clean" (green label) to wash and clean all brake parts.It's really not that difficult, just take your time. Good luck.....

When I did my back inboard brakes I used 80 grit on a sanding block,. I would not use a sanding disc! The block insures you will not gouge the rotor. It was a ton of work and very awkward to do. If there was more room to work I would say a palm held DA might work pretty good.

I have Wilwood calipers with the BP10 pad material and the brakes lack initial bite and overall stopping power. I'm interested in changing to a different pad material to see if I get improved brake performance.

Does anyone have experience of changing from Wilwood BP10 to say Hawk HPS?

As I've written before, I have the big Sierras, not Wilwood. But one of the reasons I went with the Hawk pads I referenced was that my existing "soft" Sierra racing pads sounded like a garbage truck at certain times, usually when I was easing down a hill or coming to a stoplight. A fellow ERA owner told me that not only did the Hawks increase non-racing stopping power, but that they eliminated the squeal and groan. I can truthfully say that, since I installed the Hawks, I have not heard a single squeal or groan from them. And, I did not use the shims nor did I use any anti-squeal goo. I just pulled out the old pads and stuffed in the new ones.:cool:
