I have recently bought the B pads for track use. They perform as expected , very consistance at higher temp where the E pads would have given up. After the track day I was too lazy to swap the pads and drove on them for a few days. Now my front wheels are covered with rusted metalic dust and it doesn't come off after washing :impatient . Then I decided it was time to change the pads and I found the metalic dust cover all of the brake pistons where brake cleaner didn't help much. I ended up using fine wet sand paper to clean those pistons. Any one know how to remove the rusted metalic dust from my wheels?

Cheers

 

I guess it's a bit late now. Never wash the brake dust from the car when using high metal content pads. The dust sticks. Blow it off with compressed air.

Removing this can be time consuming. Getting it off the pistons can be done with some scotch brite pads.

These pads will not dust this much when used on the track where temps are elevated. The breakdown seems to come from lower temp operations. J compound is especially bad for this. I have known a set of rotors to be eat up in less than a week of regular street driving. Stopped real well though...

 

Emm, I didn't think of the Scotchbrite. Do you think I might have ruin the pistons with the sand paper (very fine #1200)?

Cheers

 

I'd not pull the pistons and sand them with too heavy a paper. Sounds like deep marks on them could lead to other problems. The SB is all I ever use on them.

 

What other problems I might get Todd?

 

I'm confident you'll clean them up ok. Just remember not to use the real race pads on the street!

I think a lot of folks don't realize what real track pads are and how much bite they have. We all speak of "performance" pads. That's sales jargon. Then people think their new car is somehow a race car and they need this type of racing pad. Many racing pads don't work in properly until they see ultra high temps.
