Squealing Tolerance Exceeded! Re-bedding Pads?
 

Hey all!

I don't think I bed my pads correctly. During the bedding process at the track, I'm pretty sure I was slamming on my breaks hard enough to engage ABS. From what I've read this can result in an uneven application of the pad surface to the rotor..The squealing happens at cruising speeds throughout town. Just ain't right for a new car to sound like this!! Before I resort to going back to stock, I MUST know-Can the pads be bedded over again?

FYI(1)The pads have at least 1K miles on them now.
FYI(2)pads=Carbotech XP10 F&R
FYI(3)My priorities as a driver: Street 1st, Track 2nd

Thanks,

XP10 = track pads.
Take a look at their heat range you will never be able to keep them quiet on the street no matter what.

Go rebed the pads. If they weren't squealing after your initial bed in, and are only squealing now that you've hammered them, go redo the bedding procedure. If you're running overly aggressive pads on the street, expect some noise though, there will always be trade offs with brakes (cars in general).

Also, if you were slamming the brakes hard enough to activate ABS, then you were NOT doing the bed in properly and your squealing issues are likely self-inflicted. Find an open, empty stretch of road and re-bed the brake pads, you should NOT be tripping ABS during the bed in.

Stay off of the ABS during bedding. The XP10 will be tolerable on the street, and only make a faint scratching noise, no crazy screeching or banshee wailing, once properly bedded.

If the pads were purchased from us, please follow the bedding instructions that we include with every race/semi-race pad order.

I had XP10s for a track day that were stock-quiet on the street at first. But after time they began to squeal again. I think it's because I naturally use very little brake. When I removed the pads to swtich back to a street pad, it looked like there was a build up of brake dust under the XP10s.

So I'm sure the XP10s will work on the street, but it would require moderate to hard use of the brakes to keep them clean and bedded.

Can you please PM me the instructions? Thank you!

Going to work on the rebed tonight!!

I knew to expect some noise when I bought the pads. Just, not this much noise.

Something isn't right because the pads are still squealing without me even tapping on the breaks. I can hear it as I cruise.

I took the instructions CSG Mike provided out to an open strip, and followed them step by step, making extra sure I wasn't jamming the breaks the way I did upon my initial bed-in. I must say I felt pretty good about my efforts..

What are my options now - besides putting the stock pads back on. I'm stubborn almost to a fault. The sound these pads are making is driving me insane.

My neighbor told me to get my rotors turned and that it can be done for $20. I'm thinking this may or may not work depending on the condition of the pads' surface. Hopefully the surface is even.

Any words of advice from those who have experienced this before?? Do I just keep bedding away until I succeed? The bedding process eats up gas quick and I'd rather minimize the time I spend doing this to save money.

Thanks,
AJ

Drive 'em cold for a week or two to scrape off the old transfer layer, then bed again.

Are you using any shims or anti-squeal lube on the back of the pads?

Nope. Is it advisable to use anti-squeal products?

Noted-I will bed them in a couple of weeks.

I'll do it for you...

I do.

If Mike's offering to bed them in for you...I'd do that.

Sweet!! :D

I'll PM you Mike.
