Front Brakes

[Butkus]

Mine sometimes makes one hell of a grinding sound when I stop. The disc does not seem to be scratched, the pads look even, and the brake pressure is fine. What could be the problem?

[S.O.A.N.Z]

Might have a stone stuck in the pads

That's what it sounds like to me but I don't see signs of it. I bought it brand-new and the noise begin the second I drove off the dealerships lot.

Grinding or does it go shhhhhhh ? That's normal.

Take the pads out and circular motion sidewalk swirl sand them. Or (harder in my opinion) sand them with actual sand paper.

Sounds like glazed pads

If the bike is new, bring it back and let them deal with it. That's what the warranty is for

[S.O.A.N.Z]

you didnt mention it was brand new - its probably just wearing in the new pads

Have you seated the new pads? They do not come seated from the factory.......

No, what is that exactly?

Pads come shipped with non-precision flatness.

Your disc is also not precision flat.

The goal is to make them both mate together with no gaps.

This takes gradual brake pressue to slowly wear away the pads so they mate with the disc.

Usually 10 min of 30 seconds on, 30 seconds cool down, either on a hill, or using throttle while breaking. Start light and gradually increase pressue.

The key is not not glaze the pad before it is seated, so there must be cool down each time.

If you just throw on the pads and ride, you are guaranteed to glaze the high spots on the pad/disc mating surface, making the brakes work poorly.

If you are using sintered pads, this is much more difficult, as they do not wear very fast, and they get extremely hot very fast. It takes longer.

I usually break mine in at the beginning of a ride, using throttle and brake at the same time, on and off over 20 min.

That sounds reasonable. My bike has about 700 miles on it. Hope it's not too late.

google bedding or burnishing brake pads.

[JoeRC51]

I've never done this in my 47 years of riding and I've never had any problems. Nobody does this on cars or planes either.

[bork]

I absolutely do it on all my cars, when changing out pads. I haven't had to do any shoes, since I haven't worn any out lately.

 

[notoriousE-R-I-C]

Ive never done it either, just sidewalk swirled.

My brakes dont have a chance to bed in

Krannie Mckranface hit the nail on the head with your brake problem. Do what the post suggested and your brake problem should be resolved.

It worked!
