Hello Guys,

I have about 4000 kms on my 400 and recently noticed when applying the brakes at noise coming from the front disc brake. It seems to happen at low speed (high speed application OK) so I thought maybe there was some dirt or dust on the pads or disc. Its like a rumble and not a squeal. The brake pads are fine but when I looked closely at the disc, there appears to be hairline type cracks in the disc. It is only in about 1/3 portion of the disc and I was wondering if anyone has experienced this as well. My dealership will be contacted and see if I can get this covered. Timothy

Brake Noise

Let me know what you find out...My front break is squealing a bit, but only when I use the right break lever. If I use the left linked lever, I get no noise.

that could have happened if the disc was really hot and you rode through a puddle or in the rain and got it wet, or if you washed it while it was hot

OK, I went to my dealer and he said he had never seen such a thing. He also commented that the disc appeared to be glazed and hence hinted that I wasn't pounding on the brakes hard enough. I tend to agree since I tend to be gentle. So that last couple of days I have intentionly been hitting hard on the front brake.

I don't think I super cooled the front disc after a hard run. The cracks appear to be surface and very narrow. It's like the cracks in an egg shell but I still get this crunching sound especially when I apply the brakes at low speed. I have contacted the Suzuki service rep here in western Canada and will follow up with them. Hopefully the disc won't crack up during a ride. Not likely but never say never.
