Title: Knocking sound in frnt brake after 600 mile svc?
Post by: bricks on December 26, 2004, 03:44:34 PM
Hello All,

I just purchased the 2004 GS500, when I had it serviced for the first 600 mile service I noticed the front brake made a knock or pop sound when I use the brake. It happens mostly in the begining of a ride but I am concerned. I asked the shop, and the tech said it is normal due to the floating caliper. The caliper and pad seem tight. Any Ideas?
Any easy way to lube the chain myself every 600?

Thanks everyone

Maybe the rings that connect the friction surface of the rotor to the inner hub are contacting your caliper mounting bracket?(http://www.bbburma.net/MiscFotos/100_1599_EBC_ProLite_Rotor_AfterTestRide.jpg)

Also, make sure the mounting bolts are tight; the upper one, if not tight enough, will allow the caliper to rotate forward and contact the fork leg each time you apply the brakes. If when the caliper is actuated, and potentially draws the forkleg towards the disk (or, vise versa) and the rings that Kerry mention contact the caliper, then you would hear a repetitive sound as each ring that passes by would contact the caliper.

Most likely just the rotor clicking against the buttons in the carrier. These are semi-floating rotors. Full-floating rotors do not have the wave washers in the buttons. Floating rotors lessen the chance to warp. Prior to riding, the rotor may get rotated backwards when you roll the bike backwards due to the drag of the pads. There is a little play in the buttons. After hitting the front brakes the rotor gets seated, the clicking will decrease. Plus the rotor heats up and expands. With the bike sitting, grab the cold rotor and typically you should be able to rotate it a little. As long as the caliper mounting bolts are tight, nothing to worry about.
Title: Thanks for all of your help

Thank you very much for all of the posts and pics. I do feel it is the floating rotor that dgyver mentions hit the nail on the head. I do love this bike.
Thanks again
