noisy brakes (bmw) nklr

[mark ward]

Hey all My other bike (& KLR650)I just picked up Fri. is a BMW (2000) K1200lt, the back brakes squeak/Squeal, when applied, the shop said the "pads" were glazed, I just need to use harder for a while, to remove the glazing. (lots! of brake dust on the rim, and plenty of pad left.) I, thought rotors glazed, Not pads. Anyone who Realy knows brakes, Please advise. (ok, beamer & street bike, jokes welcome too. LOL) Mark (32nd) West Mi.

#ygrps-yiv-1991981918 p {margin:0;}It is definitely the pads that glaze over.  It could be that, or it could be the pads vibrating in their seats. To fix: If the pads are truly glazed (?), just put them against a sander with some 120 grit paper to remove the glazed surface.  Glazing usually only happens if you overheat the brakes or a foreign substance gets on the surface of the pad. If they're not, get some brake "stop squeak".  It's a black greasy paste that you smear on the BACK of the pads (between the metal plate and your brake piston).  This attenuates squeak caused by vibration between the pad and piston.  Some pads ship with a thin metal shim with or without an adhesive back that does the same thing, although I've never seen bike pads like that, only car/truck pads. -Jeff Khoury [b]From: [/b]"mark ward" [b]To: [/b]"List KLR" DSN_KLR650@yahoogroups.com>, glds@...

You can also do the car pad tricks: 1)wipe grease on the back of the pads where the pistons push on the pads. Use very little so it won't/can't migrate. 2)use what we call elephant sperm; the anti-squeal stuff that is available at almost all auto parts stores that you put on the back of the pad. 3)turn the rotor or replace the rotor(don't bother unless you have money to burn)

<><><><><><> <><><><><><> Mark, I'm not familiar with K bikes or most newer BMWs but brakes are brakes for the most part. It's the pads that glaze but the rotors can hold/carry contaminants. If it was me in your situation here's what I'd try... Clean the rotor with brake cleaner. Wipe it down until you have a clean rag coming off the rotor. Take about 10 aggressive but safe stops from 60 to almost stopped. Maybe allow 15-20 seconds between stops. If that doesn't stop the squeak I'd clean the pads with brake cleaner and then lightly sand them. I'd probably take a file and touch the leading edge of each pad so they wouldn't catch the rotor and cause a vibration. Clean again after sanding. And I'd clean the rotor again too. Then I'd probably try the 10 stop technique again unless the noise was stopped sooner. Good luck and enjoy your new bike.
