Author Message   Truk Posted on Monday, January 02, 2006 - 02:55 pm:        Started having problems with the front brake rotor grabbing /pulsing/ chattering with really aggressive braking. Works fine otherwise. Also brake lever travel is fine and consistent. I have tightened Steering Bearings in the past. It is not that. Others have suggested it might be hot spots or glazing instead of warping and at this point I am inclined to agree. Two suggestions have been offered. Clean the rotors, and/or change my pads to Lyndall Gold Carbon Kevlar Pads. Want to first clean the rotor and mounting fastners area. Any suggestions how best to do both the rotor and mounting fastners area would be appreciated. I have brake cleaner from Autozone. Is that OK to use on the rotor mounting bushings and fastners? Are the bushings rubber or plastic. If so would they be damaged by the Brake Cleaner? The back of the aerosol can of Brake Cleaner warns to protect plastic and rubber parts from the spray. Any thing I need to be careful of? What is the best way to clean the rotor itself? Thanks in advance for your comments   Buellistic Posted on Monday, January 02, 2006 - 03:23 pm:        Truk: What is the YEAR and MODEL of your BUELL ??? If you have a TUBE FRAME the Harley-Davidson TECHNICIAN TIRE CHANGERS have been known to BEND the FRONT ROTOR !!! If that is not the case you can break the glaze on the pads by rubbing them on your concrete drive way ... The cheapest AutoZone break cleaner will do the job on the rotor ...

You can freshen up the pad surface similarly by removing them and putting the emory paper on a flat surface and lightly working the pad face on the paper. My driveway is too uneven and made of asphalt. Others have found that the stock pads impart an intermittent mottled appearing glazing of some sort that causes the pulsing. New aftermarket pads, such as the Lindals have eliminated the pulsing.   Buellistic Posted on Monday, January 02, 2006 - 06:08 pm:        If the ROTOR is glazed, remove it ... With a rotorary sanding disc, make a light hatch pattern which aids in breaking in the system ...

Got my pads changed today and everything is working fine. I did use the LRB/ Lyndal Gold racing brake pads. Followed the break in procedure. Changed brake fluid - Motul RBF 600. Cleaned rotor and rotor fasteners Bye Bye grabbing /pulsing/ chattering.
