Anyone else had any front brake problems? I have had nothing but. I bought mine used in november and I have never felt good about the brake. I have ruined 2 rotors with an improperly installed caliper bolt. I have bled the brakes, changed the pads and it was good for like 10 minutes. Now I have this sporatic ghost living in my brake line. Sometimes when I go to grab my brakes it will be fine, sometimes it will feel like a -7 setting and other times a 12. It goes from almost touching the grip to barely being able to pull it a mm. Its gotta be the master cylinder, right? It always stops me, I just have no idea where its going to decide to grab. ANyone else? | ||

Dugallery- If you changed brake pads, make sure you cleaned the brake dust off the caliper pistons before you pushed them back into the caliper. They get brake dust all over them and if you push them in without cleaning them first, the dust will cause them to hang up in the seals, drag, come on without warning, all kinds of weird stuff. If you didn't do this, remove the caliper, carefully pump the pistons out using the brake lever, and polish the pistons clean with an old T-shirt. I have read that Simple Green and an old toothbrush works well. When they are spotless, then push them back into the caliper and reinstall. | ||

Thanks man. I put some rbf600 racing fluid in and it seems to be kickin like chicken, but the caliper piston info is handy to know. | ||

Hey Mark! Sorry about your brake problems. The only thing that bothered me was the pulsing, other than that, it SEEMED to work fine. Guess I just never rode it as hard as you...  | ||

From the initial description, it almost sounds like there is an issue causing the rotor to kick the pads back in, and retracting the caliper pistons. Symptoms would be first squeeze on the brake would happen with lots of lever travel, next squeeze brakes would engage with far less lever travel. Or it could have just been air in the system migrating around. | ||

My 06 front brake is making a tapping noise when applied at slower speeds. Maybe I do not hear it going faster. The pads were replaced a few months ago. I have had the pulsing feeling for some time now so that has not changed. When feeling the pads, the outside pad has a front/back freeplay of about 1/32". Wondering if that along with the rotor age is causing this? Has anyone tried lightly using a circular motion with emery cloth to the rotors? Otherwise the brakes work fine. | ||

Brown-e.... I started out with emery paper but have gone to a 4 inch knotted wire wheel on the rotor..this cleans up the brake pad residue and eliminates most of the pulsing brake lever. | ||

I went to Lyndall Gold pads, never a problem since. | ||

I have another thought: Did you use new mounting hardware when put the floating disc on the wheel. If the disc moves side to side, ie. If it wobbles, it can open the calipers and make it feel like you just grabbed a hand full of air. The first grab pumps the caliper shut and the second grab clamps down on the rotor and feels like a lot of brake. |
