How many miles do you expect to get out of your brake pads, 6th gen.? My rear brake has chattered a couple of times, more of a low speed buzz, like running over thoes groves on the right side of the road to wake you up. I do live on a dirt road and try to wash out the dust as often as I can.
I noticed my rear brake doing that. It only does it every once in a while though. Thought I was the only one.
Much like the OEM tires, don't wait for them to wear out. I changed mine at 14000 miles & they had about 50% life remaining. I switched to EBC HH & there is no way the OEM pads can compare, the EBC's are that much better. They are between $25-$50 for a set depending on where you get them. All 3 calipers use the same pads. KC-10 FE out... lane: :usa2:
As of Sunday, I have new EBC brake pads. The rear ones were done while the front right had plenty left. I believe I got 20K miles out of them but can't assure since I lost my notes of when I changed them last.
I think my OEM set lasted around 20k, though I do a lot of highway commuting where I'm not using the brakes much. Replaced them with a set of Galfers that wore out in about 10-12k, followed them with EBCs that lasted up until I sold that particular bike. The EBC HHs are the best street pad on the market, bar none.
Keep in mind that if you're getting considerable wear on one side and not the other, that most likely is a loose rear wheel to axle issue. Since the hydraulic brake pistons must exert equal pressure on both sides, unless there is a fluid blockage, the only other explanation is excessive rear wheel play. Also keep in mind that the rotors will wear faster with pads that tend to "bite" harder. If you're going to ditch the stock pads, I'd stick a micrometer on the rotors when you change the pads and continue checking against the minimum thickness spec every so often. My 2005 RC51 was using an awful lot of lever travel to get hard braking done, even with the adjustable levers all the way out. 4000 miles or so before that began happening, I installed a set of golfer steel brake lines and EBC pads. My dad, rode it and we talked about what it was doing. "Have you checked the brake disks?" "No?" So I checked the disks and much to my surprise they were way under the minimum spec. A way-too-expensive set of Galfer super bike wave rotors later, everything was better than okay...
All you need is a can of brake cleaner-I use it before I ride-in dusty shit it doesn't take much to screw them up. Hit the buttons on the front real good. I was going to get new pads but just cleaning them-the pads starting working correctly.
