HELP!!! Front Brakes
03/03/09 at 09:15:07

I have been having an on going problem with my right front brake caliper. I have a 2006 TRX450R. LOONNGG story short, it seems that when the right front is mounted (like normal) to the knuckle/spindle, it never squares with the rotor, hence never tightens all the way when I squeeze lever. I have already bought a brand new OEM knuckle AND rotor, it is still happening. When I dismount the caliper and hold it over the rotor, it tightens up perfect. I already checked the piston seals and dust seals. No leaks anywhere. Brake pads have plenty of life left. Could the pads be worn/bent wrong? The rubber bushings the rods slide into bad? PLEASE HELP!!!!

It sounds like the mount that attaches your caliper to the spindle is bent. I have had it happen a couple times. The first time I chased the problem the same as your are.

DEL152- It was a headache wasn't it?! Thanks a ton for your info, and 450racers.com thanks as well. It makes sense now. I had tried the spacers, although I was putting them behind the pads. That did not work, but I bet your way will. The only thing I do not know about is how much room I actually have to work with in between the rotor and the caliper itself. Only one way to find out! I will let you guys know Monday. I REALLY appreciate everyone's help!

Yes. The mounting plate on the caliper. It's removable and you can buy just the part that's needed. Last year I had a rock stuck in my wheel and had the pump my brakes the rest of the moto 2 to 3 times to get brakes. In between motos I checked the rotor but it was okay and switched the mounting plate and it fixed it. When the plate is bent it creates the same problem as if you had a bent rotor.

It worked boys! I had to put only one washer in between the caliper mount plate and the knuckle/spindle (the bottom mount). I also had to grind down the opposite side of the caliper mount plate so it did not rub up against the rotor. Only about 15 min of work. I might still purchase just the new mount like you have suggested. Thanks again guys, I appreciate it. Only one bad thing came out of this whole thing - I spent $92 on a new rotor and it looks like I did not even need one. darn! lol
