I have a 2000 300ex and I let the pads get way too worn down once and now they are worn down to the metal after every ride. I installed a lsr p brake block off and sanded down the rotor to remover burrs from the holes in it and it didnt fix it. I also made sure the piston was moving in and out good and it was. An ideas?

sounds like the slide pin is locked up. take it out and grease it. dosent sound like its totally gone, but locks up enuff that the first time you hit your brakes, the pads stay squeezed. just a geuss

Ride in the mud a lot? If so get a stainless disk w/o holes. Mud will eat pads like it's noones business. It's like wet sandpaper.

But eating them down after every ride.. has to be a stuck brake.

Or, most likley your "sanding" marred up the face of the disk and it's acting like a file. You should probably go get it turned at an autoshop to true the face back up.

Or jsut replace it with the solid one if your riding in a lot of mud anyway.

mx428... calm down, I was just kidding. You got more offended by it than him!


Anyway, the rotor looks fine. I just meant to take off any burrs arouns the holes and I didnt sand on it a great deal. Also I put a LSR parking brake block off on it thinking it may help but it did nothing...

have you tried a new rotor? everything else i can think of has already been tried/said.
