I need to take apart my rear brake caliber to sand the pads. I think I may have "glazed" them. This is what Helmut suggested. How do I properly take the caliber apart. Never did it before. I have a 2007 400 ex. There are 2 bolts that look like I would loosen to take apart but they have metal washers that close the one side up so I cannot get socket on. Should I bend that down and put socket on anyway. Does anyone know what I'm talking about. I need help please. And once I get pads access I just sand them and sand my rotor as well? I still have this squeaking noise when i press foot pedal down and slightly when I drift the bike. Sounds like rubbing. Driving me crazy.:shocked:

Yeah, just bend those tabs up until you can get the socket on. Those tabs are just to keep the bolts from loosening up.

And once I get pads access I just sand them and sand my rotor as well?
Yeah, the ideal is to just roughen the surface of the brake pads and brake rotor. It won't take much sanding. When sanding the rotor, sand in circular motions, so as to leave little circles all the way around the rotor. Again, you're not really trying to remove any material, just scuff it up some so it's not slick.

Well Helmut. I did everything as you said. No luck but I now understand how my brake system works. thanks for all the advice. However when I was doing this I noticed when taking the pads out that one was bent and they are pretty skinny. Ive had the quad since april. So i dont know, do you think the pads are shot already? how long do they usually last. i do use my back brake the most too and ride 3 times a week. So any suggestions on brake pads to purchase? plus when doing this. I pushed the brake piston all the way in and also pad spring (i think this is what its called) was sticking and it may be the problem. I pushed it and it got loose but the 2 rubber pieces which cushion it may not be working properly. Is that possible? please let me know thanks!!

The new brake shoes may fix the problem and don't forget to lube the pins with brake lube, like Tom suggested.
