brake caliper noise

for about a month now i have been hearing this god-awful rattling comming from the front end when i hit any kinda bump at any speed. first i thought it was my light assembly.... nope than i thought it could be the front fender.... nope so i went taping around with a rubber mallet only to find out its my caliper. i have no idea why it rattling... should i rebuild it? maybe new brake pads? i know the bolts aren't loose, i need your help!!

 

On the XJ 700 there are two (one per caliper) anti rattle plates mounted to keep pressure on the brake pads. Perhaps they aren't installed correctly/at all at your bike?

Mine was doing the same thing. Take off the caliper from the
pivot pin not the 2 bolts, sand clean and lub the pin, take out your pads and the anti rattle plates and bend the 2 tabs a little more and reinstall. your rattle should be gone. Some say you need to replace the anti rattle plate but this will work.

 

Thanks guys. that pin grease was so old it was like wax. i cleaned my entire caliper and pads with brake kleen reassembled and no more rattle! Thanks

 

Glad you got it worked out, that rattle can drive you nuts.

 

you better believe it. i was ready to just buy a new one if it didn't stop. Thanks again for your guys help!
