FRONT SUSPENSION NOISY WHEN ON GRAVY ROADS BUT IF APPLY BRAKES,NOISE WILL GO OFF THEN ON AGAIN IF BRAKE IS RELEASE... IS IT THE BRAKE CALIPER AND WATS THE BEST SOLUTION?

Hii bro....its better if you intro urself 1st at here-->> http://www.sioloon.com/ice-breaking-f222/

about your problem..im not so sure whats the problem..usually when apply brake then will produce noise but your's quite dfferent...are the noise too loud bro??its not only the brake caliper can produce such noise..also other parts of sspension that broke,such as the bushing,tyre bearing,rotor disc..the best solution,i think you should bring your car to workshop and let the mchanic check it 1st to make sure whats the problem..
if your rear brake systm using the drum[not caliper] better check it..maybe the brake pad finish already,therefore whn you apply brake,noise will apply...
