Need Help With Squealing Breaks
 

On my kawasaki prairie 300 we got new breaks put on but after about 3 rides they started squealing and screeching really bad. The next time I went to bring it out it was dead so I tried to push it out but the breaks seemed locked so we loosened all the cables to the rear breaks and it has done nothing the breaks still squeal any advice on what to do or why they could be that way?

Find out if it is front or rear brakes that are sticking. The pivot cam in the backplate sometimes sticks on rear brakes, Hondas and Suzukis seem worse than Kawasakis for this but...
On front disc brakes, the sliders that the caliper move on can often stick, freeing them off is difficult, I usually remove pads and knock the caliper backwards and forwards along it's sliders until it frees, or at least can be removed, de-rusted and greased. The most difficult is a sticky piston. When you fit new pads, you shove the piston back in, and the part that hasn't been against the seals for ages is now being gripped by them. I had a plastic dust cover recently catch fire due to a sticky piston, after fitting new pads, so now make sure the piston can slide easily in the caliper.

Thanks man for the really quick response and the help I'll check it out later today gotta go to work
