1999 Toyota 4Runner .front brakes

first you have to clean the surface of the brake pads, with a sand paper to make it rought and as well the brake disc and then return evry thing back it will not make noise if the pads are origional.

To change these pads is simple. You first should wash down the area with brake clean so you don't inhale the dust. Then they are to pins that go through the top of the pads and the caliper. (This Caliper has pistons on bothsides) You them remove the metal clips that hold those two pins. with a needle nose pliers. after removing the clips you will be able to remove the two pins and remove pads. Using the old pads in place you can then push back the piston to make room for the new pads.
