I put new front brakes on my RKing and I tried all the tricks except for the flipping the rotors. The things will not shut up. they just sizzle at all speeds. ???? I tried shims nope. I made shure the disc were alligned. the old ones began to squeak when stopping so I thought I would pur new dealer pads on them. I just put my old ones back on and they work like a charm no squeak or sizzle.... Any suggestions? Oh ya I have about 120 miles on them no hard braking and they have worn as expected. no high spots and making full contact on the rotors.
