On my front hydraulic brakes, the inside pad closest to the hub is fairly thick, but on the other side I can't see any pad at all. Coming down a steep hill there was some screeching and the brakes weren't gripping and stopping well. Is this an install problem? Possibly something worn out or warped? The disc rotor has visible marks on it but no scoring or grooves. The front brakes are Shimano Deore 160MM Hydraulic. I get them serviced regularly at a professional shop.
UPDATE: The shop replaced the front and rear rotors and both sets of pads. Cost for labor and parts, €120. The rotors were quite worn and the thickness was below the suggested minimum. These were upgraded to Shimano SM-RT66; the stock rotors were the cheaper SM-RT56S. One thing I did not know: The 56S is softer metal and only resin pads should be used. The RT66 allows semi-metallic or resin pads. The 56S rotors lasted for 10,340 KM, with a lot of hard wear, and at least one set of semi-metallic pads that shouldn't have been used. I imagine the RT66 should last maybe 15,000 KM.
Update #2--After 5 months with the Shimano SM-RT66 rotors, I'm amazed. Braking is far better than it was. The pads are still OK after a full summer of riding. I suspect that semi-metallic pads were used on the old rotors and they didn't grip well and they wore out fairly quick.
Update #3--Still haven't replaced the brake pads. Haven't been riding as much due to the cold weather, but still these are lasting much longer. And for f's sake, enough already about the brake go-round. Get what works and forget about it. Learn as you go. Be open to surprises.
