I have replaced all of the above in the past week. Normal driving breaks are A1 perfect. If I hit about 5 or so four way stops in a row and they heat up there is a grinding sound from the breaks being applied. I'm talking 5 30mph back to 0 very quickly they get hot and an aweful grinding sound happens. What on earth could this possibly be nothing looks out of Wack and when it cools off it's fine. This is a 2 wheel drive 05 supercab. Is it possible that the spindle nut holding the rotor on is a hair to tight? There is no warp or anything they are perfect till they get blazing hot I can't be having this grinding pulling a trailer on a long trip soon. Please help guys I had went back under and tightened the spindle nut a tad because I had slop in the tore right after I did it . Maybe to tight?

Its happened before, had one in the shop the other day, guy put in new pads and had a lot of grinding noise, he had one pad in backwards.

How is that possible when they are shaped to only go in 1 way arnt they? I did it all myself it's nothing to pull it off and check but wouldn't it do it all the time not just with prolonged stopping and going ?

Hold up backwards that means the back of the pad touching the rotor if that's what ur saying I deff didn't do that.

Did you grease the slide pins that hold the caliper. Those could be making noise. Also did you grease the back of the new pads where it touches the caliper? Both of these could be making the noise.

Did you ever figure out your problem?

I just completed similar brake, rotor, bearing work and rotors are very hot. So must be brakes dragging or bearings too tight to cause excessive heat. I don't have grinding just hot rotors.

How hot is normal for rotors with normal driving/braking?

I never checked them before doing the brake/bearing job so I don't know what normal "hot" is. Plus I live in Phoenix, so hot is typical. But if I am wrong and it hot because of a problem, then I am going to ruin my new bearings and/or pads and rotor.

So knowing the bearings sometimes get tightened too much, i checked the temp after driving and they were hot. I will take my IR thermometer and check them and report that here.

But to describe the "hot" (AND BOTH WHEELS FEEL SAME), the wheels are hot, but I can hold my hand on them. When I touch the rotor, i can't leave my finger on the rotor or I'll get burned.

Does anyone have rotor temperature data?

brake rotor may be wrong size or caliper mounted wrong so it sits closer to the rotor than normal so when the rotor gets hot you get metal on metal contact. this assumes your bearings are tightened properly and not loose
