  uneven front brake temps« » Reply  Edit


i've noticed that my right front brakes tend to be hotter ( and dust my rims more ) both during daily driving and track days. that said, i haven't noticed any pulling to either side during braking. during threshold braking, i can hear the front right tires barely locking up, while the left tire makes no noise.

i've checked the calipers and pins and they're fine, so i'm kinda stumped as to what's causing this. any suggestions?

I would check out the caliper sliders first and go from there.



I have no signature.

ive had problems with the rear... one time it was the slide wernt greased up and one time it was just the caliper sticking.

maybe check make sure the pads are seating properly?

How much of a difference in temps are we talking here?

i haven't had the chance to use a infrared thermometer to measure the temps, but the right brakes are noticeably hotter, as i can feel the heat when i put my hand near the rotor. the left also gets hot, just not as hot as the right. plus i can clearly see more brake dust on the right rim, especially after i've just cleaned my white rims

like i said calipers and pins aren't sticking, i've checked. i'm wondering if this is due to a difference in front weight ( driver seat always occupied, passenger seat always empty ) ?

I would guess the brake pressures from side to side are diffrent with the greater one being on the hotter side. I know you mentioned the car not pulling more to one side under braking though. Aside from all the stuff mentioned earlier maybe you could try a diffrent proportioning valve. The first thing I would do though is to check the temps with a pyrometer.

you could have an air bubble on the drivers side, creating more a difference of pressure in the calipers side to side.
