Wheels getting super hot after driving ??
I didn't slam the brake hard... just regular driving from grocery store to home.
and I discovered that rear driver side rotor are getting super hot.. as hot as after hard braking..
but the rest of the rotors are relatively cooler...
One possibility might be pads rubbing the rotor while driving
what would be the proper way to correct the problem??
Or should i just take the rotor / pad apart, and clean them thoroughly ??
Thanks x9999

Re: Wheels getting super hot after driving ??
It's possible your caliper is seized and the pad is always coming into contact with the rotor. Remove the caliper and see if you can depress the piston. Since it's a rear caliper, realize the piston has to "screw" back in.
Re: Wheels getting super hot after driving ??
inspect the caliper, its bracket and compare the pads on the left caliper to the right caliper. uneven pad wear is usually one of the tell-tale signs that there might be an issue. since you stated you found the rear right rotor relatively hot in comparision to the other 3 corners, it's also an indication that you might have a lock-up & your caliper seems to be seized.
the pin on the bracket (which is housed by a rubber boot) should my freely. if not, it could possibly be seized due to lack of grease. seized pins can be broken loose with a breaker bar and re-greased before re-installing.
get the wheels off, inpect the right and left rear brake pads then compare them. when uneven pad wear occurs, it's an indication of a caliper not working correctly. next, i would try to source where the seizing, binding or locking is occurring. i would remove the caliper (they're held on by two bolts) & push the piston back. in your case, since we're discussing a rear disc caliper, you'll have to turn the piston in and have the e-brake in the OFF position. seized parts are the result of improper service or lack of lube.
1. check for rust on the caliper piston
2. look at the condition of the seal (or o-ring) around the caliper piston.
3. after the piston is all the way in, push the brake pedal & inspect the piston once again for rust
4. also check for ripped rubber grease boots on the brackets. this part, which holds the bracket and caliper together on a bolt should slide & spin freely (can be broken free w/ breaker bar)
5. with the rear of your car up, put the e-brake is in the ON position & try to turn each rear wheel.
6. make sure the e-brake cable moves back-and-forth freely...if there's binding, pick up a can of silicone spray
i would repeat the same procedure for the other calipers

Re: Wheels getting super hot after driving ??
Today I took the Driver Rear side brake apart and inspect
I lubed the slider, clean all the bolts, caliper wasn't seized
I found out that PBR ultimate Pad is a bit larger than the shim ends
the pad was stuck ... thus dragging the rotor
I grind the pad (both ends) down a bit and it works perfectly fine now

Re: Wheels getting super hot after driving ??
glad you took the rear right caliper assembly apart; definately surprised to hear it your pbr ultimate pads. great work grinding down the pads...good to hear you've found the culprit & eliminated your problem
