Another brake question
Hey guys, just a few quick questions. Are my rotors suppose to be hott after a 10 minute drive in 20 degree weather? All four rotors are hot.
This is a stupid question but when I brake are all 4 brakes applied or just the 2 front? Are the rears just the e-brake?
My rear passenger side pads are rubbing against my rotors and you can hear that annoying shhhhhhhhhhhhhh sound. Are the pads suppose to be touching the rotors at all times? This wasn't happening it just randomly started just now when I took a 10 min drive to my gf house. I did my rotors and pads about 2 weeks ago. I was getting some rubbing up front but that's gone and everything was fine. Than all of sudden the rear one is rubbing. Please help. It's nothing serious but a simple pads and rotors replacement have been becoming a huge headache

Rotors will heat up very quickly, regardless of outside temps.
All 4 brakes are applied everytime you step on the pedal. About 70% of braking force is on the fronts and about 30% on the rears.
The pad should only touch the rotor when the pedal is applied. You may have a stuck caliper/piston if the pad does not retract when you remove pedal pressure.

Under normal conditions, that is to say normal braking conditions, your rotors should not get hot... as in really hot.
I had a bit of a disagreement with someone on this site several years ago about driving at superhighway speeds and how that really heated up the rotors. My position was the opposite is true. That unless you had to hard brake, just driving at 70+ MPH is not going to heat up the rotors.
It just so happened that I was close to taking a 440 mile trip south and I decided to do a little experiment. After four hours of driving, with three of those hours in I-95, I pulled off the highway for breakfast and as soon as I got out of my car, I felt my front rotors. They were cool to the touch.
