In addition, there is a limit to the number of units for which UC grants credit in the following areas: 1  English as a Second Language courses: a maximum of 8 semester (12 quarter) units. 2  Physical Education activity courses: a maximum of 4 semester (6 quarter) units.
As a rough guide, rotors should cost about $75 apiece, front pads about $110, rear pads about $60, labor to replace pads about 1 hour per SET of two wheels (a bit more for the back, 1.2) and each rotor removed takes about .2 of an hour.
No decent repair shop will charge $500.00 just to change the brake pads. On the other hand, if the rotors need serious fixing (beyond the general buffing), that will cause a quote like that pop up. Last year, my brakes and rotors got so bad that I needed to replace them, and that cost about $400.
