rear brake problem
 

the problem is that my rear rotor is all grind up because of brakeing. so i was just wondering if all FR cars brake with all rotors, if not then theres something wrong with mine. i don't know if you guy could tell if your 240 is brakeing just the front or all. if you could help me see if FR car brake with all 4 rotors or just the front. thanks

yes they brake w/ all 4

the front does the most braking(weight transfers to front of the car)

its like 70 or 60% braking in front and 40 or 30% rear.. something like that

EDIT: this is why the front rotors are almost always bigger than the rears

YEp, get the rears replaced ASAP!

grinded up? ..have you changed your pads lately? take a look at your rotors, if they arent too grinded up you can turn them on the brake lave (i can't spell lol) possibly. I know the shop i work at, they charge around 20 bucks (each) to take them off, resurface them, and put them back on. Or you could just buy some cheap 30 buck brand new rotor at pep boys or something and slap them on by yourself :)

Im replaceing my back brakes right now, I cant seem to get one of the calpers compressed, any ideas on something that causes the calper not to compress, Hand brake is not active or anything

the rear piston has to be twisted clockwise while being pushed in... it's the E-brake self-adjustment thingy whatever maybe... take a pair of large needle-nosed pliers and twist the rear piston using the indents... don't forget to take your brake fluid res. cover off to make it easier to do... and try not to slip the needle nose pliers off or you might tear a rear seal... or your skin :thumb:
