i did this and i had to have the calipers changed cuz when i bled the brake to get pressure again the bleeder screw broke,, but if you really want to , you have to take the wheel off(it also helps if you turn your wheel so that the calpier turns and you get get behind it better,, then there are 2 bolts.. youll see them take those out, and then get a pair of vice grips and pinch the brake line, and twist the caliper off the hose,(you may need to use a wrench to get it started. then wiggle the caliper off the rotor ,, clean it, prime it , and paint it. let it dry. connect the fluid hose. then bolt the caliper back on. and then youll see a lil nipple type screw,, (this is where i messed up) you unscrew it a 1/4 turn. (your gonna need to people to do this. while the bleeder screw is open. have the other person push the brake to the floor slowly. and once he hits the floor, tell him to hold it to the floor and to tell him to let you know its all the way down. now tighten the screw but be gentle,no tell him to let the brake pedal up , then losen the bleeder screw again 1/4 turn and do the following steps till you get the pressure back in the brakes. Warning this is what i know of front brakes. i have drum s in the back. im not sure this is how you do it for rear disc brakes. no if i left anything someone please fill in ,, thanks
