i redid my rear brakes again yesterday. the problem i had was i had to floor my brake pedal to stop the car. i went back to take the calipers out, pushed the pistons out on both sides, then i twisted the pistons back in, the left rear was stuck the first time i did a check on it... but its ok now. i made sure i realigned the "+" on the piston to match that "." on the brake pads... bleeded the lines again.. and now its workin... bedding the brakes at the moment but im still thinking of upgrading all the parts for it (rotors, calipers, and pad).
