Ok, so i wa yed to put the car back down undercover so i put the caliper i couldnt get un stuck back on the car so i could get some braking ability.while breeding the brakes the piston popped free. So there is a new way to free a stock piston put it in without brake pads and have a person pump the shit out of the brakes.i had found a new piston on line so she is all good to go. She rolled down hill about a 120 ft. Now on to gas.
