I got my sons brakes the other week because he got new ones. His are in better shape then mine are so I turned the rotors and got all new pads. For some reason the rear brakes arnt really grabbing and the front ones work. But i have to pump the pedal to build pressure so the rear brakes work. And when you open the door I can hear a hiss from underneath the car. I checked to see if anything was leaking and couldnt find anything leaking anywhere. Sounds like air coming from somewhere but I have no clue where. If anyone has any clues to this mystery I could certainly use them. Thanks in advance.
