jabri Posted July 28, 2013 Report Share Posted July 28, 2013 The parking brake of my Cadillac seems not working, even if applied the vehicle rolls slowly, does that mean I hv to replace the disk or is it to do with the pressure guage. Im not sure my friend suggested this option. Link to comment Share on other sites More sharing options...
boney Posted July 30, 2013 Report Share Posted July 30, 2013 You know parking brake pedal is held by friction of a spring around a cylinder. There is a toothed wheel on top of the cylinder that hold the wheel while connecting to the brake pedal. So as you apply and release the spring winds against the tooth wheel thus locking the force, so either the spring is weak or the toothed wheel does have enough teeth to hold on. Get it check at the service station, this is something we can only guess and do nothing. Link to comment Share on other sites More sharing options...
