    Default XM hand (foot) brake

    Hi,

    Advertisement


    I changed the front pads and rotors on the XM and, now the parking brake goes nearly all the way to the floor. The factory manual states that you hold it down to the floor with the motor running and the hydraulics will take up the slack but, when I did this it made no difference. Any ideas?

    thanks

    Warren

    You didn't break the springs in the calipers did you? The pistons needed to be wound in. To take up the slack, stand on the pedal a few times and the pistons should ratchet around and take up the slack.

    No, I turned the pistons in and the brakes are working fine, it is just the parking brake that is affected. Cables are all intact and, while loose at the calliper, are connected...

    It has probably popped out of the other end of the cable. It is in the transmission tunnel area. Just follow the cables from the front brakes back to what I consider to be an equaliser.

    My reading of the post says WRB is pressing the parking brake pedal and you are saying press the brake pedal to get it to adjust up, just like a BX takes up the handbrake when pressing the normal brake pedal. Assuming indeed that a cable hasn't popped out.

    Yeah, that's what it sounds like to me. The XM is just a "big bx". He needs to pump the brake pedal to ratchet the pistons adjusters back out. Same deal with the old ID/DS clockwork brakes too

    Okay, I will give it a go with the normal brake pedal and see what happens. The thing is though is that I have working brakes and rhe parking brake pedal does take up but, nearly all the way to the floor. Maybe one of the cables has popped out of the equaliser so, will have a look on the weekend

    No you need to pump the handbrake .... it should spin the pistons as it's applied (if I'm not confusing it with the "D" clockwork brakes). Each time you apply the handbrake it'll ratchet the pistons around slightly. If you wound the piston all the way in, it may need to ratchet out quite a bit

    I have found with my BX's that when the handbrake lever starts to run out of travel at the top, you need to do a few good panic stops with the normal brakes and this usually lowers the handbrake level by a few notches.

    In my experience, the brake pad wear is taken up during normal braking not when applying the handbrake.

    Cheers,

    Ken W

    And that, presumably, is the equivalent of the parking brake pedal being down to the floor.

    Well, one of the cables has fallen out of the balancer, unfortunately it is the top one. I undid the exhaust heat shield but, could not move it back far enough to be able to access the top cable. I tried to turn it around the muffler to remove it completely but, wouldn't come out. The muffler is going to have to come out and, unfortunately, it is the one that goes up to the catalytic convertor and, I cannot access the bolts at that end so - off to Paris Motors.

    No need to pump the foot brake pedal - push and hold firmly with engine running - and park brake released. Next application of park brake should see improvement. My BX failed a rego check years ago because of a slack park brake. Jumped in, started the engine, held the foot brake and then asked the mechanic to check the park brake again. Three clicks - PASS!
