    I have never heard of the pawl failing in a D3 and I have had autos since 1971 and never had any issues.
    This is the recommendation of manufacturers, and there are plenty of documented cases of broken pawls.

    It's a bit like smoking, not every one who smokes dies of lung cancer but the evidence is that it kills enough to make doing it a bad idea. Doesn't stop plenty of people dong it though.

    I have always rested my vehicle on the parking brake and the pawl is not broken - that's my basis.

    But don't take just my word for it, as this document also makes the same caution:

    [ame="http://en.wikipedia.org/wiki/Parking_pawl"]Parking pawl - Wikipedia, the free encyclopedia[/ame]

    Anyway, we are getting away from the main topic - the electronic park brake is there to secure the vehicle and if it keeps failing there is some other reason for why this keeps happening.

    I suspect the root cause has not yet been found, so continual replacement of parts will not properly address the repeated failures.

    I agree completely - the reason is actually well known - the weak components in the actuator module - there is a post maybe a year ago with a full explanation how the cheap plastic components strip etc.

    Yes lack of adjustment and dirt in the brakes can cause the issue - but if the actuator module was robust enough there would not be failures.

    I cannot find the post but others may be able to find it.

    I wonder why Land Rover haven't given this issue the arrest ion that it deserves, as the electronic park brake, to me anyway, is a safety device. Surely by now, after countless EPB warranty claims from D3, D4 and RRS owners worldwide, this matter would be well known to the boffins at LR.

    No it does not.

    From what has been explained to me by a LR tech, it fails due to muddy water ingress.

    Good to be part of this forum some interesting topics.

    The EPB module must be adjusted correctly as per Land Rover spec
    also it is recommended by Land Rover to have the hand brake shoes
    cleaned "washed" after driving through dirt or mud (offroad) and is
    actually noteein the owners manual.

    Regards

    That's true, and mine failed after a long trip on red dirt roads, but that is clearly a design fault in an offroad vehicle.

    In my opinion the only design fault is that the rear EPB shoes don't have an
    automatic adjustment as it wears.

    The rear shoes must be adjusted to a specific gap.

    The screeching sound your hearing is due to the rear module motor
    gears going beyond its limit due to the much larger gap.

    How this happens sand paper effect from mud and dirt.
