    Electric park brake

    This has only happened twice but today when getting out of the car and apply the EPB it made a very loud squeaky/scratchy noise which went for a few seconds

    Any ideas what has happened or causing this??

    There are heaps of threads on this.
    The EPB needs a good clean and adjustment,it should be done regularly at each service or so.
    There are also vids on U tube how to do it.
    i have never done it so sorry can't help

    the park brake shoes are inside the rear brake disc. As the brake shoes wear the EPB actuator has to pull further to apply the brake. You are now hearing it get to the end of its travel, and the risk of jamming increases.

    You now need to familiarise yourself with the procedure to manually disconnect the park brake actuator. Also note that when the car is in low range the EPB pulls itself on harder. So it is most likely going to cause it to jam if you apply the EPB in low range.

    The park brake shoes may still have enough material that an adjustment of the shoes will get you by for a while. Its garden variety brake shoe & drum set-up so any brake workshop can do it.

    I recall reading it in Landrover info, and it made sense to me. If you are in low range its a fair assumption that you are on a steep slope, or other precarious position. So the park brake needs extra force to hold the car.

    Hill hold function, as you imply in the original post, is not a function of the handbrake. It is a function of the ABS / Traction system. It's far better to have four wheels braked holding your position than the two rear ones from the EPB. And no, it does not use the EPB unless you activate it yourself so none of these are related topics. This is obvious with a window open as you can clearly hear the EPB motor actuating which does not happen when hill hold/decent control is active.

    That aside, the EPB of the OP sounds like it needs adjustment as has been stated.

    No. I wasnt talking about or implying Hill hold function. I was specifically referring to the operation of the park brake when in low range and when the car is parked and unattended. That was my recollection of how the function was described, and the recollection doesnt include hill hold function.

    I went through all this research when my car started doing the same thing...couple of warning screeches weeks apart.... emergency brake release on a remote coastal 4wd track... complete rebuild and adjustment of all park brake shoe / drum / disc assembly in my garage. So, yeah, been there done that so to speak.

    However, I will have a look and see if I can find the info.

    for starters:

    "Hi All . A little advice please… My EPB has started screeching when applied in low gear. It only does this in low, in high it works just fine."

    response: "The computer applies the park brake harder when in low range. If you can always remember to move to high before applying, it may live happily for a few more months."

    the work I did on my car predates this post but I recall seeing it in Landrover info, somewhere?
