    good day all you disco lovers.

    need a bit of advice, father in laws got a 2006 tdv6 se, dash is saying that there is a park brake fault although it still works as normal and the gear number display doesnt show in the lower gears..

    i seem to remember that theres a common fault with the electric handbrake but cant remember what it is..

    any advice appreciated

    thanks
    rob

    Mate of mine has one and for a while the handbrake would suddenly engage for no reason. This was of particular concern to him the time it happened while he was doing 80 on the A30!

    I believe there was a recall regarding the park brake by Land Rover so check that the modification what ever it was has been done.
    Google for recalls on D3s.

    Try searching for a gearshift calibration thread.If the EPB ecu cannot see what gear the car has engaged it will log a fault and put up the park brake fault - even though there is probably nothing wrong with it.
    I cant remember the exact procedure for calibrating the x/y pots on the gear lever,I think its something like engage low range and drive through gears 1-6 for so many secs in each gear,then same in reverse.Worth a try before you take the wheels off or pay for diagnosis.;)

    Either the park brake module or wiring to it, not cheap either way, the new modules are on restricted supply as LR are aware that the new ones are still a bit iffy!
    Calibration will make no difference, diagnostic will show loss of communications.

    Well its worked on others and costs nothing,the one I did was exactly the same,the UCM was able to get comms with it and the recal worked - whats the harm in trying ?

    Have you managed to sort this yet ? I had another one in this morning with the parkbrake fault - brake works perfectly.But the gear shift display was lazy,taking several seconds to show what gear it was in.
    Looked up my notes and did the recal,in low range drive for more than 10 secs in each gear from 1-6 then reverse.(Done in low range cos its slower.)Switched it off for a little while to let all the ecu's to shut down,then fire it up.The gears show instantly and the park brake fault message was gone and the lamp went out.
    One happy customer,one happy me - cos I hate working on the sh-te.:D

    The parking brake should be serviced at every service, or else they are at a great risk of binding more when they are applied, sticking on in other words. It it does stick on when applied and won't auto unlock, if you remove the plastic cover from behind the switch about an inch by an inch square, there is a thin wire behind there, if you pull on that it should release the brake. You may need a pair of grips to get at it though. To service the brake you have to take the rear wheels off, there is a small cap on the brake disk drum take that off and turn the wheels until you see a small star wheel, attached to a bar, if you tighten the star with a screwdriver until the wheel drum won't turn by hand and then undo 8 clicks that is the correct setting for the handbrake this should be done preferably every year :)

    Pointless unless you remove and clean out the drums.Its all the rust/dust that causes the problems.
