land rover discovery 3 electronic park brake fault

Anyone with a discovery 3 has more than likely experienced problems with the electronic park brake such as a loud squeeling noise from the rear when the switch is pulled. This one is the strangest fault I've seen, it actually plays a tune when applying the brake!!

What causes the high pitched scream they normally produce when out of adjustment? Is there a slipping clutch in the actuator or something?

[blinkynoo]

There are plastic gears inside the actuator and when the brake shoes are worn or out of adjustment the gears come to the end of their travel and slip, this causes the high pitched scream.

Thanks - so the rumour of a clutch in there is wrong (I thought so as window actuators etc don't use clutches). I'd like a Disco 3 but it sounds like it could be a nightmare once out of warranty.

[blinkynoo]

I dont think there's a clutch in there, long time since i've seen the inside of one so i can't remember. Reliability wise they're not too bad but yes they will be expensive to fix once the warranty is out, mainly due to labour costs as parts are not that expensive when compared to a range rover.

I do a lot of my own repair work - Dad was in the business and I had old Jags so I got plenty of practice 8-) but don't lots of jobs on the D3 need an LR interface to clear error codes, do calibrations etc so are off limits to the third-party mechanic?

[blinkynoo]

Yes they do, there's not alot you can do without a computer but software is available to communicate with the ECU's. All new landrovers have gone over to the ford/jaguar system using IDS. This system is available on ebay but it aint cheap.

Heads up Disco 3 owners - even though you can drove off the parkbrake and it will auto release, don't. - and if the parkbrake MUST be adjusted every service, it seems that these two tips should see you clear of any dramas!?

In my father in law's 2007 Discovery 3, I have encountered a very similar problem. The parking brake was not released automatically when driving with D position. The official dealership pinpointed EPB module was malfunctioned, therefore actuator, cable assembly, both parking brake shoes, and rotors had to be replaced. I did not find any parking brake red light on the dashboard but the parking brake was locked. Very common problem in Discovery 3. Contact a dealership for a repair.
