Disco 3 parking brake failed during MOT

Adjustment is the first port of call. Then if that doesn't rectify the situation, the cause needs to be found. Get the cables checked where they rub on the lower arm guides. They can rub through the protective rubber, allowing water to enter the cable. This then causes a sticky cable, making correct adjustment difficult.
My money is on incorrect adjustment after the discs were replaced and lack of subsequent readjustment after the bed in process.

Electronic Parking Brake - why is it still using cables if it's electronic ? Sounds like a stupid system. My Audi has an EPB - when the rear discs/pads are changed you enter the thickness into the system. The EPB then keeps tabs on the wear rate and adjusts automatically.
Why have a system that requires a strip down every 6 months and adjustment due to cables and and wear! It's electronic!!
 
I am of the opinion that all this electronic "stuff" is just a way to make money - it seems to achieve nothing other than that.
Whilst the Audi system sounds more thought out - I am sure there will be "shortcomings" elsewhere for the purpose of extracting money.

At least with something that rusts away, I can weld new metal in
 
Wow a dearler recabling a park brake that's a suprise
My thoughts exactly. Most dealers replace the complete module. When I enquired about cables from my dealer, I got told that cables weren't available, only complete modules.
Parts only or supply and fit?

IME, most of the electronic "wizardry" on modern vehicles is carp.
What does this EPB actually achieve ? ( other than keeping LR in business, selling spares and repairs ).
It's there to add a degree of luxury I suspect. It's an expensive way to remove the traditional handbrake lever though. It's theoretically possible to fit a standard hand brake. Sadly the EPB unit is part of the CAN bus so it can't be removed with logging codes. Although it is theoretically possible to make an EPB ECU dummy unit. But that's as much work as replacing the unit in the first place.

You need a VCDS cable which is the equivalent of hawkeye/nanocom - but once you've changed your discs/pads you can leave it alone until the next change. You can also rewind the caliper back using the VCDS cable, so saves a little time.
Sounds like the landy engineers had a rummage around the parts bin and tried to cobble something together. Bonkers design, especially on a 4x4!

D2 all the way - at least it's all straight forward.....apart from the rust.....fuel pipes......injector harness......:rolleyes:

The actual actuator is mounted above the diff. This pulls on cables in the traditional way as other drum parking brakes. The Audi system, although better in idea, is completely different and much to vulnerable to off road damage. The Discovery system is pretty safe from off road damage. However it does require adjustment as the shoes have old fashioned manual adjusters. If the free play in the cables/ shoes exceeds the available movement of the actuator, it hits it's rack end stops and screams about it.
 
D2's are fine if you keep water out of the cabin, that's where most problems start.

We've had no electronics issues in our D2 V8 in 4 years since we did the sunroofs.
