E-brake lock-up!!!

Houm_WA,
Good starting point!

The trick to avoiding the problem is regular use of the EPB and regular stripping and servicing of the brake parts on the rear wheels, especially after off-roading. The actuator is very expensive and a pain to replace as has been noted. To give an example, the job done by a good indy in the UK was around £900 (say $1200?) on a V8 a few years ago. It's not an easy DIY.

There's a great DIY page on the UK disco3 site by Bodsy. Not using it in the UK is not an option as it gets tested annually at the road worthiness test, hence the recommendation to use it every time the car is parked.

I had the squeal and lock up a few years back on my 06 and I cleared the codes to release it. But it would come back intermittently. I also used Bodsy's break bible from the UK site to adjust and bed in the parking break and it has never returned. It is and easy process.

So Trynian you solved the problem be re-bedding and did not change hardware?

I had been using the EPB every time I parked; I made it a habit. It's a great feature.
I'll have my indy/Brit Auto specialist run an OBD scan to check the condition of the actuator. He said there are no after-market parts for this; only Land Rover 'brand'. He also said that he has seen more of this type of behavior on Jags, but not that much on Rovers...

I don't want to jinx myself or anyone else, but it does seem that once changed, the actuator has behaved itself pretty well, even if it's the same damn part.

When I purchased my LR3 3yrs ago the complete left side EPB shoes and hardware were missing, now the right side had to be removed till I get a new actuator installed.. This seems like a common problem

I am currently experiencing a common issue. After replacing my rear brakes and rotors my emergency brake has locked up. Brakes over heated and I ended up having to replace the shoes and rotors for a second time. Can anyone tell me what I'm doing wrong? 1st time poster any suggestions are appreciated.

it is possible that you may have a spring or the metal bar in wrong. I always chamfer the narrow ends of brake shoes so that they do not pick up until bedded in. Did you tighten the adjusting screw up till brakes shoes were centred in hub and you cannot turn hub, then back them off eight (8) clicks, sounds a lot but it is not. Hub should spin freely.

It sounds like you do not yet know about Bodsy's Brake Bible.

Below are links on disco3 to Bodsy’s Brake Bible, a free 36 page pdf containing all you need to know about all three brake "systems" on the 3.

Download the latest version; v1.6a. As of when I last looked, there has been over 17,000 views/downloads of his free 36 page pdf. I see he now has a French edition as well.

The black art part is probably towards the end, (page 27/36 and following), re the electronic parking brake.

Rather than perhaps black art stuff, it may better be called leading edge, or maybe bleeding); also the set and unset procedure applies when doing just a normal rear pad change.

If you ignore the set unset procedure, then a few miles down the road, the squealing will almost assuredly start.

The good news is the fronts are more normal, but the rears, not so!

In total, for the vehicle, you actually have three pair of brake assemblies to deal with: (1), the front pair of rotors, and pads, (2), the rear pair of rotors and pads, and then (3), the parking brake pair of drums and shoes – yes, drums and shoes sitting behind/inside the rear rotors.

That is why you can use the parking brake as a “dynamic” system to safely slow the vehicle from highway speeds. The owner’s handbook explains the procedure as below.

Dynamic operation: In an emergency, the park brake can be applied dynamically: i.e. with the vehicle travelling at more than 3 km/h (2 mph). Pulling up on the lever and holding it up gives a gradual reduction in speed. The brake warning indicator will illuminate accompanied by a harsh sound and “Caution! Parkbrake applied” appears on the message screen.

The stop lamps also will illuminate. Releasing or depressing the lever will cancel the parkbrake application.
