EPB Care
Hello,
What's people's advice on the best way to use the EPB - I'm thinking preventative here. My dealer sorted it under warranty last (and only) time - but I'm thinking preventing the faff of going to the dealers or being stranded rather than the cost.
i. Is to use it every time you come to a stop (traffic lights/parking etc) - to make sure all the parts are moved regularly - almost over-using it?
ii. Is it to only use it when you need to (parked on a slope - rather than just left in gear)?
iii. Is it to just forget about the potential issues and use it normally?
iv. Is it to avoid using the auto-release feature?
Thanks,

What DG says.
Call LRCC when you get charged. Eventually we will get through to them that there is more than 1 vehicle with the problem In the Beginning there was nothing, which exploded.
I am surprised no one has come up with a manual conversion yet. You may loose most of the arm rest box, but surely it would be worth it.
For the record I use mine about 8 times on a normal day, so far it just makes a noise when operating.

Agree with DG. It should just work regardless. Its self adjusting and should require no attention between services.
A manual hand brake never required such attention nor care it its use.

It shouldn't even wear out as the shoes only contact the drum when the vehicle has stopped.In the Beginning there was nothing, which exploded.

That's how I got mine done under warranty - something (dirt?) caused the shoes to stick and hence they were knackered when they looked at them. Knackered shoes on a 30k car = a warranty issue rather than a service issue.
The dealer almost seemed relieved that he could charge LR, not me, for the job.

Hmm, good question though.
Mine is fine, although I seldom bother to use it - only on steep slopes etc. or with a hefty tow on.
It does sound a bit 'dry', wonder if some greasing anywhere would help ? (but not on the shoes / pads or whatever its got !)
Presumably there's a little motor which the computers activate - this then moves levers & cams etc. to jam the shoes on / off. Thus manual / auto release should make no difference, its just a computer demand.
What gets stuck ? motor or the levers / actuators ?
I suppose I should read the EPB threads more closely .......

A motor above the diff pulls on the cables. Which in turn forces the shoes against the drum. When things run out of adjustment or become to slack. this is the noise thats heard, basically the motor has pulled the cables as far as it can go but things are still to slack. Type thing
Here is a pic of the EPB shoe

I think the issue here is that the widdly electric actuator is what it is and is very limited in the force it can apply ON, hence it can only be opposed by widdly little springs to move it OFF so the whole mechanism has to be able to move with a minimum of force in either direction hence sticks at the first opportunity.
Conversely a manual handbrake can apply lots of force ON (due to arm strength and leverage) and so can be opposed by decent springs to pull the shoes OFF - hence is much more robust. Add to it the relatively sheltered position of the transmission brake vs the EPB down-in-the crud location and it a problem waiting to happen.
I'd either use it every time to try and keep the mechanism free or not at all. Occasional use in particular circumstances only is probbaly going to cause more problems. Cheers

The problem is with the adjuster mechnism In the Beginning there was nothing, which exploded.

What detail then - many other cars in history have had problems with auto adjusters that have been solved by converting to a manual adjustment, more service effort traded for lower issues....is that possible with the EPB?Cheers

And does this get out of whack due to dirt / water ?
Or (I assume) its the brake shoes themselves the dealer cleans to try and fix the issue rather than checking the mechanism.
