Rear brake adjustment steps, is pulling EPB fuse needed?
Hello LR team.
Question for those who tackled a full rear brake job on Discovery 3/ LR3 auto.
I have read Bodsy's Brake Bible, but nowhere to be found is an information on correct sequence when to put back a EPB engine bay fuse, is it before I make adjustment steps, after full rest with adjustment wheel and allen key or after it is all done? Or maybe it does not matter ?
Please shed some light as I have never done the full rear brake replacement, only front and brake pads. I am sort of hesitant to do full rear. Thank you

I did mine ages ago and I don't recall pulling any fuses?
IIRC, I left the epb off (think you can hold switch down and turn engine off so it doesn't auto apply, if that's enabled). Then just followed the guide and changed the parts by using a flat blade screwdriver through the hole in the disc/drum to wind the brake off and free the disc/drum. Then follow the guide for re-fitting and adjusting the pads before doing the brake bedding in procedure, which saw me driving round my local side roads applying the handbrake over and over again.
Easy enough to do, don't panic. If I can do it, you'll be fine and there's plenty of help on here if you did get stuck.
Good luck!

Although it's a while since I replaced the shoes (as opposed to simply adjusting them) , IIRC I left the fuse out until the brakes where fully reassembled / adjusted on both wheels.
You'll then need to run through the bedding in procedure.
Take your time and it's straight forward.I see no ships........

Thanks Gents!
I don't think I will be doing a EPB shoes replacement, rather cleaning only, as I barely used mine and I suspect they will be still in the good shape. Worried about the adjustment procedure as I was not sure when to re seat the fuse in the engine bay. I had bad experience with my old mechanic, as when he replaced rear discs, I got my shoes jammed inside both rotors, coming back home from his shop. Imagine rush hour traffic at highway speeds on NJ turnpike. Not fun!Back then, I did not know much about LR3 and had to resort to help from others. Nowadays, I am comfortable with swiping diffs among other things, but rear brake adjustment, somehow, was never my thing. Dealer always did the shoes adjustment right though.

Its very easy just replace the fuse after the adjustment. The only reason you remove the fuse is to prevent the park brake coming on accidentily when you have tye system apart.
The best method is to use a diagnistic machine to put the park brake into mounting mode this gives you the extra cable required when changing the shoes.
You say your shoes should be ok as you dont use the park brake much but in theory the shoes should never wear out as you only apply the park brake when your stopped.

While the shoes aren’t worn, there is a pivot arm on the rear that can sieze.
Enough cleaning oil etc will free it.
Not much fun remounting shoes though.

The shoes can delaminate through time especially if often driven in extremely wet/muddy conditions.

I did mine last summer, one tip I would suggest is getting the LR genuine shoe pins and clips, the ones that came with the Ferrodo shoes were rubbish, one snapped and the others are weak.
In fact just waiting for the snow to melt off a bit to fit the new pins and clips.
As to the fuse question, leave out until finished, then you'll definitely have no problems.D3 HSE 2.7 TDV6 named Calvin with him stuffed Tiger Hobbes sat in the back

Thank you very much for all the responses. I feel less stressed now, knowing, that EPB adjustment is no longer Black Magic skill. Is allen key adjustment really necessary ?

I dont think this allen key or strange mechanism is neccesary to touch i studied the mechanism and it mostly seem that it is there for some kind of stabelisation or anti rattling purpose and that it will seat itself properly after a couple of times use of the handbrake.
I think the most important is to free up the arm where the cable is attached as this gets stuck.
Adjustment is turn cog wheel adjusting nut all the way to full tight and back of 4-5 cogs, i do this all the times and works well.

The time has come for a rear brake replacement. I am starting a new job in NY and need my brakes in tiptop state. Lots of driving, braking and stopping. When I initially started this thread, I was convinced that I will replace both rotors and pads on the rear. I got away with adding just new brake pads in rear and new rotors and pads in the front.That alone gave me additional time needed to stall rear rotors replacement.
My only question is:
Do I really need to follow a full rear EPB bedding procedure if I am only replacing rotors and pads?
LR manual says I have to. And If so, is Bedding in procedure the same on LR3 as it is on LR4 per PowerfulUK video on YouTube ? Thank you.
