The document

My report is in my gallery.

Not as polished or complete as I intended, but I will work on it.

Also the photos need annotating better.

BUT screaming EPBs ARE wrecking themselves; every howl is damage done. This story must be told!!! Etc., Etc..

A dismal tale of design failure.......

Read and weep. Prepare to do battle with LR and Herr Kuster...

PS there are 150+ photos on Flickr - I need a Flickr expert to help me through copy proofing them and making them accessible to a limited audience...

Wow! That is an A1+ example of a report, clear concise and at an excellent level of detail Thumbs Up
I like that a lot!
That really brings some hope that the unit can be given a lifetime that will approach that of the car, rather than for the life of the warranty. I look forwards to hearing about the potential costs of the brass upgrade kit; this failure is now very obviously a 'when' rather than an 'if'.

Thank you Andrew Bow down Bow down Bow down Bow down

Brilliant report Andrew. Bow down Some LR BS dismantled there by the looks of it. Copy to LR Customer Services?

Brilliant, Thank you Bow down

All we need to do now is figure out how to apply enough pressure on Landrover to accept the consequences of this failure beyond the 3yr point - or in some cases before the end of warranty.

As my car rapidly approaches the end of warranty, I intend to note my concerns (in the form of a letter) over the inadequacy of design of EPB & EGR's, neither of which appear to be fit for purpose.

Very impressive, and no doubt LR will also read it. Thumbs Up

Excellent work Andrew, very interesting.

Must be worth sending a copy of the draft to the manufacturer, informing them that you have also copied LR (ie their customer!). It would be in their interest to respond before your report finds its way too far around the www!

Brillant work Andrew. I have just had a new unit fitted but am told that the part number has changed. I wondered what the part number of the one you disected was?

I have asked for my old one back , the garage is keeping for me but I have not picked it up. When I do so I will also ask for the number of the one they fitted.

Thank you all!

Certainly part numbers of replacement units will be important - if there is a design change we might go for a Class Action???

Further dissection of other units will also be very important - I have a supposed healthy (early) one on the way...

Then a plan of campaign... Which LR magazine do we reckon? I noticed LROI did something recently, but my brother nicked the copy before I read it!! (It was his... Sad )

I think Küster should be informed; maybe I SHOULD do that next...

Very good report.

I have had for sometime screamers on and off until recently, when I adjusted my brake shoes to the '6 clicks back' method instead of the widley publicised '8-12 clicks'. Yes I realise I am running the risk of having the shoes binding on slightly but I checked hub temperatures after the adjustment. Anyway, getting off the point a bit but this to me shows another inherent problem in the system; the inability of the EPB to drag enough cable in. In my case I assume the splined shaft was threading the brake cables towards each other, but instead of stopping when the cable went taught enough to satisfy the strain gauge it was too loose and ended up reaching the 'draw in' limit, thus provoking the overload clutch into operation before the cables were tensioned enough.

Anyway, to prove the EPB is not fit for purpose it has to be shown there is a design flaw, of which Andrew has pointed out a few. Looking at the E-clip retaining problem alone, can we not find technical data regarding the plastics properties in order to consider what loads that 1mm bit of flange should be capable of holding over an expected 10-15 years of life? If it can be proved to be inadequate (or in the UK legal system of civil cases - probably inadequate) then we may have good grounds for legal action over LR.

Excellent piece of investigation and report. Just a bit scary that the inside of the EPB module looks to have been made from spare parts from a kid's toy... I just can't believe how much plastic you found in there!
