EPB fault... of my making :-(
Hi all,
I had a very constructive Sunday changing the LRD3 disc and pads all round.. brilliant or so I thought.
Took it for a test drive and all worked fine and well until I got back on the drive and applied the park brake. Instead of the usual noise it make when engaging and dis-engaging, it instead may a loud squeal followed by a 'park brake fault - system not functional' on the dash and P blinking red. the back wheels also locked up and will not release..
I've now read many different threads and my logic is that I've inadvertently set the park brake shoes while in its' 'service' position where by the cables are extended to their furthest length instead of in the normal position.
My theory is that when it was then set to normal, and off the brakes are affectively rubbing...?
im hoping that I haven't done any long term damage to the EPB module...
I plan to reset the brake to service and see if the wheels free up, if they do then it seems like i'm on the right track... but if not... I might be in a pickle..
Can anyone offer any advise before I start as I don't want to do any more damage..?

Just an update to my saga with my epb which is all fixed now...
I managed to strip my epb module from underneath the motor while it was on ramps.
Disconnected drivers side hand brake cables and from the epb. Disconnected electric plug and two nuts holding epb to bracket (removed spare wheel for better access).
There was enough slack in the remaining HB cable and release cable to pull epb down between prop shaft and exhaust pipe.
Once done I was able to take out the epb drive gearbox and unscrew handbrake main and inner screws.
Disassembled motor drive to find a couple of teeth detached from the main gear (pictured below).
Ordered a replacement gear kit for £30 and started the awkward task of reassembly which was quite fiddley lying underneath the motor.. once all set up and shoes re assembled popped the fuse back in and hey presto worked first time and much better than previously... I’m extremely happy to say the least!
I took about 14 hours all in all (in between tea breaks) but saved the best part of £900,
would I recommend DIY.. only if you are mechanically competent and have the patients of a saint..!
Hope this helps somebody else out of trouble..
