Re: Scenic II handbrake module

I have a similar problem with the handbrake. The dash service light is on and it beeps sometimes and puts up the nagging message. I changed the disks and pads some time ago. Used a brake rewind tool and made up a special tool to jam/stretch the handbrake cable to allow some more cable to be released from the main unit.
All worked well but a while after that the brakes started to bind and the warning light appeared. I think this is due to the cables, the brake calipers are ok. I tried forcing some lubricants up the cables with limited success. I think I am going to have to change the brake controller.

I am in the Edinburgh area and don't trust the main dealers from past experience.

1. Did you get your unit from a main dealer?
2. Who/where was the independent garage that reprogrammed.
3. Do you know if the cables can be replaced or from your look inside the unit can they be disengaged to facilitate lubricating the cables?

MOT due very soon so have to get this fixed. I think the dash warning is now an MOT failure.

Any photos of inside the control unit?

Any help much appreciated……

Re: Scenic II handbrake module

To answer your questions -

Yes the unit was purchased from the main dealer - AC in Stirling.

The indy I used was SWR in Stirling - one of the two guys running the show is ex-Renault. I have their number if you need it.

I have heard of people replacing these cables, but I don't think they are a standard part. I'm sure they had them made up as one off items. Sorry I don't know where.

I'll have a look to see if I have any pics of the inside of the unit.

Edit: sorry no pics of the internals , but here's one of the unit removed with the screws you'll need to remove to gain access to the insides ( in white ) and where the handbrake cables attach ( in red )

Smile Re: Scenic II handbrake module

Handbrake now fixed.(£530) After finding a source for the unit and reasonable price for programming I ended up having to go to a dealer near Dunfermline as I needed the car fixed quickly.
As it turned out, it was around £65 quid more that it would have been to do it myself and get it programmed.
Anyway I have retained the old unit which I will strip down and take photos of it.
My main problem was the inner cables were jamming due to a rusted and broken outer cable on both sides. The inner cable has a clear plastic cover that had wrinkled and peeled causing it to jam at the end part of the outer cable that is held by the C-clip. This prevented the cable releasing fully as the outer cable moved away from the calliper fixing and the inner cable didn't move. One of the two rubber shock mounts that hold the main unit to the plastic sub frame was also broken. this also allowed the unit to move slightly..
I did strip down the unit, it is easy enough to remove it (remove the spare wheel to make it easier still). Also removing the actuator arm on the calliper to make removing and replacing the cable easy. (Splined shaft)
With the unit cover removed, the cable end caps unscrew allowing you to lubricate the inner cable, whilst moving the cable back and forth so that the lubricant travels down the inner section to the nipple end.
My mistake was that after removing the damaged inner plastic cover, I then cleaned up the broken cable ends...and removed the broken part from inside the cable end termination that the cable should be attached to.
This resulted in shortening the cables by over 10 mm each side. After replacing the unit it worked smoothly ... until it started making a nasty grinding noise, I'm assuming the screw in the motor assembly was screwing in too far and eventually jammed. The unit stopped working. (remember to use silicon gasket sealant when refitting the cover)
I should have fabricated a spacer to put on the end of the cable to compensate for the short cable. Hindsight is a great thing......
Once I open up the unit I will find out what went wrong.
Many thanks for all the info supplied by the Forum.

Angry Re: Scenic II handbrake module

Hi all, thought you all might like to know that the cables come off on Scenic2 HB module, its a doddle remove cover, six screws, watch for gasket, small clip holding plastic sleve on cable lever up gently, slide sleve off, unscrew large plastic retaining round nut! cable now off, it's held on by a ball & claw attachment, plastic sleve stops it from comming off.
Dont forget to remove end from calliper first.
This then allows you to LUBRICATE cable.
I only found out after paying for new unit fitted,,,

Re: Scenic II handbrake module

Can anyone tell me what each of the thick wires in the plug to the handrake module does?

I want to know which one requires +12V in order to activate the mechanism.
