Hi,

I appreciate that this has been discussed many times before but would welcome any advice on this please.

I have owned the car (2007 CRD) for a couple of years but the parking brake never seems to work that well. I understand the previous owner of 7 years hardly used the parking brake. I have the MOT soon and am not sure it will pass on the parking brake.

Most of the time when I tread on the parking brake pedal, it goes 'clunk' in two or three positions and the pedal goes a good distance towards the floor.

If I tread really hard it does hold the car to some degree but certainly not on any kind of hill.

Should I be hearing a 'clunk' when I tread on the pedal?
I have read about the actuators and adjusting the parking brake in the rear hub. What are the things I should be doing with the parking brake in regard to regular servicing?

Many thanks.

Definitely the actuators. They seize and cause that clunk. Take the brakes apart, clean or replace the actuators, copper grease them. Then reassemble and adjust

There's a reasonable video here: Link though you don't have to take the bearing off as explained in the video.

Adjustment process for the parking brake here: Link

Excellent, many thanks for the further info, that is really helpful.

I have read in the forums that some owners do seem to have a smooth pedal action while others have had a ratchet type clicking action, which I assumed meant there were 2 different types of parking brake mechanism.

Mine definitely doesn't work well though, it does sometimes if I stand really hard on the pedal, but the click/clunk makes me feel slightly nervous!

I've looked at the video and it looks like it may be quite challenging for me, but may have a go in a couple of weeks before the MOT. When you say no need to remove the bearing, do you mean the section of video where he removes the hub? (from around 6:10 on the video where he removes the rotor/disc up to 9:00)

I see they sell a service kit in the Custom Shop, so I guess it may be worth getting one of these:


......actually, if I do not need to do the section from 6:10 to 9:00 it doesn't look too difficult.

Thanks again.

I've had my car from new in 2006, but never had an issue with the parking brake - no clicks when operating, other than a single click when releasing.
However, I've never been impressed with its efficiency and always surprised when it gets through the MOT without comment.
