Volkswagen T5 Transporter - Handbrake Fail - Annj

Was on a slight incline and hadn't put van in gear when parked up. Got out of van and heard a very loud click, turned around and saw my van slowly rolling off. It damaged a residential wall, thankfully there was no one around and no one got injured. I put my details through letterbox of house, and have since had their wall repaired.

I took my van to my local garage to have it checked out. They checked the handbrake and said that one of the teeth on the ratchet was missing. I took a pic of it. I then took it to the local volkswagen dealer garage where I had had it serviced a few weeks ago. (Its only two years old, purchased on a five year lease package through Volkswagen) I left it with them to see if there was any other reason that the handbrake had failed other than me not leaving it in gear. When going back to collect They told me that they had tightened the brake cable as it seem a bit loose, but they never mentioned the missing tooth on ratchet. I hadn't told them that another garage had noticed this. When I did mention it to them, they said that they hadn't seen a missing tooth and from my pic, said it just looked like grease to them. They mentioned that I should have left it in gear. So basically, my own fault. When I was given back my van keys, they had left it on a particularly steep slope, but not in gear. I pointed it out to the mehcanic, he just shrugged his shoulders. After they tightened the handbrake cable, I notice when I used my van how it felt much better when engaging the break, it didn't have to be raised as high as before, which was very high. Basically, it feels like a complete new handbrake.

I wrote to Volkswagen to state my concerns about the handbrake and that I felt that the brake had not been engaging fully after the feel of it after their mechanic tightened the cable. They were slow to respond to my complaint and after no confirmation of receiving it for weeks, eventually got back to me to say that their mechanic said he only tweaked the brake cable and that in his opinion it was driver error by not leaving it in gear on a slope. I had only had the van serviced in this garage a few weeks ago. Even my wife has said what a difference to the operation of the handbrake, and that previously she had had to pull it almost vertical to get it to engage, but as she doesn't often drive the van, just thought it was normal for this type of van.

I was advised by the first garage who noticed the missing tooth to get a second opinion from an independant motor engineer. I did so and the report found the handbrake ratchet was indeed missing a tooth, and that the whole handbrake would have to be replaced.

Would the action of the handbrake not holding in place and failing on an incline cause the tooth on ratchet to break off? I'm wondering if I have reason to complain and ask for compensation to VW for a faulty handbrake or is it my fault for not leaving it in gear?

This used to be a common fault on VWs. Often when parked on a hill after the parking brake had been applied, and when the rear brake discs were hot, the vehicle would begin to roll as the discs cooled and contracted. It is essential that the rear brakes are correctly set up, with the handbrake slackened right off, and the handbrake cable adjustment is carried out last.

My new Transporter did this on the 2nd March this year, only been in for an inspection the previous week.

I now have a damaged bumper and two dented doors.

I'd say it is your fault. A handbrake cable can break, and if that happens then nothing will hold the vehicle unless it is in gear.

The highway code states that :

252

Parking on hills. If you park on a hill you should:

  • park close to the kerb and apply the handbrake firmly
  • select a forward gear and turn your steering wheel away from the kerb when facing uphill
  • select reverse gear and turn your steering wheel towards the kerb when facing downhill
  • use ‘park’ if your car has an automatic gearbox.

But the cable didn't snap. When I took it in after the incident they just tightened the cable, but when their head office asked them what they had done, they said they had just tweaked it, and not what they told me they had done. Also, they didn't notice the missing ratchet tooth. The first garage did and so did the independent mechanic, and it wasn't a hill, but a slight incline. I understand what you're saying though. I just want to ascertain as to whether there was maybe a fault with the handbrake that could've caused it to fail, and not just because I was parked on an incline.

To this day no vehicle manufacturer has produced a good parking brake with disc brakes. The only ones that are any good are those that have seperate drum for a parking brake. This arrangement also provides an additional emergency brake. As the above poster says, if you park your vehicle on a slope you should also leave it in gear. The parking brake alone may not be sufficient.

Quite Railroad, all three of our vehicles have the drum inside disc parking brake, the only downside of the design is that given how poor modern garage servicing has become that they tend to seize up through lack of lubrication, and correct adjustment means removal of the wheels to access in drum adjusters before touching the cable adjustment...this doesn't seem to compute any more.

Slipped a new set of rear discs/drums and pads on the Landcruiser yesterday, superb system, powerful reliable simple parking brake.

Volvos have known problems with this set up, but that appears to be down to poor quality OE brake shoes delaminating over time.

Over the past 30 years we have had probably 8 cars with rear dics and only one of those (a Kia Ceed) has had a drum handbrake within the hub.

The handbrake on all those cars has been absolutely fine. Never experienced any issues other than a reconditioned caliper at about 105,000 miles.

3 of our 4 current cars have rear discs, good handbrakes on all of them.

But all our cars are regularly maintained. Most cars that have issues are simply neglected.

Well I'm glad your vehicles all have good disc parking brakes, but whilst disc brakes may dissipate heat more efficiently which is better as a service brake, drums have the advantage of greater surface contact and a self-servo action. It is mechanically easier to pull apart than to push together. That is why drum brakes are better as parking brakes.

When testing the parking brake on the rollers during the MOT test drum parking brakes out-perform discs every time.
