Just had MOT (2007 LWB Relay ) though it passed it stated"inefficient parking brake".Now I have tried to improve it by new disc/drums/linings etc d but not a lot of improvement! Is this a week point on these vans?
On my last MoT and service, although it passed there was an advisory about the handbrake being inefficient. On taking the wheels off (Dave always does that) to check apparently the disc pads fell to bits and all had to be replaced - basically due to the rear brakes hardly ever having to work! DBK's suggestion helps to "work" the rear brakes and break up the glaze that unused brake pads build up.
The parking brake is completely separate to the disc brakes and is a top hat drum brake system with cable operated shoes in the central drum of the rear brake discs, at least on a panel van.
Correct adjustment is critical and adjustments have to be made in the correct sequence starting with shoe clearance at the drums and following through from the rear to front cable adjustment points.
Lazy mechanics who only adjust the cable tension is where it all starts to go wrong and result in poor performance. Properly set up they should be more than capable.
Occasionally lightly applying the handbrake whilst moving very slowly will help to clean off any dust or light corrosion in the drums, but there shouldn't really be any appreciable wear because, apart from the roller test for the MOT the brake should only be set when the vehicle is stationary in normal use.
I was wondering that.... Its either efficient enough to pass or it isn't.If it passed then the handbrake wasn't inefficient according to MOT regs so why would they put that presumably as an advisory.
I have a 2011 model and the handbrake is not the best, have to pull it on hard and always leave it in gear on a slope.
