Chaversdad, I’ve had a Scania and a Magnum fail on the parking brake, both 4x2s with park brake on drive axle only and they still have to meet the 12% of design weight criteria, both had a reline within a month of test and new brake chambers immediately prior and both failed, I got around the Magnum by having a brake test only before the test and when I knew it wouldn’t pass, by using a trailer with concrete blocks set up for 6 wheelers so it had a load of weight on it and it just scraped through, but that poxy Scania was a nightmare. I ended up speaking to an engineer I know at Scania HQ and he put me straight on how to get the design weight lowered to 40tons so it would pass, which it didI phoned up Cambridge (I was Eastern Traffic Area) and told them all about it, bloke there told me I’d done the right thing as I was moved straight to the top of the must visit list after the MOT fail
We have this a lot, I have to put new pads in one of mine every year to get it through, very annoying when it obviously isn’t a maintenance issue.
The really annoying thing is that it isn’t a level playing field, the plated weight should be the value you need to beat, not the design weight
