Anyone had this problem before....Rear brakes lights including high level light fail to come on under gentle braking (enough that you would expect the lights to come on). I only realised something was up when a very pleasant chap nearly buried his Merc sprinter van in my boot and gestured that I may have been in the wrong. At least thats what I think he was trying to say as I told him to f**k off. I have to really stamp on the brakes for them to work, and before they start to behave themselves. If I then go back to gentle braking they stop working again. Another hard stamp and all the brake lights light up like Blackpool tower (not quite). Could it be a dirty contact somewhere? Anyone a pro when it comes to the braking system? I'm considering left foot braking from now on and preparing my insurance company for the inevitable claim.
