My 2012 plus 4 stops very well on the road
When the MOT man puts it on his tester however the front brakes are always quite imbalanced, there’s about 30% difference between left and right. Yet on the road it pulls up straight and true.
My yearly maintenance involves removing both calipers from the hubs and gently easing each piston in and out and applying a tiny amount of rubber lube to the seals, cleaning off all residue. There’s no sticky pistons, no deformed discs and no contaminated pads. There’s no air in the calipers and all flexible pipes look like new.
I’m soon to start my annual maintenance process and wondered if anyone might have other suggestions I could add to my jobs list?
Thanks
Gary
Given your comments the only thought I have is the calibration of his tester or the grip of each of your tyres on the rollers. As suggested try another test station.
