Re: Renault Master MOT failure
Don't take this as gospel but I think as well as the individual brake readings for pass/fail both results are also added together and an aggregate figure is obtained for an overall pass/fail result. This would explain why the wheel with the high reading this time has still resulted in a 'fail'.
I think you will also find the imbalance between the two readings may also be a factor.
