Re: Renault Master Project - Brake compensator

I take it you are referring to the load compensator. If so it is to reduce the risk of the rear wheels locking up during braking and causing the vehicle to go out of control. It also helps to proprotion the brake pressure between th front and rear brakes increasing braking efficiency. If the vehicle had such a compensator when new then the MOT examiners should have known one should be fitted. If that is the case then it down to shoddy MOT testing.

Not all testing stations have the correct kit for such testing so many just ignore this aspect. Where I live the all testing station have a special hydraulic load application jack.

Such compensators were done away with on many vehicles when ABS was introduced.
