The car is now being used regularly for the first time in 3 years so everything is starting to be used again. Before I put the car in for the MOT check I made sure all the brake sliders were working, the calipers were free and the pads had plenty of "meat" on them.
Over the last couple of days,I am not driving the car fast, I have noticed that the brakes require a lot of effort to make the car stop. Am I right to assume that the accumulator has failed?
