hi, i have brake fade down to half pedal then a reasonable pedal, which only gives poor brake, i have changed the master cylinder 3 times, and bled the master cylinder according to the manual, i have bled the brakes 4 times, the first time useing sequence left rear/ right rear/ left front/ right front, the second time i started in reverse, right front/ left rear/ left front/ right rear, the last times of bleed i dissabled the abs . the abs would appear to be ok, the servo unit appears ok, it goes down when engine is started ok, new pads have been fitted all round, i have checked for any air leaks. i am certain that there is no air left in the pipes, hope you can help as it has beat me , incidentally i have been in the motor trade for over 40yrs on the body side, and only occasionally on the mechanical, based in nottingham uk my car is right hand drive
