Hi Folk's this is really a follow-on from me asking what the Brake nipple sizes was for the M-Class , i came home from Work Friday the 22nd and the foot brake was feeling spongy,and was sinking away ? so i was convinced it would be the Brake Master cylinder, i ordered a replacement, turned up yesterday, so fitted it then more rain, so decided today i would bleed the system through,well the pedal is hard but there does not seem to be any Servo Assistance now, as there was prior to this happening anybody any ideas

Many Thank's Kevin
