hey folks,

on my beloved 94 mondeo i seem to have an occasional brake problem which has been on and off for about a year and a half now. lately it�´s been getting more frequently, though, and at speeds in the triple digits this ain�´t no fun anymore.

usually the brake pedal works fine, but sometimes it feels hard and hardly slows down the car. it kinda feels like the power of the power brakes is missing. is this a problem of the master cylinder or rather of the brake booster? brake pads in front are 75%, front rotors are new (1000 miles) and the rear brake shoes are around 50%, or a tad less.

the brake system seems not to leak and the power brake sees to work normal (under regular conditions). �´

any advice or experience?

thanks, clemens
