please could someone help, i have a 1974 2002 auto which i have owned for the last two years i do less than 2000 miles a year in it and i drive it every 10 to 14 days the problem is I went to use the brakes and the pedal went straight down to the floor with vigours pumping i was able to stop the car, i thought air was getting into the system so i change all hoses fitted a new master cylinder kit all new brake fluid this seemed to work and was ok for the first 200 miles, then the problem reoccured, only difference this time was, pumping the brakes this time i managed to regain pressure in the system and i was able to drive home, albeit very slowly. please can any one tell me if they have had a fault like this how to rectify it or what i should be looking at next. any advice would be much appreciated
