Hi thanks for help my car is earlier than this model affected and it has never lost any fluid and there are no visible leaks anywhere I read in haynes manual that the system sometimes requires pressure bleeding to fully remove air so far i have only used conventional method

I had a similar problem with my '96 car which has the later Teeves system.
Basically the problem was purging air from the ABS unit.
I was successful in the end but it took several goes.
I found the old method of pumping the pedal then standing on it while an assistant let the pressure go from each beed nipple in turn eventually worked.
The air seems to migrate to the rear circuit, it took about three goes to get it out. Once a week for about 3 weeks.
Good Luck!
