Ok guys here goes,
Brakes were working spot on, then at one intersection miles from home brake pedal went to floor after stopping,
I believe its called brake sink...
And its been that way ever since, 90k on the clock.
All Calipers checked ( all good)
All lines checked nothing found
No vacuum or fluid leaks found
Replaced master cyl.
I mean its the brakes , how hard can it be, 3 mechanics later no resolve,
Pedal still goes to the floor after she stops.
The only thing noted was after 3 containers of brake fluid and much bleeding , the last thing we tried was to bleed the brakes while running. To our surprise some air came out the right front. The pedal still sinks but not as fast.
So I am wondering if there is a special bleed process? or any ideas, because at this stage I may drive it in a lake or tree.
thanks collective wisdom...
