Year of Manufacture *: 2005
( Optional ) Engine Code or CC: BKC
Have this Octavia 1.9 TDI with a slowly sinking brake pedal with the engine running.
Not spongey, but slowly sinking when held with a medium pressure, to within about 2 inches from the floor.
The brakes work fine, pull up well, ABS works, good servo assistance , no codes or warning lights and no fluid leaks.
Master cylinder has been replaced with genuine item and the problem, if anything, seems a little worse!
Brakes have been bled to within an inch of their life, manually, pressure bled and via the diagnostic machine.
All the pads and calipers have been dismantled, cleaned, checked and reassembled, the ABS unit has been removed and bypassed to eliminate internal leaks, and still the pedal sinks!
Any thoughts please?
Yours frustratingly
Colin.
