Check for leaks in cabin at firewall and into the booster itself.
Hello All,
Without there being any fluid loss - what could cause the brakes not to work after a vehicle has been left sitting idle for an extended period of time - months/years? The vehicle has ABS.
Prior to a non-vehicle related accident, the previous owner used the car their daily driver - so it had fully functioning brakes. When I bought the vehicle it had sat for a while and it brakes did not work. The brake reservoir is full and there is no sign of fluid leaking from each wheel. There are no signs of leaks around the master cylinder either. However, when stepped on the brake pedal just fades down to the floor and there is no braking force.
Is it a problem with the master cylinder?
Would the brakes still function if the brake booster was defective?
Is it a problem with both the master cylinder and the booster?
Could it be a problem with the ABS module?
Or could it be "All of the Above"
What steps or checks could I do to isolate and identify the possible cause?
I have only been able to find master cylinder overhaul/rebuild kits for Non-ABS master cylinders. Does anyone know a source of rebuild kits for an ABS master cylinder?
The vehicle's build date is May 1996.
My apologies for the string of questions.
Kind regards
Lionel
