MK1 braking system
when i purchased the car, i had SOME braking power, it sat for 10 years but i did actually have some.
fast forward to now
i removed the master cylinder and purchased a new unit
i removed the brake booster and painted it
I bench bled the master and reinstalled both units to the firewall
When the car is OFF, i can build pressure in the pedal to where it feels somewhat firm, but as soon as i turn the car on, the pedal goes all the way to the floor very loose right away, no pressure at all. while running, if i pump the brakes as fast as i can i get a hint of pressure built up, but as soon as i stop pumping for a second it will go back to the floor with zero effort.
I went and replaced both rear wheel cylinders and made sure everything was nice and tight.
Bled the entire system from right rear- left rear- right front - left front.
this has been a constant headache because ive been fighting to get on the road for weeks and this is whats holding me up. does anybody have an idea on where to look?
