Default solid brake pedal

brake pedal goes soild when i accelerate, but as soon as i let off the gas its fine again...

so its almost like the servo is becoming pressurised when im on boost. do they have a one way valve to stop this?

or the servo is not holding vacuum but it can become overcome on over run?

leaky pipe?

i have not had alook at it yet, but i will when i get a few mins today.


any idears??

cheers

Yes, there should be a one way valve giving you about 5 pumps of the brake pedal before you loose all assistance.

I had similar when I fitted Samco hose as the brake servo pipe did not have a one way valve in. Fitted the original and problem solved.
