Loosing brake pedal pressure when on boost??
Hi all
As above when my car comes on boost then try and brake there seems to be no pressure in the pedal or it seems to go rock hard and is stupidly dangerous when needing to brake. Spec is....
03 blobeye wrx
Recently fitted new turbo and full exhaust system
Also reversed the inlet manifold
Relocated header tank
Do you think any of these could be a factor ??
As it seemed ok before the mods took place any help and suggestions welcome
Thanks

Yes I did mate I think that may be the problem as I've just found the return valve in an old pipe I took off. Thanks for the help!!!! On the other hand and maybe stupid but which way does it go back in??
Thanks
Thanks

Brake servo operates on a vacuum, so at a guess I would say air should pass FROM the brake servo out, but not TO the brake servo, if that makes sense - that will maintain the vacuum level
