Thanks for the replies guys.
Flash, it's not much different, both on and off are pretty hard.
Mike, where is this guide? Otherwise the air has been pretty much discounted at this stage. Its acting more like the booster so I'm going to try get one (to a point its fine, after that its just hard). Cause the car still stops really well, its just the firm pedal.
Defective, the lines are not twisted or split cause each was tested. Brake fluid was replaced earlier today.
Ahh 33, I think I may just do that, thanks.
