Hi everyone! I recently started to replace my vacuum hoses and I got stuck at the brake vacuum hose. There is a hose at the back off the manifold that goes in to a check valve. The check valve has 2 plugs (one for EGR which splits with one for throttle body and one for.... something with 3 plugs ). The other end of the check valve in all the vacuum diagrams should have a hose that goes to the brake servo. My current setup has a check valve that is blocked at the end where the vacuum line for brake servo should go. Does the ABS TEVES MARK 2 has a brake servo or is just integrated in the pump? In this case does it have a vacuum line? The check valve in no. 11 https://volkswagen.7zap.com/en/rdw/corrado/cor/1993-76/1/133-36040/ My car is LHD Thanks guys, any answer is helpful!
