Stiff brakes

[wangboy925]

Ok, I just finished installing my intake manifold and now the brakes are extremly stiff. It feels like Im gonna destroy the brake petal if I push any harder in order to brake the car. Im pretty sure the break booster line connected to the manifold is not leaking and the manifold is getting sufficient vacuum (-20 mmhg) at idle. Now do I have to bleed the brakes to fix this problem?

You need to double check your booster hose from the manifold to the brake booster. What is going on is that you are not getting any vacuum to the booster and you basically have manual brakes. Also make sure the line isnt pinched or twisted. Hope this helps. Travis
