In Reply to: Hard brake pedal feel posted by Tim Jones on June 29, 2001 at 13:32:51:
I haven't been driving my '02 for a while (just replaced the head gasket) and now I have a hard feeling at the brake pedal. It feels as if the power assist isn't working. If I start the car, the brake pedal does not get easier to push. The vacuum hose is hooked up to the manifold, and if I disconnect it from the assist I can feel that it is sucking like nobody's business.
Is there anything I should check before I replace the vacuum assist unit? I recently put dual 40's on and am wondering if that caused more vacuum and could have damaged the unit.
