My brake booster sucks! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

As the title says, my brake booster sucks, as in sucks all of my vacuum. When I push the brake pedal, you can hear vacuum leakdown, and the idle kicks up a bit. The brakes work fine. Should I just replace the booster or is there a rebuild kit that would be halfway easy to install?

It may be hooked into the wrong port, i'm not sure which is correct, though

Replace-internal leak.

Sounds like it's bad.You can get a vacuum tester and check but be aware one of the BB members had this problem and the vac leak caused him to run lean and overheat,I believe he wound up having to replace the engine.
