Re: It got hard


Start the truck and put it in gear... sit there with your foot on the brake and let it idle (still in gear) if the engine starts to run rough or tries to stall it's a sure thing the boosters going bad. It's at least worth a check before replacing the booster anyway.

The brakes seemed to have a very short delay when mine was bad. When I pushed the pedal it was like they didn't responde right away.. just a fraction of a second, but it was there. They also made a sort of "airy" sound... don't really know how to describe it.... anyway.. good luck.
