    Comments about Wearever Unloaded Vacuum Power Brake Booster - Domestic:

    Old original brake booster was constantly hissing and getting hard to push down on. Replacing it with remanufactured one from Advanced Auto Parts fixed the hissing problem and has worked ever since. Wasn't to hard to install, hardest part is moving the master clyinder out of the way without kinking the brake lines when bending them to move the master clyinder. Bolts are tricky inside the cab under the dash if you don't have a socket extension. Once bolted up, takes a little bit before the booster build up enough pressure to have "pedal" and stop like normal, but once it does it's perfectly fine, brakes nice now.
