It works... but not as well as OEM

Comments about Wearever Unloaded Vacuum Power Brake Booster - Domestic:

The install is easy, you do not need to disconnect the hydraulic lines to replace the booster in a 2005 escape/tribute/mariner v6, i cant comment on other years.

One important note is that you must remove the brake and cruise switch before removing the booster rod. If you do not when you remove the rod the brake pedal assembly will push the switch plungers in further, and they will "relearn" the brake released position, so once you put the rod back on your brake lights might be stuck on or your cruise might not work. Mine works fine since i did this, but even if you do there is a small chance the pedal is bit lower then before, if so you will need to either shim the assembly like the other reviewer, or buy new switches that will learn the new lower position, there is no way to reset the switch once it has set itself to a higher position.

Finally onto the performance of the actual booster, it did fix my original leaking/whistling booster for $38 after a discount code, so that's a plus. The negative is it only seems to provide about 70-80% of the original boosters power, so i have to push a little harder, i would still call it a "normal" brake feel, but it is just different then before. It took about a month, but i am used to it and don't notice anymore, except for at long lights. It also sometimes has a "sticky" feeling when pushing it off its resting spot, like the internal rubber parts are clinging together or to other steel parts. Not bad, just something i noticed. It would never pass an OEM test due to these issues, but vs. the $150 for a new OEM booster, ill live with it. If i had to redo things i would have tried to find a low mileage booster from a junkyard first.

Comments about Wearever Unloaded Vacuum Power Brake Booster - Domestic:

Works fine, with a small issue.

The rod connecting to the brake pedal was a bit too short, by about 1/8th inch. Which means the brake pedal is about 1/8th inch lower than it's supposed to be. Which means the buttons/switches behind the brake pedal constantly believe the brake pedal is depressed, leaving your brake lights on constantly and disabling cruise control and allowing you to shift into reverse without depressing the brake.

I taped little ceiling fan weights to "shim" the buttons for it to work properly. I've read about other people have the same issue, and glueing coins there. As far as I could tell, the rod was not adjustable, nor was the brake pedal for my vehicle. (Ford Escape 2005 V6 4-disc brakes)

Doesn't leak, so original problem solved. Has worked fine for 2 weeks. Can't comment on the longevity of the part.

Isn't the prettiest thing, obviously a remanufactured part.

The instructions included are generic, but useful. Although they did not cover my specific issue.

I guess if I had to do it again, I'd have spent a bit more, and tried a new part.(Motorcraft BRB31?) I don't like the idea of having to glue/tape anything to my car, even if it functions the same and is not visible.

  • Q:

    Can I use the Power Brake Booster for the 2005 2.3l 2WD 4disc brake power booster on a car with only 2discs? I'm assuming it just has more power to it and it's half the price.

      I recommend that you purchase a brake booster that is made for your vehicle.
