Question type: Maintenance & Repair

Hi i recently changed my front calipers and
pads both of them left and right and when i
hit the petal i still hear hissing i checked all
the vacuum lines they are good so what
could it be

1 Answer


If you hear the hiss inside the cab then the vacuum booster has a seal that is failing, you will have to replace the vacuum booster, but before you run down and get one check under the master cylinder right where it bolts onto the booster and look for a brake fluid leak where they join together, if you find a small leak there then it would be a good idea to get the entire unit and replace the entire assembly.
