  • good brake testing procedure???

    Hi gang, what's up? Don't know if you can help me..i recently had my rotors and pads changed. The car does brake okay, but probably not as good as when i had the stock equipment. I came across this check-list on brake testing...does this make sense for a test?

    Functional test
    1. with engine stopped,depress the pedal hard and hold that pressure for 15 seconds.If the pedal sinks,the master cylinder,brake line or a caliper is faulty.
    2.start the engine with the pedal depressed.If the pedal sinks slightly,the vacuum booster is working.If the pedal height does not vary,the booster or check valve is faulty.

    I treid this out, i did it twice... both times i noticed when holding the pedal down that it was slowly sinking and when i turned the key to the "on" position the pedal dropped (almost to the ground). On the second time though, when releasing pedal, i heard an air, "wooshing"sound all the way until the pedal came back up...can this mean anything?? thanks

      Hey MArius...what's up? when i tried out this theory...the wooshing happened on the second time when i released the pedal....

      when i'm usually driving and press the pedal i can hear a wooshing sound,when i release...i don't really hear anything...
      isn't it normal to make SOME sound when you press down on the pedal?
      thanks

          update...well i noticed tonight when i was leaving work, i started the car, was idling...i pressed the pedal hard about 4-5 times..it felt a little soft..after the 5th time, i heard a "buzzing" noise from when it traveled down, stopped, and buzzed again as i released the pedal...master? booster? any help would be great..thanks

            The buzing its a vacum pump in the engine bay helps to keep a certain vacum pressure , by pressing so many times the vacum pressure was to low so the pump turn on to ensure proper vacum ... come by the dealer will go road test toghter , it seems u create your own problems wich dont exist !
