    bad braking

    when I am going moderatly fast, and then brake hard, it feels like my booster fails. Like when you shut your car off and coast to a stop, and your power steering is off, so is your brake booster. That's the feeling I get when I brake hard. I was told it was a vaccuum leak from the brake booster line. I have a link to a picture of what it supposedly is.

    That's the check valve on the red box , the brake booster would be the round thing where the master cylinder is attached to.

      I know. I was told that the check valve was leaking. Is that a common problem? Or is that even the problem?

        Those could do failure sometimes. Try replacing it.

          Aright I'll check the dealer for a price on that. It's getting worse, like just now on the way home i was going maybe 10 mph down a hill and they went again. My auto teacher suggested a leak on the...??primary...secondary??...seal of the master cylinder. One leaks internally so you can't see a loss of fluid, and the other leaks externally. I keep mixing them up

            Could be the master clyinder or the booster itself. Just from my experience, I have never seen the check valve go bad. Possible.

              If your your brakes are hard and it stop slowly , it's your brake booster.

              If your brake pedal goes all the way down then it's your master cylinder..

                it's called a "hard pedal" and is related to the booster. you can probably hear it hissing if you listen closely.

                have you had a bad m/c in the recent past? they can leak into the booster and eat it up from inside out.

                  I wouldn't know fizzbob, I bought the car last year and just got around to registering it, so all the problems are brand new to me. I'll rip the m/c apart tomorrow in class and check it out.

                    don't do that, may just ruin a good m/c

                    with the car idling, listen for a vacuum leak (hiss) outside of the car and inside up under the dash.

                    normally, these boosters go bad and make a noise under the dash. sounds like it's coming from the rod that goes through the firewall and attaches to the pedal.

                        yep, I hit the brakes and I hear a hissing under the dash, above my foot. So replacing the booster...funnnn....haha don't ya love saving up for a project and having "fun" things like a blown radiator, a speeding ticket and a bad brake booster take all that saved money from you?
