If you don't have any problems with the idleing and you can't hear a hissing noise coming from the hose, then the hose is OK.

Have you tried to get the Booster at the Junk Yard?? There are various models that use the same type of Booster. The price is only a fraccion of the brand new one and the hose is includded.

Good Luck!! Don't forget to rate this post!!

Anti lock has nothing to do with it. the brakes operate without ABS. run the motor then turn it off. pull the vacume hose off the power booster and listen for a suction sound. if none. plug it back and start the car. pull the hose and put your thumb on it. it should ****. the booster depends on vacume to work. If you have vacume to the booster and the pedal is hard, change the booster.(scrap yard)

If the rear are drum brakes, have you pulled the drums to inspect the rear brakes?

I drive a 1995 Cadillac Seville SLS. My brakes have become unresponsive. they feel stiff, and I have to put both feet on the brakes and stand on it to slow the vehicle. pressing the brakes is...


I wouldn't install a used brake booster,but you could

You don't need instructions & a list of tools

If you & your friend together need that,you shouldn't
be doing that job

You will find 4 nuts in plain site, on the firewall holding it on.
You know enough to remove the brake tubing on the master
& can unbolt it ,to swap to different booster. Not sure
you can leave the brake lines in place until you try removing
the booster.

Before you do all that ,remove & check out the vacuum
check valve on the booster with the hose going to it

They are a somewhat common replaced item. You may
only get a couple in your life time,but they do fail somewhere
every day.

How do i change my break booster in my 95' mercury tracer? i have problems with my car when im at a stop and when i take off from that stop it sputters but if im at a stop and i put the car in nuetral it...


IM NOT SURE WHAT THE PROBLEM IS BUT IT'S "NOT" YOUR BOOSTER. IF IT WAS YOUR BRAKES WOULD LACK POWER. MORE PRESSURE WOULD BE REQUIRED. YOU'D FEEL IT IN THE BRAKES IT WOULDN'T MAKE THE CAR SPUTTER IN DRIVE AND NOT IN NEUTRAL. SAVE MONEY IT'S NOT YOUR BOOSTER.

Brake light comes on, add brake fluid. what is the cause?


One of the reasons is because you have a leak somewhere. Try following your brake lines starting from your brake power booster and work your way back making sure all of your connections are dry and tight. Another place to look is in on your caliber piston or if you have rear drum brakes, take off your drum and look at your brake boosters. Both have rubber seals and can leak. If all is good then look into your power brake booster. Hope this helps!

99 Olds silhoutte stalls when you apply on the breaks.


Sounds like your power brake booster is bad internally. That booster works off of engine vacuum and when you have a vacuum leak your car will run very badly. The booster uses engine vacuum to help push your brakes and when your booster doesn't work your brakes will be almost very hard to push. The car will stop but everything just feels like something isn't right. There is a tube going to your brake booster from the engine. One way to check for a bad brake booster is to remove that tube from the brake booster, pinch or seal off the end of that tube with something other than your hand. Start the car. The car should idle WAY too high at this point because of the "meantime fix". If you were to drive the car with that tube clamped off it would run better but your brakes would still be hard to push. The woosh you hear when you press the brakes is a sign of a broken diaphram inside the brake booster and when you hear that the engine is loosing vacuum and will run very badly at that point as noted by your stalls when you apply the brakes. I understand the no money part of your problem. If it were me, I would put the tube back on the brake booster and then I would take a small set of locking pliers and lock the clamp of the pliers across that tube and that will stop the brake booster from loosing vacuum but would still allow you to drive without stalling but be aware the brakes will still be VERY hard to push. As I said before. they will work but you will have to apply more pressure to the peddle because there will be no power assist function going to your brakes.

Please be aware, try this temp fix at your own risk. The true fix for your problem is to replace the brake booster.

Much good luck!
