Question about 1999 Pontiac Grand Am GT

1 Answer

Is the brake booster going out?

I hear a "whoosing" sound everytime I press the brakes and there is a lot of pedal travel. I have changed the front pads, adjusted the back shoes, changed the master cylinder, bench bled the master cylinder, bled the lines at the cylinder, bled the abs pack and bled all four wheels.

Let me know what you find out. I get the same whoosh/pedal travel, and at this point have NO braking at all. I am also losing fluid nearly as fast as I can put it in if I use the brakes, but I can't find where it's coming out. I even drove on clean snow and don't see any fluid tracks...

Oddly enough if you are going to do it yourself, gmpartsdirect seems to have the best prices for OEM parts.

I am assuming that my rusted/pitted brake lines have failed me. Aaahhh the old money pit.

Vacuum brake booster toyota sequoia 1984. Brake Dealer completed diagnostic test showing codes C1223,1247,and 1310. Conclusion the booster needs replacement. Must I? (about $1,000). Safety issue???


Toyota Sequoia's had a lot of problems abs wise> #1 clear codes with a factory software scanner. then drive it to see what returns. I can not see a brake booster setting 3 codes that are ABS/VSC problems #2 how does the brake pedal feel If it is high and hard pedal then the booster is bad if the engine speeds rise as pedal is depress and you hear escaping air the booster is bad. #3 ABS/VSC are supplemental systems to the normal braking soit will take longer to stop and a possible skid could occur. but you will stop leave more traveling space you should be fine.

Brake pedal hard to press has a hissing sound


Check the vaccume line going to the brake booster. BUT if you can hear a hissing sound from inside and the pedal is hard to press more than likely your going to need a new brake booster and a new brake master cylinder.

Why do i hear air when i press the brake pedal


well, you don't really hear air when you press the brake pedal. You might hear hydraulic fluid going through the valves in the master cylinder, that sounds like air flowing through a vent. But, I assure you, it is not air.

One can press and pump on the pedal when the car is off and hear the 'rush' of fluid which sounds kind of like air rushing out of an inner tube.

It's a common mistake to believe a rush of air is being heard when pushing on the brake pedal.

I have excessive brake travel, and a hard time 98 chevy blazer


Two issues...
The brake booster has a ruptured diaphragm. Replace the booster.
It is located under the hood between the brake master cylinder and the firewall.

Your master cylinder may be leaking fluid internally past the plunger.
Have it examined when you change the booster.

Power brakes not working


No such thing as vacuum lines to the master cylinder. You do have a vacuum line on the brake booster (power assist). When you step on the pedal do you hear a whoosing sound down by your pedal. This is a leaking Booster. Needs replacement.

When you step on the brake does the engine rpm change. This is a leaking check valve (one way air valve).
