What would cause a hissing noise to come from the brake pedal on a 1990 ranger when it is pressed down to the floor and the brakes barely work?
Vacuum brake booster is defective or the hose going to the booster is leaking.
Mazda B2300 1997 the brakes do not work when the engine is running?
I would check the power brake booster
What does a brake booster do?
a brake booster supplies power to the brake system. this takes the hard out of the brake pedal allowing brakes to work harder with less effort or pressure on pedal from the driver
Why does your brake pedal go stiff and not work in a morning?
Probably have a defective power brake booster or the vacuum supply to the booster is restricted or leaking.
How does the brake vacuum system work on a 1963 Chevy Impala If I push on the brake pedal I hear a hissing sound inside and the car stalls out?
If you have a power brake booster then there will be a vaccum line that runs to the brake booster on the firewall from the carburator. Check the booster for holes and broken fittings or buy a new booster. if no brake booster then brakes shouldn't affect vaccum
You have changed your brake booster on your 95 Chevy truck and now your brakes wont work nor will it go into gear whats wrong?
It sounds like a vacuum problem. Either you got a bad brake booster or the vacuum line came loose somewhere or cracked when you changed the booster.
Do brakes work when an engine stalls?
Yes they would still work, but it would be much harder to stop the vehicle because you don't have the booster powering the master cylinder, so you would have to push much harder on the brake pedal to stop.
Why does your brakes work with light pressure and not with hard?
You probably have air in the lines or the brake booster is losing vacuum. Have the brakes bleed and have someone put a vacuum gauge on the booster,
1999 DODGE Intrepid 2.7 where is the brake booster located at?
the brake booster is located between the master cylinder and the brake pedal. Inside the fire wall. I found it for $85 but i don,t know how to replace it without ripping out the dash. Found a shop that will do the work for $250.
Why would the brake lights on a 1998 318ti work normally without the headlights but stay on constantly with the headlights?

I replaced the master cylinder and bled the lines on a 1991 s10 Blazer but still no brakes. What else could be the problem?
It could be a few things ...i would check the brake booster.. If it is bad it will make your pedal go all the way to the floor before it will have any brake pedal at all..also i would check your vacuum for the booster for your brakes to work you have to have vacuum on it for it to work !hope this helps, and as allways if you are not sure get a second opinion !
Does a brake booster have to be adjusted if it isn't what will happen?
No adjustment should be necessary on your brake booster. These are a work or fail item except for a check valve in the hose on some models. The brake master cylinder that usually mounts to the front on some vehicles may need to be bled but that is pretty rare these days.
