The problem you are describing sounds like the master cylinder. Usually the brake pedal is hard when the vacuum booster goes bad. It would feel the same whether the engine is running or not since there would be a vacuum problem and vacuum is provided by the engine. When the pedal is fading it's usually a problem with a seal inside of the master cylinder. When you replace it, save yourself some time and bench bleed it. Fill it with fluid, and if equipped, which rebuilt ones usually are, screw in the plastic fitting lines and run the open ends back into the reservoir and pump the actuator until the bubbles stop. Bolt it to the vehicle and start the lines. Have someone press the pedal, and while all the way down hold it there. Snug the lines up and have them release the pedal. Have them press it to the floor again and hold it there. Loosen the lines slowly to let what little air remains out, tighten them, and then have them release the pedal. That will rhymes with duck but starts with "s" (avoiding censorship) the remaining air out the top instead of bleeding the entire system from the wheels and pushing the air all the way through them. Please rate my assistance and leave a testimonial.

How do you know that a brake booster is bad?


Booster problems are rare but they do go bad sometimes.
A bad booster generally causes the brake pedal to feel hard to push down, and a lot of pressure on the brake pedal is required to make the car stop.
Rarely, a vacuum brake booster will develop a vacuum leak, which can cause engine performance problems, hissing or whistling noise, as well as requiring increased pressure on the brake pedal to stop.

The first test:
With the vehicle parked, turned OFF, and the parking brake set, pump the brake pedal 5 to 6 times. If the pedal gets harder to push after several times, your booster is probably good.

The second test (To make sure):
After the test above, without making any changes, press and hold the brake pedal with light to moderate pressure.
Now with your foot still on the brake pedal, start the vehicle.
If the booster is good, you will feel the pedal go down when the engine starts.

Hope this helps!

Brake pedal drops very low on first press only


It is most likely you have air in the brake fluid. The first press of the pedal compresses the air and the effect lasts for a little while.
Another cause may be warped (bent) rotors, the pads can be pushed back into the calipers by the off center area of the rotor. This means that the pads have to travel further in order to contact the rotors when you press the pedal.

Vw golf 2000 the brake pedal is to soft when you apply it and seems like is not going to stop but it does, what is the problem?


Not sure if you have done all this.



BRAKE BOOSTER INSPECTION

Functional test:
1. With the engine stopped, Depress the brake pedal several times, then depress the pedal hard and hold that pressure for 15 seconds. If the pedal sinks, the master cylinder, brake line or a brake 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 the check valve is faulty

Leak Test:
1. Depress the brake pedal with the engine running then stop the engine. If the pedal height does not vary while depressed for 30 seconds, the vacuum booster is OK. If the pedal rises, the booster is faulty
2. With the engine stopped, depress the brake pedal several times using normal pressure. When the pedal is first depressed, it should be low. On consecutive applications, the pedal height should gradually rise. If the pedal position does not vary, check the booster check valve.

Check valve test:
1. Disconnect the brake booster vacuum hose at the booster.
2. Start the engine and let it idle. There should be a vacuum available. If no vacuum is available, the check valve is not working correctly. Replace the check valve and retest.

Need to know which fuse is for the brake lights all three stopped working at once


It's probably not a fuse -- check the brake light switch that's attached to the brake pedal shaft. Pressing the pedal compresses the plunger, making contact and turning on the brake lights. Manually press and release the plunger several times and see if the light function is restored. If that doesn't work, try a little (VERY little) WD-40 or silicone lube on the plunger. If neither works, you'll need to replace the switch - an easy and inexpensive job.

My break light swithes on sometimes without me even pressing the breaks. The break light also sometimes stays on even when I have taken my feet off the break. I have tried changed the break light switch...


Did you adjust the brake light switch correctly? To adjust the brake light switch, first press the brake pedal down a few inches, then pull the switch plunger rod out of the switch toward the brake pedal arm, as far as you can without using excessive force. Next, return the brake pedal to the pedal stop position against the pedal stop and pull the brake pedal toward the rear to push the brake light switch actuating plunger rod into the switch housing limited by the travel of the brake pedal arm rear travel stop position. This procedure automatically adjusts the brake light switch correctly.
If the brake lights still don't turn off with the brake pedal released, check the brake pedal arm for sticking or binding that is preventing the brake pedal arm from returning fully to the pedal stop when the brake is released.

New master cylinder and booster. Brakes stop good


Well if you have bled it correctly starting at the farthest out(PS Side Rear) and working to the closest(DR Side Front) and you make sure to close the bleeder valve before letting up and repumping the peddel,then I would say that the seals in your new master cylinder may be bad.When you bled the second or third time if there was no air then I would say you have a bad master cylinder.If there was air then you have another problem.Well hope this helps and good luck.

2004 chevy venture will not shift from park. The engine is running and the brake pedal is pressed.


The blocking bracket might be jammed. Stop the engine, nudge the car a little and try again to move the lever without pressing the brake pedal. 
If this works move the lever several times to loosen the bracket, leave it in neutral, press the brake pedal  and start the engine. Leave it running at idle for a while , till the oil heats up - 5-10 minutes , depending how cold is outside. Then repeat the lever movement till the efort becomes neglijable. If it doesn't or jams again take the car to the repair shop, it needs tinkering.

Have to press hard on breaks to break on 528i bmw 2000


sounds like brake booster not working
check vacuum hose that goes to booster is ok and not leaking
engine off
pump up brake pedal several times
hold brake pedal down
start engine
pedal should sink down approx half to 3/4 way down indicating booster is working
if pedal doesnt go down when engine is running booster has leak or no vacuum supply from engine which requires great pedal effort to try and get vehicle to stop.
