SOURCE: brake failure/anti lock symbol and parking brake light stays on

The master cylinder has failed, the fluid bypasses from one cylinder to the other, this is really 2 cylinders in one, the brake system is split in an X pattern.

SOURCE: 1991 Maxima cruise control cuts out.

I had a problem with the interlock switch located on the brake pedal. There are too switches one for the brake lights and one dedicated to the cruise control. If either switch is acting up it will affect the cruise control. Then interlock switch is the same switch that is used on the clutch with cars that have a manual transmission. It has smaller electrical terminals in the connector than the brake light switch. You can jumper the connection and see if it solves the problem. You still have the other switch that will disengage the cruise control when you hit the brake. If that is the problem then that's the one you need to replace.

SOURCE: Electrical power system service required.....ABS

usually caused by failed generator. Fix the generator and other lights will also extinguish. The car should jump start, but will not stay running without a charged battery. Recommend removing the generator and take to parts store for testing. Would you like instructions for removing generator?

2005 Hyundai accent gear shift stuck in park after brake failure


Make sure the brake lights are coming on if not the release solenoid that unlocks park gets no power and will not release the shifter from park position. Also check the owner's manual for a possible way to override the solenoid lock.

ABS/Parking Brake?Service Engine Lights are on But Runs Great


Does ABS work properly? Get on dirt road and try to lock brakes (do this carefully insuring no police car tailgating,lol) Could be bad wheel speed sensor. Check codes with scan tool capable of reading ABS and trans codes.

I have a 2006 Chevy Trailblazer, the problem I am having is the brake sensor light will not go off and it keeps beeping. I was low on brake fluid and put some in however the light and beeping will not...


{: ) The brake fluid sensor is very important because it will tell you through the warning indicator if the fluid level is critical, specially while you are driving on road. You can try a few steps just to rule out some possibilities. Better if engine is off, but keep ignition on while proceeding with tests. Transmission in Park position,and the parking brake DISENGAGED fully.

Sometimes its not enough to put some, better complete fill to max level. Check again the sensor light..
If same problem, try to remove the brake fluid sensor connector. Check again.
If the connector has two wires, use a thin jumper wire to connect the two ends. Check again.

If Yes progress, then you need to replace the brake fluid sensor.
If still No progress, return the connector to its place. It's possible the parking brake switch is shorted, or the wires shorted to grouind. The system may need to be checked thoroughly.

Brake pedal is hard but brakes not very effective. booster holds vacuum. replaced booster check valve, no change. dash brake light stays on most of time but sometimes goes out for a while then comes back...


Check the brake fluid first.is it low or no brake fluid at all.is the brake fluid got dried up or leaked out. Sounds like the power brake booster is bad, that is what the master cylinder is bolted too. There is a rubber hose that has a plastic valve in it were it snaps into the booster, Pull that rubber hose out of the booster and off of the engine, Now the end that you took off the engine. You should be able to **** through the line, but not be able to blow through it. If you can then replace the valve, It is a one way valve.
If that is all right then hook hose back up to the engine and start engine, You should hear a major vacuum leak at the valve end, put you finger over the valve and it should stop making noise and engine should smooth out. If it don't the rubber hose must be leaking or the tube on the engine were the hose hooks to is stoped up.
Also check the master cylinder if power booster is replaced. If the brake light is coming and going check the brake light switch. check fig for the internal assembly parts:-- bdea807.gif

To check engine vacuum, connect a vacuum gauge to the supply hose that runs from the intake manifold to the booster. A low reading (below 16 inches) may indicate a hose leak or obstruction, a blockage in the exhaust system (plugged catalytic converter, crushed pipe, bad muffler, etc.), or a problem in the engine itself (manifold vacuum leak, bad valve, head gasket, etc.).
The condition of the diaphragm inside the booster is also important. If cracked, ruptured or leaking, it won't hold vacuum and can't provide much power assist. Leaks in the master cylinder can allow brake fluid to be siphoned into the booster, accelerating the demise of the diaphragm. So if there's brake fluid inside the vacuum hose, it's a good indication the master cylinder is leaking and needs to be rebuilt or replaced. Wetness around the back of the master cylinder would be another clue to this kind of problem.
To check the vacuum booster, pump the brake pedal with the engine off until you've bled off all the vacuum from the unit. Then hold the pedal down and start the engine. You should feel the pedal depress slightly as engine vacuum enters the booster and pulls on the diaphragm. No change? Then check the vacuum hose connection and engine vacuum. If okay, the problem is in the booster and the booster needs to be replaced.
Vacuum boosters also have an external one-way check valve at the hose inlet that closes when the engine is either shut off or stalls. This traps vacuum inside the booster so it can still provide one or two power assisted stops until the engine is restarted. The valve also helps maintain vacuum when intake vacuum is low (when the engine is under load or is running at wide open throttle). You can check the valve by removing it and trying to blow through it from both sides. It should pass air from the rear but not from the front.
Replacing a vacuum booster is a fairly straight forward job. All you have to do is disconnect it from the brake pedal on the inside and unbolt the master cylinder. The pushrod that runs from the booster into the back of the master cylinder must have the specified amount of play.
You will typically find the power brake booster mounted on the firewall attached to the master cylinder. The master cylinder is connected to the brake pedal.
Thanks. keep updated for any more query.you can rate this solution and show your appreciation.

Brake warning lights stay on when i press the foot brake .the brake lights work ok .


You may just need to fill the brake resorvoir with brake fluid, when you are NOT pressing the pedal the fluid in the resovoir is low and the light comes on.

When you DO press the brake pedal you are forcing brake fluid level to go higher and this tells the sensor in the resovoir that the resovoir is full.

My jeep wrangler 1994 manual brake light stays on after a release the handle.


That light usually has two functions: (1) Parking brake is set and (2) hydraulic brakes system failure. I would assume that you have had a failure in the regular brake system, and trouble shoot that. Check fluid level, then make sure all 4 wheels are applying the brakes. Most systems have a split, so you could get a failure of say the front brakes and still have rear, or vice versa, so you might not realize at first that you have a failure, just a longer stopping distance.

Other option is a failure (short) of the switch or wiring harness that is activated by the setting of the parking brake.
