Generally The brake light only indicates the parking brake is on and/or low fluid in level. You are correct that it indicates a vacuum leak recheck ALL vacuum lines you should be able to hear it as well.

SOURCE: brake light is on and chime is on

No the light and chime does not indicate worn out brake pads or shoes.
However, you were correct to add fluid to the correct level.
Just to be clear, you are talking about the red brake indicator light on the dash and is not accompanied by the amber ABS brake light.
If the ABS light is not involved, there is a magnetic switch located in the brake master cylinder. When the fluid level is low, it triggers a switch in the master cylinder and causes the light to come on.
Some times a "gentle" tap on the master cylinder reservoir will loosen the stuck float and turn the light off. One way to verify the switch is causing the issue, you can disconnect the harness connector at the master cylinder and the light should go out.
Start there and let me know.

check to see if all the bleaders are closed on the calipers. make sure all the lines are good also. something could have shacken loose.

SOURCE: add brake fluid light on but fluid not low

Sometimes the float in the master cylinder gets stuck and you have to carefully work it up and down with a screwdriver or something. The switch might be bad on the float too. If the low fluid switch is telling the system that the master cylinder is low, that will cause the "Brake" light on the dash, to come on too.

R1995 chev k1500 dieseleset brake warning light

Usually the warning light involves the low fluid switch on the master cylinder, the switch on the equalizer valve if equipped, and the switch on the parking brake. One of those switches may not be working.

How do I top up my brake fluid on my bmw530d 2006

ok your beemer doest need brake fluid added unless there is a leak in the system. you have brake pad wear indicators that light up dash light when brakes get low. the fluid in system goes down as pads wear fluid does not need added to system. at a glance at master cylinder i can tell if pads need looked at. the master cylinder is under engine cover at fire wall drivers side remove and look but dont add unless a leak is present and then have repaired.

The brake sign is on,on my dashboard ?

Could be this...
Master brake cylinder may be low on fluid. If you have a leak you would also have braking problems. If it is low, it may be due to thin brake pads. The pistons in each brake caliper would be further out, and they take brake fluid out of the master cylinder to do it. So, adding more fluid may turn the light off, however you should have your brake pads inspected. Also, adding more fluid now will make a big mess when the pistons are squeezed back into the calipers to accomodate new brake pads. All that fluid has to go somewhere, and it will run out the top of the master cylinder.

Also, while your checking the fluid level look at the electrical connections on the master cylinder and make sure they are clipped all the way in.

Low brake fluid light comes on when its real cold

A comment from the FixYa Moderation staff:

The brake fluid actually 'contracts', as the ambient temperatures drop. The colder it gets, the more the level is apt to drop, due to this charasteric of brake fluid..

Now, couple this condition with low brake pad thickness, your light will come (the fluid is measured with a sensor in the reservoir) on when it is colder, and go off when the engine compartment warms up; thusly allowing the fluid to expand slightly.

Note that the brake fluid level drops proportionatly to brake pad wear. If you level is low enough to light the light, you are nearing the interval for a brake pad replacement. Adding brake fluid to the master cylinder is NOT advised at this point in time.

If you DO add fluid, and eventually replace the front brake pads, thereafter, the fluid you added will be forced out of the master cylinder, and it will leak all over the paint under the master cylinder. Brake fluid can and will damage painted surfaces.

Best solution we can give you: Simply replace, or have replaced, the front brake pads. The low fluid level condition will rectify itself, as the new pads will force the fluid level in the cylinder reservoir back to its proper level.

Thanks for choosing FixYa

E Brake light is on

based on the very limited amount of information given, in general when the brake light comes on it could be for a variety of reasons but it is always best to start simple. Open the hood and somewhere towards the back you should see a plastic container that houses the brake fluid. It should have a warning on top about using only DOT approved brake fluid or some similar warning. Check the level as indicated on the outside of the brake fluid tank. If it is low add to the proper level. The fluid level will be low because you either have (A) a leak or (B) your brakes are going to need to be changed soon. Adding fluid (should) make the light go off but you should have the brakes inspected ASAP and most places do it for free.

How do i change brake fluid in my 2004 Hundai Accent

1st check the easy things, that would be the brake fluid level. If it's low, the light will go on. Next check the emergency brake, if it's on slightly, the light can come on. Your fluid should be changed when u have a brake job done, the light wouldn't be on for that, only if there is a problem w/ the system. Check this out asap, as it can be unsafe to drive. If adding fluid to the proper level results in the light going out, make sure to check the level daily to make sure u don't have a leak in the system (and u can look under the car for signs of a leak-drips stains puddles). As your brakes wear down, it is normal to have to add fluid, but only a small amount maybe a couple of times between brake jobs. If u have the brakes done in the future, have them flush out the brake system. This is overlooked most of the time, and can result in problems down the road w/ corrosion of calipers and brake cylinders, which lead to premature wear on the brake pads and shoes. Let me know how u make out.
