IS it the BRAKE LIGHT or the Parking Brake Light? If it is the BRAKE LIGHT, then your pedal must be going down far enough to hit a sensor that sets off the brake light to tell you your brakes need serviced. Normally this means you are low on brake fluid. If you are low on brake fluid FIND OUT WHY! You may have excessive brake pad wear, or a leaking brake cylinder, or your master cylinder may be going out. If you keep pumping the brakes and then stand on it hard, feel for the pedal to eventually go soft, if it does, then normally the seals in the master cylinder are going out. If you pump the brakes and the pedal never gets hard, then you have a serious brake fluid leak. If the Parkign Brake light stays on, then your parking brake is not fully releasing, at least where the contacts are to remind you it is on. This can be adjusted.
Start the car, place you foot on the brake and push and hold it. If the brake pedal very slowly sinks toward the floor, the master cylinder is bad. Of course a leak at the master cylinder means it is bad. Don't ignore any of these 2 symptoms as it can stop working at any moment, and leave you with no brakes. When looking at the master cylinder look at the wall or booster that the master is bolted to. If u see sweating, or paint pielling at the mating the master is leaking from the seals.
Excessive heat, typically generated by excessive braking, incorrectly adjusted components, or improperly fitted components, or, in the case of air brake systems, faulty quick release or relay valves, brake chambers, or slack adjusters.
Best ways are if you can see exposed cable underneath the truck, go underneath and yank down on the cable as hard as you can. If the parking brake isn't needed or you just need to free the brake to move the truck and can go get it repaired if necessary, cut the cable back by the brake and the brake will release. Shouldnt cost more that 150 bucks to get a new e-brake installed.
The master cylinder on a 1999 suburban is pretty easy to change. Under the dash, disconnect the clutch pedal from the cylinder rod. disconnect the brake lines from the master cylinder and allow to drain into a container. Unbolt the cylinder and remove. Install the new cylinder and connect the lines and rod back up. Add new fluid, and bleed the slave cylinder to finish the installation.
put new disks and pads in my 2005 V beetle bleed them and brake pedal still not to the top go down about 2inchs how do i get a nice hard pedal
Power brake booster failure or vacuum supply to booster insufficient.
Hardness in the brake pedal can because by low brake fluid. Air in the brake lines can also cause the pedal to push hard.
try bleeding the brakes or checking the fluid
The brake pedal vibrates.
Probably the brake booster going bad.
A hard brake pedal can be caused by several different factors. It can be as simple as the brake pedal getting caught on something to the power brake booster being bad. You could also have a brake pad or shoe that is sticking, causing the brake fluid to boil. When brake fluid boils, it expands and can cause the hard brake pedal that you feel. A brake pedal that is hard to press can also be caused by a build-up of water in the brake line. The water in the brake line lowers the boiling point of the brake fluid. A hard brake pedal can also be the result of a restriction in the brake line, such as a bent brake line or foreign material in the brake fluid. The most common cause of a hard brake pedal is the sticking brake pad or shoe, causing the brake fluid to boil. Tracking down what is causing the hard brake pedal can be frustrating, to say the least. Take the vehicle for a drive and when you come back, feel your brake lines near the wheels. Caution: The line may be very hot! If one is extremely hot, you may have just found the culprit causing the hard brake pedal.
brake switch located on the top of the brake pedal
you will have a hard brake pedal
hard brake pedal is the most obvious sign only way i know to test a booster, is to turn engine off. use brakes several times till pedal is hard. then with brake applied,start engine. the brake pedal should then soften.if the pedal stays hard the booster is bad
The power brake booster is failing.
