The stop light switch (Fig. 22) is an air-signaled electrical switch which is turned on any time a brake application is made. The switch is usually connected to a double check valve and can be plumbed anywhere in the application side of the circuit.
The stop lamp fuse is in the left kick panel inside the vehicle. It is a 15amp fuse that powers the stop light switch on the brake pedal. The brake light switch sends power to rear brake lights. fuses. manual transmissions.
Your brake light switch is a simple spring-loaded switch that is held open by a tab on the brake pedal, keeping the brake lights off. When you push the pedal down, the spring causes the switch to close, completing the electrical circuit and turning on the brake lights.

They apply when air pressure leaves the brake chamber and release when air pressure builds up in the chamber. Spring brakes use a different type of brake chamber from service brakes.
It takes less than an hour, and if you use an after-market replacement motor, you can save almost $200 by doing the job yourself.
For the most part, the brake light switch is built to last just as long as the car does. Generally, these switches will wear out due to the continuous use that they get.
Never replace a blown fuse with one of a higher amperage, which can be dangerous or can cause damage to your electrical panel wiring. … If the fuse blows again, there may be a problem with a particular appliance or you may be overloading the fuse with too many electrical demands.
Due to the way fuses are engineered, the likelihood that a fuse would become faulty without blowing is pretty slim, but there are rare instances in which a fuse might appear completely fine, even though no current runs through it.
One of the most dangerous scenarios involving non-working brake lights is on the highway and while driving at night. Without brake lights, other drivers can not see you very well in the dark, making an accident very likely. You also run the risk of getting pulled over and being fined by a police officer.
Snub braking involves applying the brakes firmly enough to feel a definite slowing down which reduces your speed by 5 mph in about 3 seconds and then releasing the brakes. When you speed rises to your maximum safe speed , repeat the snub braking technique.
The air brake system does this with an electric switch that works by air pressure. The switch turns on the brake lights when you put on the air brakes. Some older vehicles (made before 1975) have a front brake limiting valve and a control in the cab. … However, they actually reduce the stopping power of the vehicle.

A bad brake light switch, for example, can trigger the ABS and traction control lights, but it can also prevent engine start or even transmission shifting. … Also, a bad brake light switch can trigger the ABS lights and traction control lights to stay on.
The cost to replace a circuit breaker switch or fuse is $100 to $200. Standard, 15- to 20-amp switches run $5 to $15 each. Standard, 15- to 20-amp fuses come in packs of three for about $5 to $10. Older circuits and fuses may be difficult to find and cost up to $70.
