Your power brake booster is probably bad.
Above the brake pedal. If your main brake lights dont work but your third center brake light does, then the brake light switch is not the problem. Its is the turn signal switch.
It may be the turn signal switch located under the horn in the steering wheel. Try holding up the turn signal lever with your left hand and apply the brake. See if that helps.
If you have the same bulb for brake and signal, brake light power needs to be interrupted by the signal lights, The brake circuit has to go through the signal light switch so the problem could be there.
your breaks will not work with out it. break fluid is part of the Hydraulic system It runs to the brake lines and into the calipers Where it pushes on pistons that apply pressure to the break rotor making the car stop.
I don't know about Silverado trucks but all of the emergency (parking) brakes I'm familiar with use the brake cable to "pull" and hold the brake against the drum (or disk), so if the cable breaks you simply cannot apply the emergency brake. That is, it is automatically released if the the cable breaks.
what do you have to do to change the center brake light
The turn signal switch is mounted inside the steering column and you control it with the turn signal lever. The turn signal Flasher Relay is located: Behind center of instrument panel .....by the way, the gas pedal is on the right, and the brake is on the left
The center brake light replacement will require replacing the entire brake light assembly. Remove the wiring harness. Remove the center brake light retaining screws. Reverse the process to install the new center brake light.
Have your foot above, but not on the brake. Allows you to quickly apply brake.
If only the right rear brake/signal light is effected it is not the fuse. Inspect the right rear brake/signal bulb, socket and wiring.
In many cases, the brake light and the turn signal use the same bulb.
Could be the wear indicators on the brake pads Last time pads were replaced?
Brake pads are probably worn out. Have a trusted mechanic inspect the brakes soon!
You probably have a turn signal bulb with two filaments one for the turn signal and one for the brake light. If the ground connection is bad on the turn signal circuit then the current would need to find another path to ground. The only other one available is through the brake light filament to the ground on the center brake light. Try removing the taillight assemblies from the vehicle look for what is probably a black wire screwed to the body or a circuit connection and either tighten the screws a bit or clean the connections.
the turn signal switch is probably bad
it means that you have to check your breaks
Which brake lamp are you needing to change? Brake/turn signal lamp.
Semi-trucks are equiped with two brake lines. One in the normal air brake line and the other is the emergency air brake line. If your normal breaks fail, the emergency break will automatically switch on so you will be safe until you can stop. That is how you will tell your breaks fail-your emergency break will initiate.
Since most brake/turn use the same filament in the bulb(1157) then if the turn signal switch is bad or offset then it will effect the brake lights.
Time to add dome brake fluid.
short circuits in the turn signal and brake light circuits
i have conected the black and red wire to the brake and it works (the brake light that is) and i conected the blue and white to the signal lights each wire being left and right signal and it all works. but when i brake all of the light lights up the red bar for the brake and the orage bars left and right when i signal left or right whiles braking the signal works but the other signal light sticks on with the brake light. so if any one as any idears please let me know thanks
One of two things. Either the brake light switch behind the brake pedal. Or try wiggling or rotating your turn signal stalk in a circle motion. If the brake lights work when the turn signal stalk is wiggled then you need to replace the turn signal stalk.
