In the back should be tail lights which always come on when the headlights or parking lights are on, and stoplights which come on whenever the brakes are pressed. The stoplights should be brighter than the tail lights, but they should be separate.
Hey Brad No, They should be ok. GoodluckJOe
Assuming we are talking about "S" cam air brakes on a truck, check the angle at the end of the slack adjuster to the actuator rod coming out of the air brake can when brakes are applied, it should be 90 degrees, if the slack adjuster is manual adjust it with the brakes not applied and then test again. If they are automatic slack adjusters and you do not have 90 degrees with brakes applied it is worn out or not installed correctly.
No. The one in the middle is a brake light, and should only come on when you put on the brakes.
check the fuse then the bulbs then the brake switch
Does it actually engage the brakes, or just the brake lights? There should be no possible way for the steering wheel to actuate the braking system, but a short in the wiring somewhere in the steering column could be causing both rear signal lights or brake lights to come on.
They certainly should do. If not, the vehicle should not be driven until they function correctly.
You should remain stopped until the bus's red lights are no longer flashing.
When the brake pads are worn the rivets will actually touch the brake rotor when the brakes are applied. The brakes should be changed immediately.
The rear brakes will lock when there isn't enough weight in the rear of the vehicle, the surface is loose (like a gravel road), or they [the brakes] are applied to heavily. Newer vehicles with anti-lock brake systems (ABS) should not have this problem.
Stand on, but remain alert.
If you have a trailer wiring harness it probably has a short in it and is back feeding the circuit when the brakes are applied remove and replace the trailer harness and this should fix the problem.
Depends on the kind of pads/rotors you got. It's normal for some compounds to squeak .
