Title: Brake light stick on
Post by: Tikvah on August 04, 2017, 04:05:42 PM
I have a dash indicator for my brake lights.  I've noticed occasionally my brake light stays on.  I can punch the pedal and it releases the light.  Where do I look for a problem?
I don't think the brake is sticking... at least I can't feel one.

Could be a dirty brake switch. Could be a maladjusted brake switch. Could even be dirt between the switch and the pedal.

Going further... are your brakes leaking air? On the work bus, after releasing the parking brake, keeping my foot on the foot brake, I let the foot brake up and air continues to hiss until I stamp on the brake again. My codriver last year left it a few seconds late and was alerted to the problem by the LAB.

Could this be related to the tag tire wear issue?

Air brake system on this coach.

Either you have air pressure in there, or the pressure switch is sticking.

Both need an intervention

happy coaching!

MCI's often control that light with a relay.  My dash light stopped working after I installed LED brake lights, they didn't draw enough current to make the relay switch.  My brake lights work fine so the switch wasn't affected.
