OK.... I'm still confused. The brake light on the dash is still on. I unplugged the master cylinder wire, it was still on. I put a jumper wire between the 2 contacts on the plug, and still the light is on. I proceeded to do the same with the proportioning valve, e-brake, and the ABS ( which was a little trickier ) and still the light never shut off. Is there anywhere else on the vehicle that triggers the brake dash light to come on? Brakes are working fine, but I don't want to remove the bulb, & want whoever drives my truck to know to release the e-brake before drivig off. ( I habitually use my e-brake )
