Question about 1995 Chevrolet K2500
Anytime I drive over 30mph my brake warning light will come on. The fluid, pads, and shoes are good. Could this be a speed sensor issue? This truck does not have ABS.
ABS light comes on with ignition then should go off when you start the car.
If abs sensor does not turn off after disconnecting the battery, then there is a real problem, a faulty sensor or ABS malfunctioning.
When the ABS led comes on immediately after you start the car and stays on usually is one of the relays.
The main one is called surge arrester relay, if it is faulty usually there have been an overvoltage.
There should be two more, usually located behind the black plastic cover of the ABS.
Testing and changing the faulty relay can fix the problem.
If light turns off on startup, and comes back on when you reach some speed, usually you need to check the wheel sensors. You test them unplugging the sensor located behind the wheel and testing it for continuity with a multimeter.
Use Haynes manual to find locations and specs of relays.
Contact a qualified mechanic if you cannot fix it yourself, problems with ABS may compromise safety of the vehicle.

Try this, Since you are applying the hand brake. Manually pull up on the emergency pedal and see if the light goes out. If this does work then you could have one of several problems. but, I am thinking that you might be able to adjust the brake tensioner if this car has one.
