How to disconnect the wire from the pressure differential switch on Chevrolet Astro?

Turn off ignition and locate the pressure differential switch. Disconnect its wire and ground it using a jumper wire. With ignition on, check if the instrument panel warning light illuminates. If not, replace the bulb or fix the circuit. Reconnect the wire and ensure master cylinder reservoirs are full. With a bleeder hose on the rear wheel valve, have a helper press the brake pedal while you open the valve; the warning light should turn on. Repeat for the front brake. If the light doesn't turn on but works with a jumper, replace the brake proportioning valve. To do so, protect painted surfaces, disconnect hydraulic lines, and the electrical connector. Remove the bolt and valve. Install in reverse order and bleed brakes.
