Replaced my whole brake system on my 73 charger, so why does the dash brake light come on when I apply the brakes. Bled the bejesus out of the master cylinder and system. New powerbooster, master cylinder, proportioning valve, hard lines, flexible lines, calipers, rear cylinders, so [Edited by Moparts - Keep it clean]. Also I might add no leaks. Car stops ok and pedal does not go to floor. Light comes on when the pedal is released and goes out when I give the brake a quick tap. Manual says that when light goes on some part of the system malfunctions. Anyone have any Ideas o how to troubleshoot this headache. Mopar rules!
