Brake and ABS Lights on
 

95 1/2 ton 2WD Silverado with the 350. I had a wheel cylinder leaking and replaced it. The ABS light has always been on (I just bought the truck a few minths ago) but the brake light was never on unril I replaced the Wheel cylinder.

The pedal feels about the sane as my 94 GMC Sierra 1/2 ton 2WD. The odd thing is, if I press the brake pedal hard and hold it, the brake light will go out and stay out until I hit the brake pedal again. I had some electrical gremlins with this truck already. I'm not leaking any fluid, and I checked the E brake switch. Where do I start? Thanks
