I have a (!)(P) BRAKE warning light on my dash. The guy I bought it from said that the truck sat for "a while". He replaced one of the slave cylinders in the rear brakes because it was leaking. The pedal doesn't feel too spongy. I've bled the brakes but that didn't help the light. I did find out that when I unplug the brake pressure warning switch on the aide of the ABS unit, the light goes out. I grabbed some from my local Pull a Part. Will I have to bleed the ABS unit if I replace the switch? I assume so since the switch has a rubber o-ring.

Thanks
