So I have the infamous ABS and Brake light issue. It's on a 2001 Silverado 1500HD. Thing is it's got a few other issues and I'm curious if they are related. I have no leaks but I can actually push the pedal all the way to the floor with a little harder pressure than normal. When I do I get a mechanical hum/buzz. Other thing is this truck is 100% undrivable in the rain. The slightest tap of the brakes and the truck darts off to the right or goes to sliding. Where do I start diagnosis though?
