Brakes acting weird
Hey guys I've been having some brake issues. Lately the had to stand on my Brakes and put it all the way to the floor to get the truck to slow down. There really isn't any pedal resistance as you push it either. And the brake light on my dash came on and I have no idea what that means either. It's my DD so I need it in good shape soon. It's getting unsafe to drive. So any ideas or help on what you think its problem is would be great. Thanks guys.

The brake light comes on when there is an imbalance between the front and rear brake systems. Usually the rear wheel cylinders are leaking (if you have front discs, if you have drums in front they can be suspect too) or the master cylinder is leaking. Once the fluid leaks out the other end of the truck is doing all the braking work, hence the imbalance in braking pressure.

Agreed, the light is on because there's a pressure difference between the front and rear. Either the master cylinder is pushing the fluid through but there's a leak downstream, or the master cylinder is not pushing the fluid through. Check the entire system for leaks, and check for hose expansion. If none are found, replace the master cylinder.
Don't drive it until it's fixed.
