When im driving, if the truck is facing usually facing down hill, the brake pedal moves forward and gently applies the brakes.

I thought it could have been a couple of things:
1-air in the brake lines
2-too much fluid in the master cylinder causing an air bubble and causing vacuum problem

I just got done bleeding the front brakes and adjusting the fluid level in the master cylinder. It still will gently apply the brakes....

as far as i can tell its just the front brakes applying because im pretty sure the rear shoes are worn out, any help?

 

does anyone know what this could be from? possibly the whole master cylinder or could there still be air in the brakes lines?

 

Well the brake pedal is a lever. If you dont wanna gradually slow down then just stomp on the pedal.

 

Check that the pedal return spring is good.
May also be a bad booster.
