Did you bleed the brakes with the engine off? -Jim

Yes, bled it with the engine off and had good pedal but when I started the truck my pedal instantly goes completely to the floor.

Assuming you blead the master cylinder off the truck first, then blead out the brake system (right rear, left rear, right front then lastly left front) I'd say you got unlucky and have a defective master cylinder. I work at NAPA and, unfortunately, it sometimes happens. HTH. - Jim


Im going on my third Master Cylinder. Autozone sells crap parts and I will not buy from them anymore. Im buying an AcDelco Master Cylinder ( That happens to be the same price as the cheap Fenco from Autozone) So under warranty im going to exchange them. Im doing this on a 98 chevy c1500 so I feel your pain. Ive had to change almost the entire brake system and im only at 148,000.

Brake booster, ABS SYSTEM!, brake lines (most of them) Two master Cylinders (Thus far), bled it several times. I still have a squishy petal but it stops. Next is rotors, and wheels bearings. Also I've changed both Calipers and wheels cylinder and turned the drums and changed shoes.
