Re: Hello i have a big problem of brakes for a silverado...
Check the brake fluid level in the master cylinder. If it's low or empty refill it and check for a leak. If the master cylinder is full of fluid the cylinder itself could be bad.

If the pedal goes all the way to the floor you have air in your lines somewhere. If the pedal is soft and spongy then there is air in the lines. Start checking around the inside of your tires, and up near your Brake Booster and Master Cylinder
it could be a brake booster problem or a master cylinder problem. If the rear brakes are shoe brakes try to adjust them. If not then you'll have to determine if it's a bad booster or master. Did you some how get air into the hydrolic system
why did you change the calibers,hoses,wheel cylinders,they have nothing to do with the abs pump kicking on.Did you have a pedal before you changed all those parts?
