brake pressure loss and pedal going straight to floor is mostly caused by loss of brake fluid or air in brake system look under car and on inside of wheels to see if fluid is leaking. check brake fluid level at master cylander if no fluid seems to be leaking, have the brake system bled for air. this is the simplest remedy to start with if that doesnt fix it have the brake power booster checked to make sure fluis is not leaking into that also check on firewall in engine bay round booster for fluid and on inside of cab on firewall for fluid
Probably leaking at the rear of the master cylinder and being sucked through the boost and burned as fuel Remove master cylinder and look for traces of fluid at the bottom of booster
in the master cylander fluid resevoir,which is located under the hood on the front of the brake booster, generally on the drivers side
it is usually the rear brake cylinder that's leaking and needs to be replace on that side.
