Brakes have no stopping power

[Grit dog]

Thanks for the help HotRodPC. Going to order a new booster on Monday and get this fixed. I have to go down a really steep hill every day and I really feel alot better with power brakes.

But you said the pedal went to the floor. Completely different issue.
No power assist = hard pedal and booster issue, truck will stop fine with "manual brakes."
Pedal to floor and no stopping power is air in system or a leak.
