Brake trouble
1997 f150
Here's what I've got:
New rotors
new pads in front & back
replaced barrels in rear
replaced both calipers
Problem:
Brakes go all the way to the floor
The lines have been bled and flushed. The pedal still goes to the floor.
What now? tia

if a booster goes bad you will have NO power assist...master cylinder you probably have a bad seal and it is allowing pressure to leak out the back side...if your brake booster is damp then its the master for sure...never a bad idea to replace the master when they get old and higher in mileage

Thank you for clarifying for me.

The brakes are a sealed hydralic system. If the master cylinder has an internal leak, the system is no longer sealed, letting the pedal go down. The purpose of the brake booster is to decrease the amount of force need to to apply the brakes. If it goes bad, the pedal is harder to push (like when the engine is off). but a bad brake booster won't let the pedal go to the floor.
