As above, I press the pedal and the pedal gets sucked a couple inches toward the floor. Doesn't hit the floor completely.

 

I'm thinking faulty brake booster but never had an issue before so wanted some input

How do the brakes behave with the engine off?

From what I remember pretty solid, been a couple months since it was last used so not 100% sure but can't remember anything odd with it off.

There are valves inside the servo which allows an equal amount of vacuum either side of the diaphragm at rest. If these valves wrong it allows a higher vacuum on the MC side of the diaphragm causing it to move forward. These valves are operated as the pedal is depressed. A new servo should sort this out.

 

Just check the MC seal isnt leaking brake fluid into the servo as this causes problems inside. You will know by your fluid level.

 

Its shocking the amount of servos we replace on modern cars these days.

Yeah Chris

 

Totally agree i had to replace my servo quite awihle back now , with exactly the same sympoms
