I cant figure out what is wrong with brakes. Brake pedal has to travel all the way to the floor until it starts to brake.
Then the engine is off you can pump the brakes , but it still feels spongy. then depresing the pedal, in the middle of pedal travel feels small resistance, but it clicks and goes deeper.
Did bleeding - didn't helped.
Had a dealer inspect it - he said it's master cylinder.
I instaled a new Master Cylinder myself, bled the system - same thing, nothing changed at all..
Now I'm quesing it's brake booster. But it's pretty expensive, I don't want to throw any more money replacing good parts.
When I was changing master cylinder, noticed one thing - then I touched the pin coming from power brake booster I heard the air coming out. (That pin supose to push the master cylinder). Could it be, that it's leaking vacuum thru here ?
Inspected vacuum hoses for leaking , but didn't noticed anything.
Could any one explain how to check brake booster if it works
properly?
Could something else be wrong ?
