2006 Ford Crown Victoria's brake pedal is dropping. I have replaced the master cylinder, booster, bled the brakes twice. Recently I also replaced the brake light switch and the pedal came back up.
The brake fluid level is up and I flushed the system.
What is the problem and what can be done?
Hi Im David, thanks for visiting the site.
So one day you get in your vehicle and the brake pedal goes to the floor or how did this come about?
Did you bench bleed the master before installing?
No, I did not.
This is an unusual and intermittent problem. Repairs are done, there is an improvement and then it returns
Did you manually bleed the brakes?
With or without the engine running?
it takes a lot more than 2 times bleeding the brakes to get it done correctly. Sometimes it can take 5,6 or 6 times.
Bleed them again with the engine running.
