My brake pedal travels at least half way to the floor before I get good brake engagement. Brakes are good and stop the truck and my boat trailer just fine. This has developed over time - the pedal was always firm and engaged nicely.
New brake booster within the last two years, no leaks from wheel cylnders or master cylnder. Pads, shoes, rotors all relatively new. No buldging brake lines. No fading away of the pedal when holding the truck in place at a light or some such. Mechanics cant find an obvious problem....
Thoughts?
