About a month ago my brake pedal was soft until the last 20% of it travel. For that last 20% of travel it braked well and during the first 80% of travel is braked the truck slightly. If I turn the truck on and park it, I can pump the brake a few times and the pedal gets firm after 40% of travel, but then when I drive again, it only really stops the truck for the last 20% of travel.
I found one rear shoe had lost the brake material, resurfaced the drum and but new shoes on both sides. I thought this would explain the problem - because the shoe would expand to contact the drum "taking up most of the travel" and then the other brakes would get pressure and stop the truck. BUT, after the new shoes I still have the same problem.
I have removed the ABS from the equation by unplugging the brake fluid reservoir indicator sensor - as my factory manual told me to do - but that does not help.
Any ideas what would cause this sudden change? The brakes were firm close to the top of travel for a few years and then all a sudden one day they got soft.
