New M/C installed. No leaks, hardware good. Cannot get a good pedal. Truck will stop but the excessive pedal travel is scary. Was told dealer is the only one who can bleed these because dealer can cycle the ABS and remove excess air in module. Another person told me the modulator valve might be bad (dirt on dump valve prevents it from sealing and fluid is going into accumulator vice the lines). Was told this valve is not serviceable. Anyone had this problem and does anyone have any ideas/solution? ABS System is Kelsey-Hayes 4067 AA80340319BAX Thanks.
