Brake Warning / High Pedal Effort

Diagnosis & fix steps

LOGIC: Service Brake Hydraulic Accumulator Charge Valve Mechanical Failure. ACTION: Check cut-in (approx. 1,500 PSI) and cut-out pressures with a mechanical test gauge. Inspect charge valve spool for metal slivers; check nitrogen pre-charge in both brake accumulator bottles.

Red Seal field insights

Hauler Interlock: Brake ECM cycles the charge spool based on pressure transducer thresholds; physical contamination locks the spool, starving the oil-cooled disc brake pack.
