Applies To:

Brake Pedal Feels Hard in the Mornings or in Cold Weather
SYMPTOM
The brake pedal can feel hard during the first couple of brake applications, usually in the morning when the ambient temperature is cold.
PROBABLE CAUSE
At cold start, in high altitude, combined with the fast idle retard operation, the intake manifold vacuum supply is at its lowest, resulting in low booster
assist.
CORRECTIVE ACTION
Replace the brake booster and the master cylinder rod seal, and update the PGM-FI software using the HDS.
