  1. Run the engine at idle.
  2. Position the transaxle in NEUTRAL.
  3. Depress the brake pedal and hold a constant foot pressure.
  4. If the pedal gradually falls away with the constant pressure, the hydraulic system may be leaking. Perform the following visual inspection in order to confirm any suspected leaks:
    5. • Inspect the master cylinder fluid levels. Normal lining wear may cause a slight drop in the reservoir fluid level. An abnormally low reservoir fluid level, causing illumination of the BRAKE warning lamp, may indicate a leak in the system. The hydraulic system may be leaking either internally or externally. Refer to Master Cylinder Diagnosis .
    • Inspect for leaks at the brake pipe and brake hose connections. If leakage exists, verify the torque of the fasteners and/or replace the pipe or hose.
    • Inspect the connecting brake components for damage. Rebuild or replace the connecting brake components as necessary.
    • Inspect the caliper for leakage. If leakage is evident, rebuild or replace the components as necessary. Refer to Front Brake Caliper Overhaul or Rear Brake Caliper Overhaul .
