Functional Test

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2001 Honda Prelude, 2001 Honda Odyssey, 2001 Honda Insight, 2001 Honda Civic, and 2001 Honda CR-V. However, it is still accessible from the selected car via links, so may be relevant.
  1. Start engine. Turn ignition off. Depress brake pedal several times. Depress pedal firmly and hold pressure for 15 seconds. If pedal sinks, master cylinder, brakeline or wheel cylinder is faulty.
  2. With pedal depressed, start engine. If pedal sinks slightly, vacuum unit is working properly. If pedal height does not vary, booster or check valve is faulty.
  3. With engine running, depress brake pedal lightly. Apply just enough pressure to hold back automatic transmission creep. If brake pedal sinks more than .40" (10 mm) for all models except Civic, or 1" (25 mm) for Civic in 3 minutes, master cylinder is faulty. Slight change in pedal height when A/C compressor cycles on and off is normal.
