Metro & Tracker

  1. With engine off, depress brake pedal several times to exhaust vacuum from power brake unit. Depress brake pedal and measure brake pedal travel until initial resistance is felt.
  2. Brake pedal free play should be .04-.32" (1.0-8.0 mm). If brake pedal free play is not within specification, check stoplight switch for proper adjustment. See STOPLIGHT SWITCH under ADJUSTMENTS .
  3. If stoplight switch adjustment is okay, check brake pedal push rod and master cylinder pin for looseness. If brake pedal push rod and master cylinder pin are okay, check brake pedal height. See BRAKE PEDAL HEIGHT under ADJUSTMENTS . See Fig 1.
