Bench Testing: Rotor

WARNING: This page is about a different car, the 2000 Subaru Outback and 2000 Subaru Legacy. However, it is still accessible from the selected car via links, so may be relevant.
  1. Measure slip ring outer wear. If worn greater than .04" (1.0 mm), replace rotor. Standard diameter is 1.063" (27 mm). Wear limit is 1.024" (26 mm). Inspect slip rings for contamination or roughness. Polish with No. 500 or 600 emery paper or crocus cloth.
  2. Check continuity between rotor slip rings. If continuity does not exist, replace rotor. Connect ohmmeter between each slip ring and rotor. If continuity exists, replace rotor assembly. Check rotor bearing for noise and ease of rotation when turning. Replace as necessary.
