    CAUTION
    A magnetic field from a pick-up tool or magnetic parts tray could permanently damage the magnetic pattern on the hub/bearing tone ring.

Installation

Installation procedure is the reverse of removal, except for the following:
  • Clean the mating faces of the hub and disc.
  • Use the magnetic field viewing card to ensure that the magnetic field on the tone ring is not damaged.
  • After connecting the electric parking brake caliper harness, wrap the connector seam with electrical tape to prevent dirt ingress.
  • Pump the brake pedal at least 5 times to seat the pads against the brake rotors.

    Warning
    Always check that the brake pads are seated correctly before driving the vehicle.
  • Refer to the Alignment Requirement tables to determine whether an EPAS alignment check (EC) or four wheel alignment check (AC) is necessary. If performed, add the alignment check/adjust as a separate activity. See Alignment Requirement - Suspension.
