Note: Handle the brake system with care and avoid inhaling dust generated by wear of its components, as it may contain asbestos, which is harmful to health.
Inspection
1. Although 2.0L models are equipped with rear disc brakes, the handbrake operates independently of the brake pedal, using shoes mounted behind the disc that work in the same way as drum brake shoes.
2. To inspect the handbrake pads on models with a single overhead camshaft (SOHC), remove the hub / disc as described in Section 10.
3. To inspect the handbrake pads on models with two overhead camshafts (DOHC), remove the brake disc as described in Chapter 10.
4. Remove the hub/disc or disc (depending on the model), make sure that the brake linings are not worn more than specified in Specifications limit.
5. If any of the shoes is worn beyond the Specification limit, replace all four handbrake shoes as a matched set.
