1. When working with brake system components, be aware of asbestos dust generated by wear on brake linings. Do not inhale dust - it is harmful to health.
2. Remove the cap from the auxiliary brake fluid reservoir, pump out approximately 60 ml of fluid into a sealed container and discard it.
3. Loosen the front wheel bolts, jack up and support the front of the vehicle on axle stands. Remove the front wheels.
