Warning! Brake fluid can cause eye injury and damage paintwork. Therefore, be very careful when handling it. Do not use brake fluid from a container that has been opened for more than a year or has been left open for a long time. Brake fluid absorbs moisture from the air. Excess moisture can lead to a dangerous drop in braking efficiency.
1. Brake fluid should be drained and replaced at the prescribed intervals. Since brake fluid may drip or splash when added, place sufficient rags around the master cylinder to protect all adjacent painted surfaces.
2. Before starting work, purchase the prescribed brake fluid (refer to the section "Recommended lubricants and operating fluids" at the beginning of this chapter).
3. Remove the cover from the brake fluid reservoir.
4. Using a hand suction pump or similar device, pump the fluid out of the brake fluid reservoir.
5. Pour new fluid into the tank up to the base of the filler neck.
6. Remove as described in chapter 9, air from the brakes of all four wheels, ensuring that new and uncontaminated fluid comes out of the air bleed screw. Maintain the fluid level in the reservoir while performing the air bleeding procedure. If the master cylinder runs "dry", air will enter the system.
7. Fill the master cylinder with fluid and check the brake operation. The pedal should feel firm when pressed, without any dips.
Warning! Do not operate the vehicle if you are in doubt about the efficiency of the braking system.
