Warning: Hydraulic brake fluid can damage eyes and painted surfaces, so care must be taken when handling and storing it. Do not use liquid that has been kept open for a long time as it is very hygroscopic. Excessive moisture content in the fluid contributes to a dangerous loss of brake performance.
1. The procedure is similar to the procedure for bleeding the brake system, as described in Chapter 9. Old brake fluid from the tank must first be pumped out with a rubber bulb. The old fluid will come out of the system when pumping.
2. Proceed as described in chapter 9, unscrew the first fitting according to the brake bleeding sequence and bleed the brake pedal until the brake fluid reservoir on the master brake cylinder is almost completely drained, but flowing so that no air enters the system.
3. Drink fresh fluid up to the maximum mark and continue to pump the system until only fresh fluid remains in the reservoir and it begins to come out of the fitting. Close the fitting and top up the reservoir with fresh fluid to the maximum.
4. Repeat the procedure for the remaining fittings in the bleeding sequence. Be careful - do not allow the liquid level to fall below the minimum mark in the tank during the entire procedure, otherwise air will enter the system and the procedure will stretch
5. When finished, make sure all fittings are tight and all dust caps are in place. Wash off all traces of brake fluid and check the fluid level in the master cylinder reservoir.
6. Before leaving on the road, check the operation of the brake system.
