Warning: Hydraulic brake fluid can cause eye and paint damage, so care must be taken when handling and storing it. Do not use fluid that has been open for a long time, as it is very hygroscopic. Excessive moisture in the fluid can cause dangerous loss of brake performance.
1. The procedure is similar to the procedure for bleeding the brake system, as described in Chapter 9. The old brake fluid should first be pumped out of the reservoir using a rubber bulb. The old fluid will come out of the system during bleeding.
2. Proceed as described in chapter 9, unscrew the first nipple according to the sequence of bleeding the brakes and bleed the brake pedal until the brake fluid reservoir on the master brake cylinder is almost completely dry, but still so that air does not get into the system.
3. Add fresh fluid to the maximum mark and continue bleeding the system until only fresh fluid remains in the tank and it starts coming out of the nipple. Screw the nipple back on and add fresh fluid to the tank to the maximum.
4. Repeat the procedure for the remaining fittings in the bleeding sequence. Be careful - do not allow the fluid level to fall below the minimum mark in the tank during the entire procedure, otherwise air will enter the system and the procedure will be extended
5. When the operation is complete, make sure all fittings are tightened 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 driving on the road, check the operation of the braking system.
