The procedure for replacing brake fluid is similar to the procedure for bleeding the brakes, except that the brake fluid reservoir must be emptied of old brake fluid.
Execution order
1. Open the first bleed screw and pump the brake pedal until the old brake fluid comes out of the master cylinder.
2. Add brake fluid to the MAX mark in the reservoir and bleed again until new brake fluid appears in the bleed nipple, then screw in the bleed nipple.
3. Bleed the brake circuits of the remaining wheels in the same manner (see figure Location of the brake caliper bleeder screw and figure Using a wrench to loosen the bleeder screw).
4. When bleeding, do not allow the brake fluid level in the reservoir to drop below the MIN mark. Otherwise, air may enter the hydraulic brake system.
5. Check that the bleeder nipples are tightly tightened, install dust caps on them and wipe off any traces of brake fluid.
6. Check the operation of the braking system while driving the vehicle at low speed.
