e Attention: The brake fluid must always be visible in the contain- er, because the piston in the base of the wheel-cir- cuit reservoir must always be covered by the fluid. The procedure must be repeated if the fluid drops below the “min” level. 34 1 581 • Very gently pull the handbrake lever until the pump just starts up. • Open the bleed screw, while topping up the container with new brake fluid if necessary. • Pump out the brake fluid with virtually no pres- sure to begin with, then vary the brake pressure. R22000340 • Screw container, BMW No. 34 1 581 , onto front wheel circuit reservoir. • Slowly fill container, BMW No. 34 1 581 , with new brake fluid until it is approximately 1/2 full.
• Connect the brake bleeding device to the bleed screw of the left brake caliper, but do not switch on the device. L Note: If necessary, use a cable tie to secure the bleed hose to the bleed screw. L Note: The higher the brake pressure the faster the fluid is pumped through the system, which means that the level in the wheel-circuit reservoir drops all the more rapidly. • Pump off brake fluid until it emerges clear and free from air bubbles. • Close the bleed screw. • Release the brake. • Disconnect the brake bleeding device from the bleed screw. • Connect the brake bleeding device to the bleed screw of the right brake caliper, but do not switch on the device. • Switch on the ignition.
L Note: After switching on the ignition, always wait for the BMW Integral ABS to complete its self-diagnosis. Do not operate the brake lever until self-diagnosis has completed. L Note: If necessary, use a cable tie to secure the bleed hose to the bleed screw. • The procedure for changing the brake fluid in the right brake caliper is the same as that for the left caliper. • When the brake fluid is clear and free of bubbles, continue pumping until the fluid in the container just disappears from view. • Close the bleed screw. • Release the brake and switch off the ignition. • Disconnect the brake bleeding device from the bleed screw. • Disconnect the container from the wheel-circuit reservoir.
MAX e Attention: After changing and/or bleeding the brakes, always top up the fluid in the wheel-circuit reservoir to the correct level in accordance with the instructions. MIN R28340090 00.41
