• Draw off brake fluid until it emerges clear and free from air bubbles. • Tighten the bleed screw. • Installation is the reverse of the removal proce- dure: pay particular attention to the following. • Before reassembling, carefully wipe the rim of the reservoir, the rubber gaiter and the cover to remove all traces of brake fluid. • Top up the brake fluid until the level reaches the “MAX” mark. 2 1 L Note: [ABS] Place rubber diaphragm and reservoir cap in position.

If the vehicle is equipped with ABS , the brake sys- tem has to be bled using the BMW MoDiTeC, and the Control Units, Toolbox ABS, routine; this proce- dure is supplementary to that described in the Re- pair Manual. If the BMW MoDiTeC is not used there is a danger of residual air remaining in the control circuits of the ABS system. • [ABS] Bleed the brakes using the BMW MoDiTeC. 3 Brake fluid ...................................................DOT 4 X Tightening torque: Bleed screw ................................................... 7 Nm Brake caliper to swinging arm ...................... 21 Nm K14000520 • Tilt the brake caliper forward. • Tighten front securing screw (3).
• Connect the brake bleeding device to the bleed screw on the brake caliper. • Open the bleed screw by half a turn. e Attention: Brake fluid level must not drop below the MIN mark during the bleeding process, otherwise air will be drawn into the brake system. Bleed the system again if this happens. 00.51
