Brake Bleeding: Service and Repair
Electronic Stability Program (ESP) System
BRAKE BLEEDING AT THE DEALERS (WORKSHOPS)
NOTE: In section 1.1 to 4.3, the bleeding procedure is described without bleed machine. Ensure that always sufficient brake fluid is in the reservoir.
Using a bleed machine simplifies these sections analog to section 5 "Brake fluid renewal". Then the bleeding process should be accompanied by
additional pedal strokes (about 5x per wheel circuit) with the connected bleed machine.
1. System bleeding after replacement of TMC.
1.1 Preparation of actuation
a. Connect new TMC to booster assembly
b. Assemble reservoir to TMC.
c. Assemble brake tubes to TMC brake line ports.
d. Fill reservoir with new DOT 4 brake fluid.
1.2 Conventional bleeding of brake system.
a. Connect bleeder bottle tube to FL caliper bleeder screw.
b. Actuate brake pedal with a pedal force of 150N to 200N.
c. Open bleeder screw until pressure is released, close bleeder screw, then release brake pedal.
d. After pedal release wait 2s until brake fluid is flown into the master cylinder.
e. Repeat this procedure till clear, bubble free brake fluid streams out.
Lead value: 10 to 20 times.
NOTE: Watch brake fluid level in reservoir and refill if necessary (mind the pad wear).
According 1 .2 repeat procedure for caliper Fly, RL and FIR. (only for ESP vehicles).
When manual bleeding in IG ON.
Warning Lamp is ON due to malfunction of pressure sensor.
Erase warning lamp using Hi-scan tool.
There is NO problem when IG is MULE
1.3 Vehicle disconnection
a. Fill reservoir to "MAX" level and mount reservoir cap (mind pad wear)
b. Start engine to generate vacuum in the booster.
c. Check brake pedal travel and pedal feeling.
NOTE: If the pedal travel is too long after the bleeding, check the brake system for leaks, or if O.K., repeat procedure 1.2 (only for ESP
vehicles) Trim the pressure sensor(s) via diagnose.
d. Remove bleeder hoses and retighten wheel bleeder screws to correct torque.
Tightening torque: 7 - 13 Nm (70 - 130 kg-cm, 5 - 9 ft. lbs.)
2. System bleeding after replacement of one (both) TMC pressure sensor(s) (Only for ESP vehicles)
2.1 Preparation of actuation
a. Assemble new pressure sensor(s) to TMC
NOTE: After assembling, trim the new pressure sensor(s) via diagnosis.
b. Fill reservoir with new DOT 4 brake fluid.
2.2 Bleeding conventional brake system see section 1.2
2.3 Vehicle disconnection according to 1.3
3. Bleeding brakes after replacement of the Hydraulic Control Unit (HCU)
NOTE: The repair part HCU is completely filled
3.1 Vehicle preparation
a. Connect bleeder bottle tube to bleed screws of FL and RL caliper and open them.
b. Actuate the brake pedal (-60 mm (2.36 inch)) and secure it by using a pedal support. This closes the TMC central valves and prevents
fluid flowing out of the opened brake system.
c. Close FL and RL caliper bleeder screws and remove bleeder bottle.
d. Remove defective HCU.
NOTE: Remove brake tubes which lead from the HCU to the TMC first and close open ports of the HCU with protection caps
immediately. Then remove brake tubes from HCU to the brakes and close these ports of the HCU with protection caps, too.
e. Install new HCU
NOTE: The new repair part HCU is totally pre-filled. To keep the brake fluid inside the HCU, remove port protection caps of the brake
circuit connections first and assemble these brake tubes. When all brake circuits are connected, remove port protection caps of TMC,ports
