Brake Bleeding: Service and Repair
Electronic Stability Control (ESC)
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 DOT4 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 FR, RL and RR.
(Only for ESC 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 OFF
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 ESC vehicles) Trim
the pressure sensor(s) via diagnose.
d. Remove bleeder hoses and retighten wheel bleeder screws to correct torque.
Tightening torque: 7-13 N.m (70-130 kg.cm, 5-9 lb-ft)
2. System bleeding after replacement of one (both) TMC pressure sensor(s)
(Only for ESC vehicles)
2.1 Preparation of actuation
1)
a. Assemble new pressure sensor(s) to TMC
NOTE:
After assembling, trim the new pressure sensor(s) via diagnosis.
b. Fill reservoir with new DOT4 brake fluid.
2.2 Bleeding conventional brake system
See section 1.2
2.3 Vehicle disconnection according to 1.3
