Brake Bleeding: Service and Repair

BRAKE: BRAKE FLUID: BLEEDING

BLEEDING
HINT: If any work is performed on the brake system or if air in brake lines is suspected, bleed air from the brake system.
NOTE: Wash off brake fluid immediately if it comes in contact with any painted surface.





1. FILL RESERVOIR WITH BRAKE FLUID
Fluid:
SAE J1703 or FMVSS No. 116 DOT3
2. BLEED AIR FROM BRAKE MASTER CYLINDER





HINT: If the master cylinder has been disassembled or if the reservoir becomes empty, bleed air from the master cylinder.

(a) Using SST, disconnect the 2 brake lines from the master cylinder.
SST: 09023-00101
(b) Slowly depress and hold the brake pedal.






(c) Cover the outer holes with your finger, and release the pedal.
(d) Repeat the 2 previous steps 3 or 4 times.
(e) Using SST, connect the 2 brake lines to the master cylinder.
SST: 09023-00101
Torque: 15 Nm (155 kgf-cm, 11 ft-lbf) without SST
Torque: 14 Nm (143 kgf-cm, 10 ft-lbf) with SST
HINT: Use a torque wrench with a fulcrum length of 30 cm (11.81 in.).





3. BLEED AIR FROM BRAKE LINE
(a) Remove the bleeder plug cap.
(b) Connect the vinyl tube to the bleeder plug.
(c) Depress the pedal several times, and then loosen the bleeder plug with the pedal depressed.
(d) When fluid stops coming out, immediately tighten the bleeder plug. Then release the pedal.

(f) Tighten the bleeder plug.
Torque: 8.3 Nm (85 kgf-cm, 74 in-lbf)
(g) Install the cap.
(h) Bleed air from the brake line for each wheel by repeating the above procedures.
