Brake Bleeding: Service and Repair

BRAKE FLUID AIR BLEEDING

CAUTION:
- Keep the fluid level in the reservoir at 3/4 full or more during the air bleeding.
- Be careful not to spill brake fluid on any painted surfaces. Rinse off any spilled brake fluid with water.
- Begin air bleeding with the brake equipment that is furthest from the master cylinder.

Specified fluid
- SAE J1703 or FMVSS116 DOT-3

1. Remove the bleeder cap on the brake caliper or wheel cylinder, and attach a vinyl tube to the bleeder screw.

2. Place the other end of the vinyl tube in a clear container and fill the container with fluid during air bleeding.

3. Working with two people, one should pump the brake pedal several times and depress and hold the pedal down.

4. While one technician depresses the brake pedal, another technician loosens the bleeder screw using any commercially available flare nut wrench, drain out any fluid containing air bubbles, and then tighten the bleeder screw.






Tightening Torque
- Front: 6.9-9.8 Nm {71-99 kgf-cm, 62-86 in-lbf}
- Rear: 6.9-8.8 Nm {71-89 kgf-cm, 62-77 in-lbf}

5. Repeat Steps 3 and 4 until no air bubbles are seen.

6. Perform air bleeding in the order of the procedure described above for all brake calipers or wheel cylinders.

7. After air bleeding, inspect the following:

- Brake operation
- Fluid leak(s)
- Fluid level Testing and Inspection
