Brake Fluid (W/ Vsc) -- Bleeding |
- HINT:
- If any work is performed on the brake system or if air in the brake lines is suspected, bleed air from the brake system.
- NOTICE:
- 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.
Using a union nut wrench, disconnect the 2 brake lines from the master cylinder.
 |
Slowly depress and hold the brake pedal.
Cover the outer holes with your fingers, and release the pedal.
 |
Repeat the 2 previous steps 3 or 4 times.
Using a union nut wrench, connect the 2 brake lines to the master cylinder.
- Torque:
- 15 N*m{155 kgf*cm, 11 ft.*lbf}
- NOTICE:
- Use the formula to calculate special torque values for situations where a union nut wrench is combined with a torque wrench (Toyota Fortuner RM000000UYX010X.html).
| 3. BLEED AIR FROM BRAKE LINE |
Remove the bleeder plug cap.
Connect a vinyl tube to the bleeder plugs.
Depress the pedal several times, and then loosen the bleeder plug with the pedal depressed.
When fluid stops coming out, immediately tighten the bleeder plug. Then release the pedal.
Repeat the 2 previous steps until all the air in the brake fluid is gone.
Tighten the bleeder plug.
- Torque:
- for front brake:
- 11 N*m{110 kgf*cm, 8 ft.*lbf}
- for rear brake:
- 10 N*m{102 kgf*cm, 7 ft.*lbf}
Install the cap.
Bleed air from the brake line for each wheel by repeating the above procedures.

| 4. CHECK BRAKE FLUID LEVEL IN RESERVOIR |
Check the fluid level.
If the brake fluid level is lower than the MIN line, check for leaks and inspect the disc brake pads. If necessary, refill the reservoir with brake fluid to the MAX line after repair or replacement.- Fluid:
- SAE J1703 or FMVSS No. 116 DOT3
