Caution

•  Brake fluid will damage painted surfaces. Be careful not to spill any on painted surfaces. In addition, if there is any brake fluid on the wiring harness, the wire insulation may corrode causing a malfunction such as a short circuit. If brake fluid gets on a painted surface or wiring harness, wash and flush it off completely with water immediately.

1.  Switch the ignition off.

2.  Remove the clips.

3.  Set the splash shield out of the way.

4.  Disconnect the brake pipe from the brake hose.

5.  Remove the clip.

6.  Remove the brake hose from the bracket.

Caution

•  When removing the brake pipe, the pipe holder may detach from the body. Remove the brake pipe while pressing the pipe holder to prevent it from detaching from the body. The pipe holder cannot be reused if it detaches from the body.

7.  Detach the brake pipe from the pipe holder.

8.  Install the SST to the brake pipe as shown in the figure.

9.  Bleed the brake line and the SSTs of air. Bleed the air form the SSTs using bleeder screw A.

10.  Connect the M-MDS to the DLC-2.

11.  Select the “BRK_F_P_R” PID.

12.  Start the engine.

13.  Depress the brake pedal, and confirm that the fluid pressure value of the SST (Gauge) and the value shown on the M-MDS are equal.

•  If the fluid pressures are different, replace the DSC HU/CM. (See DSC HU/CM REMOVAL/INSTALLATION.)

14.  After the inspection, remove the SSTs, install the brake hose, clip, and brake pipe to the original positions, and then bleed the air from the brake line. (See BRAKE HOSE (FRONT) REMOVAL/INSTALLATION.) (See BRAKE FLUID AIR BLEEDING.)
