On Vehicle Inspection

Disc cleaning before inspection

The rust generated on brake discs of long-term non-operating vehicles is naturally removed under normal driving conditions. However, it can affect the thickness and runout measurements, so for accurate measurements, remove them according to the procedure below.

1.Check the brake disc for rust.

2.Spray with cleaning solution on rusted disc surface.

Cleaning Solution : Water-Detergent [Water : 0.08 gal (300 ml) Detergent : 0.004 gal (15 ml)]

   

Do not use lubricating, oil-based cleaning agents (wax, rust inhibitors). Poor braking performance and risk of fire due to pad friction during braking may occur.

3.Turn the vehicle ON, and then pull the RH paddle shift (A) to enter the regenerative braking mode '0'.

   

The rust of the brake disc can not be removed when in regenerative braking mode in1 or more.

4.Drive the vehicle up to 30 MPH and depress the brake up to stop for complete repeat more than 5 cycles.

5.Clean the brake disc with clean water.

6.Check the brake disc for rust.

7.If rust is not removed, repeat the above procedure again.

Rear brake thickness check

1.Remove the rear wheel and tires.(Refer to Suspension System - "Wheel")

2.Check the brake disc for damage.

3.Measure the brake disc thickness (A) and run-out using the micro meter and dial gauge at least 24 locations on the same column along the lines shown in the figure below.

Rear Brack Disc Thickness (A)17" disc standard : 12 mm (0.47 in.)17" disc limit : 10 mm (0.40 in.)18", 19" disc standard : 20 mm (0.78 in.)18", 19" disc limit : 18 mm (0.70 in.)The difference between each measured thicknessless than 0.015 mm (Column and Radial direction)

4.If the thickness difference between each measuring part is greater than standard, resurface or replace the brake disc.

   

• Resurface the brake disc according to the procedure based on the available machining equipment.

• If the brake disc is less than or equal to the limit, replace the brake disc with a new one.

5.Install the rear wheel and tires.(Refer to Suspension System - "Wheel")

Rear Brake Disc Runout Inspection

1.Remove the rear wheel and tires.(Refer to Suspension System - "Wheel")

2.Install the dial gauge perpendicular to the brake disc's external diameter of 10 mm (0.40 in.) and rotate the disc to measure the run-out.

Brake Disc RunoutService limit : 0.055 mm (0.002 in.) or less.

3.If the brake disc run-out exceeds the limit, resurface or replace the brake disc.

   

• Resurface the brake disc according to the procedure based on the available machining equipment.

• If the brake disc is less than or equal to the limit, replace the brake disc with a new one.

4.Install the rear wheel and tires.(Refer to Suspension System - "Wheel")

Removal

1.Release the parking brake by using the KDS.(Refer to Brake System - "Electric Parking Brake (EPB)")

2.Disconnect the battery negative ( - ) terminal and the service interlock connector.(Refer to Battery Control System - "Auxiliary 12 V Battery - 2WD")(Refer to Battery Control System - "Auxiliary 12 V Battery - 4WD")

3.Remove the rear wheel and tires.(Refer to Suspension System - "Wheel")

4.Disconnect the Electronic Parking Brake (EPB) actuator connector (A).

5.Open the brake caliper body (A) upwards after removing the bolt.

Tightening torque :21.6 - 31.4 N·m (2.2 - 3.2 kgf·m, 15.9 - 23.1 lb·ft)

6.Remove the brake pads (A).

7.Remove the brake pad slider shims (A).

8.Remove the rear brake caliper (A) after removing the bolts and washers.

Tightening torque :98.1 - 117.7 N·m (10.0 - 12.0 kgf·m, 72.3 - 86.8 lb·ft)

   

• Secrue the removed brake caliper (A) using a wire such as cable tie.

• Do not reuse the front brake caliper mounting bolts.

9.Remove the brake disc (A) after removing the screws.

   

Be careful not to damage the hub bolts (A) when removing or installing the brake disc.

   

If the brake disc screw is fixed, place the driver (A) and hit it with a hammer (B).

Installation

1.Install in the reverse order of removal.

   

• Be careful not to interfere with the torque member when assembling the caliper body.

• Turn the brake piston clockwise using SST (09580 - 0U000) to press the brake piston when installing the brake caliper body to torque member.

• Before installing the caliper body, check the position of the piston groove. If the location is fault, press it with the SST.[Normal]

[Fault]

2.Perform "Brake Pad Change Mode" using KDS after installing the rear caliper.(Refer to Brake System - "Electric Parking Brake (EPB)")

3.Depress the brake pedal several times to ensure that the brake pads are correctly positioned, then check operation.

4.Check if the parking brake is operating normally.
