Mazda 3 Service Manual: Rear Brake (Disc) Removal/Installation

CAUTION:

• If the brake hose is installed to the caliper on the vehicle, the tool cannot be installed correctly resulting in brake fluid leakage due to improper installation. Therefore, remove the caliper and brake hose as a single unit when removing the caliper or brake hose, and tighten the brake hose to the caliper to the specified torque, then install the caliper and brake hose as a single unit when installing to the vehicle.

1. Remove in the order indicated in the table.

2. Install in the reverse order of removal.

3. After installation, pump the brake pedal a few times and inspect the following:

• Parking brake lever stroke

• Brake drag

Caliper and Brake Hose Removal Note

1. Remove the caliper and brake hose from the vehicle as a single unit.

Brake Hose Installation Note

1. Secure the caliper to the vise and install the brake hose to it.

CAUTION:

• Insert a protective plate into the vise opening so as not to damage the caliper.

2. Tighten the brake hose to the specified torque.

Tightening torque

• 26—30 N·m {2.7—3.0 kgf·m, 20—22 ft·lbf}

Caliper and Brake Hose Installation Note

1. Clean the exposed area of the piston.

2. Install the SST

(49 F043 002) to the SST

(49 B043 005).

3. Align the SST

projection to the piston groove.

4. Rotate part A on the SST

in the direction of the arrow and secure the SST

to the caliper.

5. Rotate the SST

in the direction of the arrow and push the piston completely into the caliper.

NOTE:

• Even with the piston completely pushed in, the top of the piston projects from the dust seal by approximately 2 mm

  {0.09 in}

  .

6. Rotate part A on the SST

in the direction of the arrow using the tool and remove the SST

from the caliper.

7. Install the caliper and brake hose to the vehicle as a single unit.

Retaining Clip Installation Note

1. Temporarily install the retaining clip to the caliper and mounting support as shown in the figure.

2. Secure the retaining clip so that part A does not slip off from the caliper while installing part B to the mounting support.

3. Verify that the retaining clip is securely installed to the caliper and the mounting support.

Clip and Brake Pipe Installation Note

1. Install the brake hose to the vehicle-side bracket and secure it using a clip.

2. Verify that the brake hose is not twisted.

3. Tighten the brake pipe to the specified torque using a commercially available flare nut wrench.
