#### REMOVAL & INSTALLATION

NOTE: All 4 front brake pads MUST ALWAYS be replaced as a complete set. Bleed the brake system only if necessary. Refer to the necessary illustrations as guide for this repair.

##### Type N22 Series Disc Brake Assembly

1. Raise and support the front of the vehicle. Remove the wheels.
2. Remove the retaining clip from the outboard pad.
3. Remove the pad pins retaining the anti-squeal springs.
4. Remove the pads.

   To install:

5. To install, open the bleeder screw slightly and push the outer piston into the cylinder until the dust seal groove aligns with the end of the seal retaining ring, then close the bleed screw. Be careful because the piston can be pushed too far, requiring disassembly of the caliper to repair. Install the inner pad.

6. Pull the yoke to push the inner piston into place. Install the outer pad.
7. Lightly coat the areas where the pins touch the pads, and where the pads touch the caliper (at the top) with grease. Do not allow grease to get on the pad friction surfaces.
8. Install the anti-squeal springs and pad pins. Install the clip.
9. Apply the brakes a few times to seat the pads. Check the master cylinder level. Add fluid if necessary. Bleed and adjust the brakes if necessary.

##### Type CL22V Series Disc Brake Assembly

Fig. 6: Exploded view of the CL22V series disc brake assembly

1. Raise the front of the car and support it with safety stands.
2. Unscrew and remove the lower pin bolt (sub pin).
3. Swing the cylinder body upward and then remove the pad retainer, the inner and outer shims and the pads themselves. Do not depress the brake pedal when the cylinder body is in the raised position or the piston will pop out.

   To install:

4. Clean the piston end of the cylinder body and the pin bolt holes. Be careful not to get oil on the rotor.
5. Pull the cylinder body to the outer side and install the inner pad.
6. Install the outer pad, the shim and the pad retainer.
7. Reposition the cylinder body and then tighten the pin bolt to 12–15 ft. lbs.
8. Apply the brakes a few times to seat the new pads. Check the fluid level and bleed and adjust the brakes if required.

##### Type AD22V Series Disc Brake Assembly

1. Remove the road wheel.
2. Remove the lower caliper guide pin. See the accompanying illustration.

   Fig. 8: . . . and rotate the caliper up and away from the rotor. Do not apply the brakes with the caliper in this position!

3. Rotate the brake caliper body upward.
4. Remove the brake pad retainer and the inner and outer pad shims.
5. Remove the brake pads. Do not depress the brake pedal when the caliper body is raised. The brake piston will be forced out of the caliper.

   To install:

6. Clean the piston end of the caliper body and the pin bolt holes. Be careful not to get oil on the brake rotor.
7. Pull the caliper body to the outer side and install the inner brake pad. Make sure both new pads are kept clean!
8. Install the outer pad, shim and pad retainer.
9. Reposition the caliper body and then tighten the guide pin bolt to 23–30 ft. lbs.
10. Apply the brakes a few times to seat the pads (bleed and adjust brakes if necessary) before driving out on the road.

##### Types CL28VB, CL22VB and CL25VB Series Disc Brake Assembly

NOTE: Use this service procedure and illustrations as a guide for all other CL type Series Disc Brake Systems.

1. Raise the vehicle and support it securely. Remove the front wheel. Remove the pin (lower) bolt from the caliper.
2. Swing the caliper body upward on the upper bolt. Remove the pad retainers and inner and outer shims. Do not depress the brake pedal when the cylinder body is in the raised position or the piston will pop out. Avoid damaging the piston seal when removing/installing the pads and retainers.

   To install:

3. Check the level of fluid in the master cylinder. If the fluid is near the maximum level, use a clean syringe to remove fluid until the level is down well below the lip of the reservoir. Then, use a large C-clamp to press the caliper piston back into the caliper, to allow room for the installation of the thicker new pads.

4. Install the new pads, utilizing new shims, in reverse order. Torque the lower retaining bolt to 16–23 ft. lbs. Bleed and adjust the brakes if necessary. Make sure you pump the brakes and get a hard pedal before driving the car!
