- Remove some brake fluid from the master cylinder.
- Raise the front of the vehicle, and support it with safety stands in the proper locations (see «LIFT AND SUPPORT POINTS»(ref-290856-S03262290762008072200000) ).
- Remove the front wheels.
- Remove the flange bolt (A), and pivot the caliper (B) up out of the way. Check the hose and pin boots for damage and deterioration.
- Remove the pad springs (A) from the brake pads.
- Remove the pad shims (A) and brake pads (B).
- Remove the pad retainers (A). NOTE: The upper and lower pad retainers are different. During installation, make sure the pad retainers are in proper positions.
- Clean the caliper bracket (B) thoroughly; remove any rust, and check for grooves and cracks. Verify that the caliper pins (C) move in and out smoothly. Clean and lube if needed.
- Inspect the brake disc, and check for damage and cracks (see «FRONT BRAKE DISC INSPECTION»(ref-290813-S05781846032008072200000) ).
- Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the retainers on their mating surfaces against the caliper bracket.
- Install the pad retainers. Wipe excess assembly paste off the retainers. Keep the assembly paste off the brake discs and brake pads.
- Mount the brake caliper piston compressor tool (A) on the caliper body (B).
- Press in the piston with the brake caliper piston compressor so the caliper will fit over the brake pads. Make sure the piston boot is in position to prevent damaging it when pivoting the caliper down. NOTE: Be careful when pressing in the piston; brake fluid might overflow from the master cylinder's reservoir. If brake fluid gets on any painted surface, wash it off immediately with water.
- Remove the brake caliper piston compressor tool.
- Apply a thin coat of M-77 assembly paste (P/N 08798-9010) to the pad side of the shims (A), the back of the brake pads (B) and the other areas indicated by the arrows. Wipe excess assembly paste off the pad shims and brake pads. Contaminated brake discs or brake pads reduces stopping ability. Keep grease and assembly paste off the brake discs and brake pads.
- Install the brake pads and pad shims correctly. Install the brake pad with the wear indicator (C) on the bottom inside. If you are reusing the brake pads, always reinstall the brake pads in their original positions to prevent a momentary loss of braking efficiency.

- Add brake fluid as needed.
- After installation, check for leaks at hose and line joints or connections, and retighten if necessary. Test-drive the vehicle, then check for leaks (see «BRAKE HOSE AND LINE INSPECTION»(ref-290813-S04805048392008072200000) ).

- If the brake disc is beyond the service limit, refinish the brake disc with a commercially available on-car brake lathe. Max. refinishing limit: 21.0 mm (0.83 in.) NOTE: If the brake disc is beyond the service limit for refinishing, replace it (see «FRONT BRAKE DISC REPLACEMENT»(ref-290813-S12413789532008072200000) ). A new brake disc should be refinished if its runout is greater than 0.04 mm (0.0016 in.).
- Install the brake pads (see «REPLACEMENT»(ref-290813-S39496367432008072200000) ).

Replace the brake disc if the smallest measurement is less than the max. refinishing limit. Brake disc thickness: Standard: 22.9-23.1 mm (0.90-0.91 in.) Max. refinishing limit: 21.0 mm (0.83 in.) Brake disc parallelism: 0.015 mm (0.0006 in.) max. NOTE: This is the maximum allowable difference between the thickness measurements.
- If the brake disc is beyond the service limit for parallelism, refinish the brake disc with a commercially available on-car brake lathe. NOTE: If the brake disc is beyond the service limit for refinishing, replace it (see «FRONT BRAKE DISC REPLACEMENT»(ref-290813-S12413789532008072200000) ).

- Remove the master cylinder (see «MASTER CYLINDER REPLACEMENT»(ref-290813-S29779195282008072200000) ).
- Set the pushrod adjustment gauge (A) on the master cylinder body (B), push in the center shaft (C) until the top of it contacts the end of the secondary piston (D) by turning the adjusting nut (E).
- Without disturbing the center shaft's position, install the pushrod adjustment gauge (A) backwards on the booster.
- Install the master cylinder nuts (B), and tighten them to the specified torque.
- Connect the booster in-line with a vacuum gauge (C) 0-101 kPa (0-760 mmHg, 0-30 in.Hg) to the booster's engine vacuum supply, and maintain an engine speed that will deliver 66 kPa (500 mmHg, 20 in.Hg) vacuum.
- With a feeler gauge (A), measure the clearance between the gauge body and the adjusting nut (B) as shown. If the clearance between the gauge body and the adjusting nut is 0.4 mm (0.02 in.), the pushrod-to-piston clearance is 0 mm. However, if the clearance between the gauge body and the adjusting nut is 0 mm, the push rod-to-piston clearance is 0.4 mm (0.02 in.) or more. Therefore it must be adjusted and rechecked. Clearance: 0-0.4 mm (0-0.02 in.)
- If the clearance is incorrect, loosen the star locknut (A), and turn the adjuster (B) in or out to adjust. Adjust the clearance while the specified vacuum is applied to the booster. Hold the yoke (C) while adjusting.
- Tighten the star locknut securely.
- Remove the pushrod adjustment gauge (D).
- Check the pushrod length (A) as shown below if the booster is removed. If the length is incorrect, loosen the pushrod locknut (B), and turn the yoke (C) in or out to adjust.
- Install the master cylinder (see «MASTER CYLINDER REPLACEMENT»(ref-290813-S29779195282008072200000) ).
