Corrective Procedure
1. Determine that the vehicle was built between the following production dates:
2. Remove the front wheels.
3. Remove the pad protector by prying up the edge of the clip at the center of the pad protector with a screwdriver (Figure 1). Take care not to damage this part as it will be reused during reassembly.
4. While holding the center of the M-clip with a screwdriver. detach the M-clip from the pad and retaining pins (Figure 2). Remove the M-clip and then remove the K-spring with pliers. Discard these parts as new ones are supplied in the brake pad kit.
5. Pull the retaining pins from the caliper assembly (Figure 3). Remove the inner brake pad. Then remove the outer brake pad and anti-squeak shim, which is located between the caliper and the outer pad. Discard the pads and anti-squeak shim.
6. Inspect the brake pad protector and brake pad retaining pins for damage and/or excessive wear. Replace damaged parts as necessary.
7. Inspect the area of the brake caliper piston and dust seal for leaking brake fluid or damage (Figure 4). If necessary, rebuild the caliper following the procedures in the Precis Service Manual.
8. Inspect the brake disc (rotor) for wear, rust, damage or warpage. Resurface the disc if rust, deep scratches, grooves or excess runout are present (see step 10 for runout inspection).
NOTE:
It is important that the front brake discs are equal in size. Therefore, if it is necessary to resurface a front disc, it is important to resurface both discs an equal amount. Where disc replacement is required, replace both discs. Never resurface or replace just one disc. Both front discs should be identical. Refer to the Precis Service Manual for disc removal procedures.
9. If after resurfacing the disc, the disc is thinner than the service limit shown below (Figure 5) or still has grooves and scratches in the surface, the disc must be replaced. When checking the disc thickness, measure the disc at four or more locations.
Service Unit: 11.4 mm (0.45 in.)
Replace the brake disc if the thickness is less than the service limit at one or more locations.
10. Measure the runout of the brake disc.
A. Measure the brake disc runout with a dial gauge placed approximately 5 mm (0.2 in.) from the outer edge (Figure 6).
Standard value: 0.15 mm (0.006 in.) or less
B. If the runout exceeds the standard value, replace the brake disc.
11. Before installing the new brake pads, make certain that all oil, grease or dirt is cleaned from the brake disc.
12. Push the caliper piston into the cylinder so that the new pads and anti-squeak shim can be installed. Insert a steel plate between the piston and the disc to prevent damaging the disc (Figure 7). Install the new brake pads and shim from the brake pad kit (P/N 00947-21030).
NOTE:
The shim must be installed only between the outer pad and the caliper (Figure 8).
13. Reinstall the pad retaining pins, making sure that each pin goes through the outer caliper, anti-squeak shim, both brake pads and into the receiving holes of the inner caliper.
14. Install the new K-spring and M-clip as shown in Figure 8 (spring on inside and clip on outside), making sure that each end of the M-clip goes through the holes in the upper and lower brake pad retaining pins. Make sure that the K-spring is hooked over the Inner pad tab and that the M-clip ear goes through the outer pad locating hole.
15. Install the pad protector in the proper direction as shown in Figure 9. Make sure that the securing tabs are clipped over each of the pad retaining pins.
16. Install the tire/wheel assembly and torque the nuts to the appropriate specifications.
Steel Wheel Aluminum Alloy Wheel

CAUTION:
DO NOT USE AN IMPACT WRENCH TO TIGHTEN THE WHEEL NUTS. THE USE OF AN IMPACT WRENCH MAY RESULT IN OVER-TORQUING, WHICH MAY DAMAGE THE WHEEL NUTS, STUDS AND/OR THE WHEEL ONLY USE A TORQUE WRENCH TO TIGHTEN THE WHEEL NUTS.
17. Make a punch mark above the last VIN digit on the engine compartment ID plate to show that the campaign has been completed for this vehicle (Figure 10).
