Diagnostic Procedure # 4 - Brake Imbalance

1. Check the rear brakes. Remove the rear wheels and brake drums. Check the cage diameter using the Brake Adjustment Gauge (D81L-1103-A, or equivalent). If either side is out-of-specification, check for proper function of the adjusting mechanism and repair or replace as required.

NOTE:
REFER TO TSB ARTICLE 98-5A-41 FOR ON-VEHICLE ROTOR MACHINING INFORMATION AND ITS REFERENCE TO INSUFFICIENT TURNING MATERIAL.

2. Resurface (turn) both front rotors on-vehicle.

CAUTION:
BE SURE LUBRICANT DOES NOT GET ON THE ROTORS, LININGS, OR CALIPER PISTON BOOTS.

3. Inspect and clean any corrosion buildup under and around the knuckle rail and spring clips. Lubricate between knuckle rail and spring clips with Silicone Brake Caliper Grease and Dielectric Compound (D7AZ-19A331-A).

4. Install the new front matched Brake Linings (F5TZ-2001-BC). Be sure the last three (3) digits of the left inner pad are matched with the last three (3) digits of the right inner pad. Similarly, be sure the last three (3) digits of the left outer pad are matched with the last three (3) digits of the right outer pad. For example, a typical code on the edge of a pad would be 5196 BX NC EE 123 LA. 123 must be matched between the left and right pads.

5. Lightly apply Silicone Brake Caliper Grease and Dielectric Compound where spring clip contacts the brake pad. There are four (4) lubrication points for each brake pad:

^ Upper pad slide area

^ Upper anti-rotation ear

^ Lower pad slide area

^ Lower anti-rotation ear

NOTE:
REFER TO THE APPROPRIATE SERVICE MANUAL, SECTION 06-03, FOR DETAILS.

NOTE:
EVENLY TIGHTEN THE FIVE (5) LUG NUTS (1/2"-20) IN A CRISSCROSS-TYPE PATTERN TO 140 +/- 40 N.m (103 +/- 30 LB-FT). USE DARK BROWN ACCUTORQ(R) SOCKET AS DESCRIBED IN TSB ARTICLE 95-64.

Advise the customer of the "Breaking Your Vehicle In" section in the front of their Owner Guide. This section recommends that the customer avoid sudden stops due to new brake linings. It suggests that the following steps be taken:

^ Watch traffic carefully so that you can anticipate when to stop

^ Begin braking well in advance

^ Apply the brakes gradually

The break-in period for new brake linings lasts for 160 km (100 miles) of city driving or 1,600 km (1,000 miles) of highway driving.
