Some vehicles may exhibit a grabbing condition from the rear brakes during the first few brake applications. The condition only occurs after the vehicle has been parked for several hours. ACTION Follow the Service Procedure steps to correct the condition. SERVICE PROCEDURE To service, reduce/minimize moisture intrusion into the rear drum brake assemblies by applying Motorcraft® Silicone Gasket and Sealant to the brake backing plate. 1. Place vehicle on hoist and remove the rear wheels. 2. Remove the rear brake drums and replace the rear linings. Refer to Workshop Manual (WSM), Section 206-02. WARNING Do not breathe dust or use compressed air to blow dust from storage containers or friction components. Remove dust using government-approved techniques. Friction component dust may be a cancer and lung disease hazard. Exposure to potentially hazardous components may occur if dusts are created during repair of friction components, such as brake pads and clutch discs. Exposure may also cause irritation to skin, eyes and respiratory tract, and may cause allergic reactions and/or may lead to other chronic health effects. If irritation persists, seek medical attention or advice. Failure to follow these instructions may result in serious personal injury. 3. Inspect the rear brake assemblies for damaged, missing and/or improperly seated adjuster plug or parking brake cable. 4. Inspect and clean the lining contact area of the brake drum; machine if necessary. 5. Reinstall the rear brake drums and adjust the lining to drum clearance per WSM, Section 206-02. 6. Thoroughly clean the backside of the rear drum brake backing plate to promote proper adhesion of sealant. 7. Apply Motorcraft(R) Silicone Gasket and Sealant to the backside of the rear drum brake backing plate at the following inter[ace areas (Figure 1): ^ Axle Flange ^ Wheel Cylinder ^ Parking Brake Cable ^ Hold Down Pins NOTE AVOID GETTING SEALANT ON THE BRAKE BLEED SCREW AND BRAKE TUBE NUT. 8. Reinstall the rear wheels and torque lug nuts per Workshop Manual, Section 204-04.

BRAKES – REAR BRAKE NOISE- “MOANING/GROANING” FROM REAR BRAKES WHEN COLD ^ NOISE – “MOANING/GROANING” FROM REAR BRAKES WHEN COLD MERCURY: 1999-2001 COUGAR ISSUE Some vehicles equipped with rear disc brakes may exhibit a “moaning/groaning” noise on initial brake application (cold soak). This may be caused by the rear brake pads vibrating in the caliper. Braking performance is not affected by this condition. ACTION Install revised Rear Disc Brake Service kit. Refer to the following Service Procedure for details. SERVICE PROCEDURE 1. Lift and support vehicle. Refer to the appropriate Workshop Manual, Section 100-01. 2. Remove both rear tire assemblies. 3. Remove rear brake pads per instructions in the Workshop Manual, Section 206- 04.4. Remove U-spring from the top of the caliper and replace with L-spring supplied in kit (Figure 1). NOTE THE LEG OF THE L-SPRING FACES THE OUTSIDE OF VEHICLE.5. Remove adhesive backing protection from new pads with C-springs (Figure 2) and install new pads into caliper. Use Pads XS7Z-2200-M for vehicles without

Remote release handle Parking brake control Parking brake rear cable and conduit clip (part of 2A635) Parking brake cable bracket Parking brake rear cable and conduit— (LH) Parking brake rear cable and conduit— (RH) Parking brake cable equalizer Front parking brake cable and conduit Front parking brake cable clip The parking brake system is actuated when the parking brake control (2780) is depressed. The parking brake control applies tension to the front parking brake cable and conduit (2853) and parking brake cable equalizer (2A602). The parking brake cable equalizer is coupled to the RH parking brake rear cable and conduit (2A635) and the LH parking brake rear cable and conduit. The respective rear brake assemblies are then applied. The rear wheel brake assembly contains a cable-actuated parking brake assembly. The parking brake releases the rear brakes using a remote release lever incorporated with the parking brake control. If the parking brake control is not fully released, the parking brake signal switch will illuminate the brake warning light. The parking brake signal switch is mounted on the parking brake control. The switch is held in place by a self-tapping screw and aligned with a locater pin. The drum brake parking brake system is self-adjusting, therefore cable tension does not need to be adjusted.

Removal 1. Raise vehicle on hoist. Refer to Section 00-02. 2. Remove rear wheel and tire assembly. 3. Remove rear stabilizer bar link and bushing link nuts at both ends of rear stabilizer bar (5A772) . Rotate bar up and out of the way. 4. Disconnect parking brake rear cable and conduit (2A635) at rear disc brake caliper (2553) . 5. Install three Rotunda Spring Cages 086-00031 or equivalent to rear spring as follows: a. Install one spring cage without an adjuster link to the inboard side (the innermost “bend” of the rear spring (5560) ). b. Install two more spring cages, with adjusters, at 120 degree angles to the previously installed cage. Spring, Rear 6. Place a transmission jack or suitable stand under the rear suspension arm and bushing (5500) as far outboard as possible. 7. Support the rear wheel knuckle (5A969) assembly by wiring the rear suspension arm and bushing to the body. 8. Remove lower rear shock absorber mounting bolt, washer and nut. 9. NOTE: Rear suspension arm and bushing must not be lowered until pivot bolts are loose. Do not attempt to remove plastic cap on front pivot nut. Loosen both inboard pivot bolts on rear suspension arm and bushing . 10. Remove two bolts and nuts retaining rear suspension arm and bushing to rear wheel knuckle . 11. Lower the rear suspension arm and bushing by lowering jack. Ensure spring cages properly seat on rear spring as rear suspension arm and bushing is dropped. 12. Remove jack, lower rear suspension arm and bushing down fully by hand and remove rear spring with cages in place. 13. Remove rear spring center mounting insulators (5741) , if necessary. 14. If spring cages are to be removed for installation on rear spring , use Coil Spring Compressor D78P-5310-A or equivalent to compress rear spring and remove cages. Rear spring center mounting insulator should be installed on rear spring before installing rear spring in tool to prevent slipping of plates.

During assembly, some wheel speed sensors may have been improperly installed and do not seal the hub assembly. Water may enter the hub assembly and damage the wheel bearing. In areas where road salt is used, the wheel bearings may corrode, which may cause the wheel to separate and fall off, increasing the risk of a crash. CORRECTIVE ACTION Inspect both rear ABS wheel speed sensors and their O-rings. If an ABS wheel speed sensor or O-ring is damaged, replace the damaged part and the hub bearing unit on that wheel. REPAIR PROCEDURE 1. 2. 3. 4. Raise the vehicle on a lift. Remove the rear wheels. Remove both rear ABS wheel speed sensors. Inspect the rear ABS wheel speed sensors and their O-rings. • If a rear ABS wheel speed sensor O-ring is damaged (cut, torn, pinched, or flattened), replace the O-ring and the corresponding rear hub bearing unit, then go to step 5. DAMAGED O-RINGS: O-ring is pinched. • If the rear ABS wheel speed sensor tip has any physical damage, remove the original sensor assembly, replace the corresponding rear hub bearing unit(s), and connect the new sensor’s wire harness. Then go to step 5. – Refer to page 18-34 (with disc brakes) or 18-36 (with drum brakes) of the 2006–07 Civic Service Manual, or – Online, enter keyword HUB, then select Rear Knuckle/Hub Bearing Unit Replacement from the list. O-ring is rolled out of the groove and flattened. -Refer to page 18-34 (with disc brakes) or 18-36 (with drum brakes) of the 2006–07 Civic Service Manual, or – Online, enter keyword HUB, then select Rear Knuckle/Hub Bearing Unit Replacement from the list. • If the rear ABS wheel speed sensors and their O-rings are OK, go to step 5. 5. Lubricate the ABS wheel speed sensor O-ring and the sensor hole in the knuckle with multi-purpose grease.
