As the suspension travels up and down, the emergency brake cable may come in contact with the cable guide and cause the condition as shown in the (left / rear) example photo below. The sound usually goes away over time but, should it persist, use the procedure below to repair. SERVICE PROCEDURE / INFORMATION: REMINDER: Customer satisfaction and retention starts with performing quality repairs. Step 1) Park the vehicle on a flat surface and do not set the parking brake.

Bulletin Number: 06-82-21; Date: 03/16/21 Page 2 of 2 Step 2) With the vehicle on the ground, reach up behind the front of the tire and move the brake cable up and down in an effort to duplicate the squeaking sound. If the sound can be duplicated, proceed to Step 3. If not, continue the diagnosis for the origin and cause of the sound. Step 3) Apply a small amount of neutral detergent (dish detergent e.g. Dawn® or equivalent) to lubricate the cable guide where the cable comes in contact with it as shown here. Road test the vehicle to determine if the sound has been changed or eliminated. If eliminated, proceed to Step 4. If it persists, continue the diagnosis and inspections for the source of the sound elsewhere. Step 4) Use warm water to clean and rinse all the detergent from the cable and guide then dry them thoroughly. Step 5) Apply a small amount of silicone grease (p.n. 004404002, 3M Silicone Paste #08946 or equivalent) to the affected contact area. IMPORTANT NOTES: • NEVER use any petroleum-based grease for this procedure as over time, it will damage rubber components of the brake cable assembly. • When the vehicle is raised on a lift, the position of the contact point will change (move away from the guide) by about 10mm due to the suspension being fully extended. Always keep that in mind when applying the silicone grease. Step 6) Road test to confirm the successful repair and complete the procedure.
