ISSUE:
The use of petroleum-based grease as a lubricant in servicing disc brakes is no longer acceptable because it may be incompatible with the rubber material used in the disc brake system. If petroleum-based grease is used to lubricate any part of the disc brake system. it could cause rubber parts to swell if lubricant contacts the rubber material.

ACTION:
Refer to the following Servicing Procedures for details.

DISC BRAKE SERVICING

CAUTION:
DO NOT USE PETROLEUM-BASED SERVICE GREASE (SUCH AS FORD DISC BRAKE CALIPER SLIDE GREASE D7AZ-19590A) TO LUBRICATE DISC BRAKE CALIPER SLIDE PINS OR RUBBER DUST BOOTS. PETROLEUM-BASED GREASE MAY CAUSE EPDM RUBBER TO SWELL.

When servicing any disc brakes, lubricate necessary components by applying Silicone Brake Caliper Grease and Dielectric Compound (D7AZ-19A331-A (Motorcraft WA-10)) or an equivalent silicone compound meeting Ford Specification ESE-M1C171-A. Refer to the appropriate Service Manual for specific service details.

When servicing drum brakes, apply Silicone Brake Caliper Grease and Dielectric Compound (D7AZ-19A331-A (Motorcraft WA-10)) or an equivalent silicone compound meeting Ford Specification ESE-M1C171-A to the contact points between the brake shoes and the drum backing plates for lubrication.

NOTE:
DISC BRAKE CALIPER SLIDE GREASE D7AZ-1959O-A SHOULD NO LONGER BE USED FOR DISC BRAKE CALIPER SLIDE LUBRICATION.
