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-19590-A) 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.
DRUM BRAKE SERVICING
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-19590-A SHOULD NO LONGER BE USED FOR DISC BRAKE CALIPER SLIDE LUBRICATION.
I will contact the ford dealer tommoro to see If I can get some of this brake lube.
