Disc brake pads must be renewed on BOTH front wheels at the same time – never renew the pads on only one wheel, as uneven braking may result. Although genuine Ford linings are asbestos-free, the dust created by wear of non-genuine pads may contain asbestos, which is a health hazard. Never blow it out with compressed air, and don’t inhale any of it. DO NOT use petroleum-based solvents to clean brake parts; use brake cleaner or methylated spirit only. DO NOT allow any brake fluid, oil or grease to contact the brake pads or disc.
