The procedure for brake pad service requires first protecting against brake fluid exposure since it contains polyglycol ethers and polyglycols so always avoid eyes contact and wash hands thoroughly post-work. People whose eyes encounter brake fluid should immediately flush them with running water for 15 minutes then visit a doctor for continuing irritation. Consumers must drink water followed by vomiting induction before seeking urgent medical help when exposed to ingestion. It becomes necessary to drain brake fluid from the
Brake Master Cylinder to the extent that it will cover the fluid displacement that occurs when the caliper piston reaches the bottom of the caliper bore when installing new pads. Rise the vehicle until it is stable before you take away the tire wheel assembly. The installation process requires detachment of speed sensor wiring from the front brake hose when necessary before removing the two disc
Brake Caliper bolts. The disc brake caliper needs to stay clear of the front brake hose and must be supported by wire fastened to a suitable underbody object. Take out the disc brake caliper from the front wheel spindle (E-150) but remove it from the front disc brake caliper anchor plate for (E-250 E-350 E-450). A disc brake caliper should be inspected for fluid leaks because leaky components need replacement or rebuilding. Pad thickness inspection requires that worn pads not surpass the established threshold measured from the metal backing plate or rivets. The pad inspection process must verify-pad cleanliness because installation of pads with oil or grease contaminants should be avoided while checking the
Brake Disc and hub for minimum dimensions which require replacement if they fall under the minimum specifications. The caliper piston does not need bottoming when using original pads but applying a C-clamp along with a pad will push the piston down when installing new pads. The rubber caliper sleeve boots need a lubricant substitute for petroleum-based products; use Silicone Brake Caliper Grease and Dielectric Compound D7AZ-19A331-A (Motorcraft WA-10) or an equivalent silicone compound that meets Ford specification ESE-MIC171-A. After the disc brake caliper is installed in either the front wheel spindle (E-150) or front disc brake caliper anchor plate (E-250, E-350, E-450) install and tighten the disc brake caliper bolts. To complete the installation process both front brake hose speed sensor wiring should be reconnected before installing the tire and wheel assembly.
