2004 Ford Ranger Brake Caliper Parts Questions & Experts Answers

• Q: How to service and repair the brake caliper on 2004 Ford Ranger?

  A: When servicing the brake caliper use only Ford High Performance DOT 3 Motor Vehicle Brake Fluid C6AZ-19542-AB or its Esa-M6C25A equivalent equivalent. Using any other fluid can lead to permanent damage because it will disable the brakes operation. Users should treat brake fluid with caution because eye exposure leads to irritation so they should immediately flush eyes with running water for 15 minutes and get professional help if eye discomfort lasts longer than 15 minutes. Handwashing is required after fluid contact for complete rinse. Ischemic poisoning from fluid ingestion requires you to drink water to trigger vomiting before obtaining swift professional medical assistance. Any surface with painted or plastic material requires immediate water washing when brake fluid accidentally spills onto it. The disc brake caliper must be removed first before draining residual brake fluid from the system. You should secure the caliper in a vise before you remove its pistons by using a block of wood on the caliper bridge to separate the pistons and then use low air pressure through the fluid port to push out these components for final boot and seal disposal. The caliper bores must not receive honing treatment because pistons work only with unhoney bores while severely damaged bores require replacement of the entire caliper. The piston seals and dust boots must always be replaced during assembly and brake fluid must come from sealed containers without draining. Pharmacological brake fluid serves as a lubricant for both piston boot and caliper piston before being used to lubricate piston seal and cylinder bore surfaces. Slide the piston seal along with the boot into its place before forcing the caliper piston into the bore without applying force that would damage the seal. Finally replace the caliper into its original position.
