Q: How to Service and Repair a Brake Caliper on Ford Mustang?
A: Service and repair of the brake caliper starts with taking out the disc brake caliper followed by draining all brake fluid from the system. Force out the pistons by using low air pressure at the caliper fluid port together with a wood block placed between the caliper bridge and caliper pistons. The block of wood along with the caliper pistons should be discarded after piston extraction while also discarding the piston seals boots bleed screw and cap. Caliper bore honing must be avoided when assembling the caliper since pistons for honed bores are unavailable. The cleaned caliper pistons and caliper need thorough inspection to detect surface irregularities, scoring, or wear before replacing any damaged units. Use Metal Brake Parts Cleaner F3AZ-19579-SA or its equivalent brand which satisfies Ford requirements to clean caliper bores until boroscope quality is reached. Replace the disc brake caliper with a new one when the caliper bores demonstrate corrosion or excessive scoring. The clean High Performance DOT 3 Brake Fluid C6AZ-19542-AB along with its equivalent DOT 3 fluid that matches Ford specification ESA-M6C25-A should be used to lubricate caliper pistons and piston seals. Position the piston seal and piston boot onto the piston before you press the caliper piston into the bore being cautious of seal damage. The final step includes installation of fresh bleed screw and cap followed by reinstallation of the disc brake caliper.
Q: How to Ensure Proper Brake Caliper Maintenance on a Ford Ranger?
A: Starting brake caliper service and repair requires the exclusive use of Ford High Performance DOT 3 Motor Vehicle Brake Fluid C6AZ-19542-AB or an equal that fulfills ESA-M6C25A Ford specification because any different fluid will damage the brake system permanently and disable vehicle stopping ability. Handle brake fluid with care since exposure to eyes requires immediate flushing with running water for 15 minutes followed by seeking medical attention. Also wash hands thoroughly after use. Drinking water to cause vomiting then going to seek urgent medical assistance in case of fluid ingestion. The immediate application of water serves to protect painted and plastic areas from brake fluid spills. Proceed with brake assembly by taking out the disc brake caliper followed by fluid draining from the system. Secure the caliper in a vise before using a block of wood to separate the caliper bridge from the pistons through low air pressure applied to the fluid port which removes the pistons for discarding their seals and boots. Do not hone caliper bores because pistons work only with smooth bores but excessive bore damage requires an entire caliper replacement. Installation requires new brake component parts because piston seals and dust boots should never be reused and drained brake fluid must remain unused after being left in open containers. Insert approved brake fluid as lubrication on the piston boot while also applying it to caliper piston and piston seal and cylinder bores. To install caliper pistons place the piston seat with boot first before carefully inserting the piston properly and pressing it into the bore. The disc brake caliper needs to be replaced after finished work.
Q: How to Disassemble and Assemble a Brake Caliper for Service and Repair on Ford Explorer?
A: A correct braking caliper service starts with removing the rear disc brake caliper along with draining all brake fluid. Secure the caliper in a vise before proceeding to push out the piston by directing air through the fluid port with low pressure while placing a block of wood on the caliper bridge to create a resting point between the caliper bridge and the piston. After dumping the block you can extract the piston but throw out the piston seal and dust boot prior to cylinder bore honing since pistons are unavailable for honed cylinder bores. An excessive score or corrosion in the bore will require a new rear disc brake caliper installation. The assembly procedure includes new piston seals and dust boots along with avoiding used brake fluid during installation. Use High Performance DOT 3 Motor Vehicle Brake Fluid C6AZ-19542-AB or an equivalent fluid that meets Ford specification ESA-M6C25-A to lubricate the cylinder bore and piston seal as well as the rear disc brake piston and dust boot. Install the piston seal and dust boot slowly while taking care to avoid damage, then position the rear disc brake piston and finally the rear disc brake caliper.
