Inspection Use Rotunda Brake/Clutch/Service Vacuum 091-R0001 or equivalent to remove all dust from backing plates and interior of brake drums (1126). Wheel Cylinders 1. Rear wheel cylinders should not be disassembled unless they are leaking. Pull back each rear wheel cylinder dust boot and inspect for leakage. 2. Excessive brake fluid at this point indicates leakage past the piston cups and a need for rear wheel cylinder (2261) overhaul. A slight amount of fluid is nearly always present and acts as a lubricant for the pistons. If evidence of leakage is noted, the rear wheel cylinder should be disassembled, inspected and overhauled. 3. Inspect the rear wheel cylinder bore for scratches and pitting. If the rear wheel cylinder is pitted or has deep scratches, the rear wheel cylinder must be replaced. Brake Drums 1. A brake drum should be visually inspected and measured with Rotunda Brake Drum Micrometer 104- 00046 or equivalent. Before making an inspection or measurement, remove grease, brake fluid, or other contaminants from the brake drum using denatured alcohol. 2. Best shop practice requires measuring every brake drum with a brake drum micrometer regardless of visual inspection. The brake drum micrometer is set to the drum diameter and measures the amount and type of wear. Measure the diameter at various points 45-degrees apart around the brake shoe and lining contact area, and at the bottom of the deepest groove to determine if the brake drum requires replacement. Brake Lining 1. Inspect rear brake shoes and linings (2200) for excessive lining wear or shoe damage. If lining is damaged or worn within 0.79mm (1/32 inch) of the rivet heads on riveted linings, it must be replaced. Replace any rear brake shoe and lining that has been contaminated with oil, grease or brake fluid. Replace rear brake shoe and lining in axle sets only. Never replace just one rear brake shoe and lining of a brake assembly. Replace both primary and secondary shoes. Prior to replacement of lining, brake drum diameter should be checked to determine that brake drum diameter is within specification. If braking surface diameter exceeds specification, the brake drum must be replaced. 2. Check condition of rear brake shoes and linings, retracting spring, hold-down springs, and brake drum for signs of overheating. If rear brake shoe and lining metal parts have a slight blue coloring, indicating overheating, retracting and hold-down springs should be replaced. Overheated springs lose their tension and could allow new rear brake shoe and lining to drag and wear prematurely, if not replaced.

Wheel Cylinder Rear wheel cylinders should be rebuilt in full axle sets only. If one side of the vehicle is done, the other side should also be rebuilt. Rear wheel cylinders should not be disassembled unless they are leaking. Carefully pull lower edges of wheel cylinder boots away from rear wheel cylinder, and note whether interior is wet with brake fluid. Excessive brake fluid at this point indicates leakage past piston cups and a need for rear wheel cylinder overhaul. NOTE: A slight amount of brake fluid is nearly always present and acts as a lubricant for the wheel cylinder piston. It is not necessary to remove the rear wheel cylinder from the backing plate to disassemble, inspect, hone, and overhaul the rear wheel cylinder. Removal is necessary only if the rear wheel cylinder is damaged or scored beyond service. Disassembly 1. Remove the rear brake shoe and lining (2200). Refer to the procedure in this section. 2. On ten-inch brakes, remove the wheel cylinder brake shoe links. 3. Disengage rear wheel cylinder boots from retaining grooves in rear wheel cylinder casting. Remove each wheel cylinder boot and wheel cylinder piston from rear wheel cylinder as an assembly. 4. Remove rear wheel cylinder piston cups and wheel cylinder piston cup spring from wheel cylinder bore. 5. Discard all rubber parts. 6. Remove wheel cylinder bleeder screw from rear wheel cylinder. 7. Wash all parts in clean, denatured alcohol. 8. Inspect pistons for scratches, scoring, or other visible damage. Replace if necessary. Always replace rubber parts. 9. Inspect the rear wheel cylinder bore for score marks or rust. If either condition is present, the rear wheel cylinder bore must be honed. However, the rear wheel cylinder should not be honed more than 0.08mm (0.003 inch) beyond its original diameter. 10. Wash rear wheel cylinder with clean, denatured alcohol after honing, dry it with compressed air. 11. Inspect the bleeder hole to ensure it is free of obstructions. Assembly Use all parts in the wheel cylinder service kit. 1. Apply a light coating of High Performance DOT 3 Brake Fluid C6AZ-19542-AA or equivalent DOT 3 fluid meeting Ford specification ESA-M6C25-A, DOT 3 to all internal parts.

Removal 1. Remove the wheel (1007) and brake drum (1126). 2. NOTE: If the boots are not removed, brake fluid leakage past the cups may go undetected because the boots may seal the fluid in the rear wheel cylinder. If leaks are found, the rear wheel cylinder must be repaired or replaced. Inspect rear wheel cylinder for signs of leaks or presence of rust by removing the boots and inspecting interior surfaces. Water leaking into the rear wheel cylinder past the boots will cause rust to form and may cause the rear wheel cylinder to seize. 3. If no leaks are found, install brake cylinder clamp over the ends of the rear wheel cylinder as shown. 5. Remove the brake shoe adjusting lever cable from the anchor pin, cable guide and adjusting lever. 6. Remove the cable guide from the secondary brake shoe and lining web. 7. Remove the adjusting lever and adjusting lever return spring. 8. Remove the brake shoe adjusting screw spring. 9. Using Hold-Down Spring Tool T73T-2300-A, remove the brake shoe hold-down spring and pin from each rear brake shoe and lining (2200). 10. Remove the brake shoe adjuster assembly. 11. Remove the primary brake shoe parking brake lever link and parking brake link spring.
