Brake Bleeding: Service and Repair
Pressure Bleeding
For pressure bleeding, use a bladder-type bleeder tank only, such as the Rotunda Brake Bleeder 104-00064 or equivalent.
Bleed the longest tubes first on the system being bled. The bleeder tank should contain enough new brake fluid to complete the bleeding operation.
Use High Performance DOT-3 Motor Vehicle Brake Fluid C6AZ-19542-AB or DOT-3 equivalent fluid meeting Ford specification ESA-M6C25-A
for all brake applications. Never reuse brake fluid that has been drained from the hydraulic system. The pressure bleeder tank should be charged with
approximately 69-206 kPa (10 to 30 psi) of air pressure.
1. Clean all dirt from the brake master cylinder filler cap.
2. Remove the brake master cylinder filler cap. Fill the brake master cylinder reservoir with the specified brake fluid. Install the pressure bleeder
adapter tool to the brake master cylinder and attach the bleeder tank hose to the fitting on the adapter. Follow the instructions of the manufacturer
to install the adapter.
CAUTION: To prevent system damage, never exceed 344 kPa (50 psi) pressure.
3. 4.6L only - Bleed brake master cylinder.
4. If the rear disc brake calipers are to be bled, start with LH rear disc brake caliper and attach bleed tube snugly around wheel cylinder bleeder
screw fitting.
5. Open the valve on the bleeder tank to admit pressurized brake fluid into the brake master cylinder reservoir.
6. Submerge the free end of the tube in a container partially filled with clean brake fluid and loosen the wheel cylinder bleeder screw.
7. When air bubbles cease to appear in the fluid at the submerged end of the bleeder tube, close the wheel cylinder bleeder screw. Remove the tube.
Replace rubber dust cap on bleeder screw.
8. Repeat Steps 3 through 6 at RH rear disc brake caliper.
9. Attach a bleed tube to front brake caliper wheel cylinder bleeder screws and repeat Steps 4 through 6, starting at the caliper with the longest brake
tube and ending with the shortest tube.
10. After all calipers have been bled, bleed the brake master cylinder using bleed screws on brake master cylinder.
11. When the bleeding operation is completed, close the bleeder tank valve and remove the tank hose from the adapter fitting.
12. After disc brake service, make sure disc brake pistons are returned to their normal positions and the lining assemblies are properly seated. This is
accomplished by depressing the brake pedal several times until normal pedal travel is established.
13. Remove the pressure bleeder adapter tool from brake master cylinder. Fill the brake master cylinder reservoir. Install the brake master cylinder
filler cap.
