Bleeding The Brakes - Ford Ranger Maintaince And Repair Manual

To install:
9. Install the new line or hose, starting with the end farthest from the master cylinder. Connect the other
end, then confirm that both fittings are correctly threaded and turn smoothly using finger pressure.
Make sure the new line will not rub against any other part. Brake lines must be at least 1/2 in. (13mm)
from the steering column and other moving parts. Any protective shielding or insulators must be
reinstalled in the original location.
Make sure the hose is NOT kinked or touching any part of the frame or suspension after installation. These
conditions may cause the hose to fail prematurely.
10. Using two wrenches as before, tighten each fitting.
11. Install any retaining clips or brackets on the lines.
12. If removed, install the wheel and tire assemblies, then carefully lower the vehicle to the ground.
13. Refill the brake master cylinder reservoir with clean, fresh brake fluid, meeting DOT 3 specifications.
Properly bleed the brake system.
14. Connect the negative battery cable.

Bleeding The Brakes

Vehicles with 4−wheel anti−lock brakes require an Anti−lock Brake Adapter (T90P−50−ALA) and Jumper
(T93T−50−ALA) in order to bleed the master cylinder and the Hydraulic Control Unit (HCU). Failure to do
so will trap air in the HCU unit, eventually causing a spongy pedal. The tools are not required for caliper or
wheel cylinder bleeding procedures.
When any part of the hydraulic system has been disconnected for repair or replacement, air may get into the
lines and cause spongy pedal action (because air can be compressed and brake fluid cannot). To correct this
condition, it is necessary to bleed the hydraulic system after it has been properly connected to be sure all air is
expelled from the brake cylinders and lines.
When bleeding the brake system, bleed one brake cylinder at a time, beginning at the cylinder with the longest
hydraulic line (farthest from the master cylinder) first. ALWAYS Keep the master cylinder reservoir filled
with brake fluid during the bleeding operation. Never use brake fluid that has been drained from the hydraulic
