Brake System Bleeding
The preferred method for bleeding air out of the brake hydraulic system is to use a
pressure-type brake bleeder. Follow the manufacturers directions for using the bleeder.
To bleed the brakes manually, proceed as follows:
1. Fill the master cylinder in the surge actuator with fresh DOT 3 brake fluid. Re-
move the two 5 /
16
" hex head bolts that hold the lever guides and emergency lever
spring. Remove the lever guide and emergency lever spring. Using short strokes, pull
forward on emergency lever until all bubbling stops inside the master cylinder.
2. Install a bleeder hose on the bleeder screw of the left wheel cylinder (left rear if
tandem axle). You should always begin the bleeding operation on the wheel cylinder
that is farthest from the master cylinder. Have the loose end of the hose submerged in
a glass container of brake fluid so that you can observe bubbling.
3. Loosen the bleeder screw one turn and operate the breakaway lever slowly until
all bubbling stops. Close the bleeder screw securely.
4. Check the fluid level in the master cylinder reservoir and replenish as necessary
between wheel cylinder bleedings.
5. Using the same procedure move to the right brake (or right rear if tandem) and
bleed it; for tandem trailers then bleed the left front brake next, and finish with the right
front brake.
6. Fill the reservoir to within 3 /
8
" below the top and replace filler cap securely. Rein-
stall the lever guides and emergency spring with the two bolts that were removed ear-
lier.
