BRAKE SYSTEM
NOTE:
It may be advantageous to bleed the entire system
with the engine running for booster fitted vehicle.
4. Work on brake pedal for fullest strokes, till pedal
feels hard. Hold the brake pedal
.
5. Open the bleed screw by 1/2 to 3/4 of a turn,
sufficient to allow the brake fluid to flow freely and
till your foot touches the floor.
6. Retighten the bleed screw and again start pumping
brake pedal.
7. There should be an interval of 3 to 4 seconds
before making the next stroke. This action should
be repeated until bubbles of air cease to appear at
the end of the bleed tube.
8. Once the clear flow of brake fluid flows through
tube, tighten the bleed screw to specified torque
and refit dust cap.
TIGHTENING TORQUE FOR BLEED SCREW
NUT = 0.5 - 0.8 Kg-m
CAUTION:
Over tightening of bleed screw leads to breaking of
screw which may cause to replace a wheel cylinder
assembly.
1. Carefully clean all dirt from and around the filler
cap. Check the brake fluid level in the reservoir; it
should be above min. and below max. level. Top
up brake fluid accordingly if found belowmin. level.
2. Before commencing bleeding at each bleed screw,
remove the dust cap and clean thoroughly.
3. Attach the transparent (Vinyl) bleed tube to rear
left bleed screw and
place the other end of the
tube in a clean glass jar containing sufficient
brake fluid to submerge the end of the tube.
NOTE:
Ensure that the fluid level in the tandemmaster cylinder
reservoir does not fall low enough to cause air to be
drawn into the system, throughout the bleeding
operation.
9. Repeat the same procedure on rear right, front left
and front right wheel cylinder respectively.
10.After completion of bleeding, apply the brake pedal
hard and check for any leak at the joints and bleed
screws. Also check the brake pedal for
“sponginess”. If found spongy repeat the complete
procedure of bleeding. If pressure bleeding is done,
the engine need not run (For booster fitted vehicle).
But the sequence of bleeding operation should still
be rear left, rear right, front left and front right only.
