Preparation

WARNING: Before bleeding the brake
system refer to general brake service
practice.

See General Brake Service

Practice

•

During bleed procedure, brake fluid level
must not be allowed to fall below the MIN
level. Keep reservoir topped to the MAX level.

•

To bleed the hydraulic circuits four bleed
nipples are provided, one at each caliper.

•

There are two methods by which air can be
removed from the braking system:-

1. MANUAL BLEED PROCEDURE.
2. PRESSURE BLEED PROCEDURE.

Pressure bleed procedure

Purpose designed equipment for pressure filling and
bleeding of hydraulic systems may be used on Land
Rover vehicles. The equipment manufacturer’s
instructions must be followed and the pressure must
not exceed 4.5 bar.

Manual bleed procedure

Equipment required

•

Clean glass receptacle

•

Bleed hose

•

Wrench

•

Approx 2 litres brake fluid.

Master cylinder bleed

1. Disconnect battery negative lead.
2. Depress brake pedal fully and slowly 5 times.
3. Release the pedal and wait for ten seconds.
4. Air bubbles will rise into the reservoir during

these instructions.

at the pedal.

Complete circuit bleed

1. Disconnect battery negative lead.
2. Fit bleed hose to any caliper bleed screw.
3. Dip free end of bleed hose into brake fluid in

bleed bottle.

4. Open bleed screw of caliper.
5. Depress brake pedal fully several times until fluid

is clear of air bubbles.

6. Keeping pedal fully depressed, tighten bleed

screw, then release pedal.

7. Repeat the above procedure on remaining three

calipers.
