Brake System - General Information - Brake System Bleeding
General Procedures
WARNING: Do not allow brake fluid to come into contact with eyes or skin.
• CAUTIONS:
Brake fluid can damage paintwork, if spilled wash off immediately with plenty of clean water.
Use only correct grade of brake fluid. If an assembly fluid is required use ONLY brake fluid. Do NOT use mineral
oil, i.e. engine oil etc.
Thoroughly clean all brake calipers, pipes and fittings before commencing work on any part of the brake system.
Failure to do so could cause foreign matter to enter the system and cause damage to seals and pistons which will
seriously impair the efficiency of the brake system. To ensure the brake system efficiency is not impaired the following
warnings must be adhered to :-
DO NOT use any petroleum based cleaning fluids or any proprietary fluids containing petrol.
DO NOT use brake fluid previously bled from the system.
DO NOT flush the brake system with any fluid other than the recommended brake fluid. The brake system should
be drained and flushed at the recommended service intervals. Cover all electrical terminals carefully to make
absolutely certain that no fluid enters the terminals and plugs.
Cover all electrical terminals carefully to make absolutely certain that no fluid enters the terminals and plugs.
During bleed procedure, brake fluid level must not be allowed to fall below the MIN mark. Keep reservoir topped
up to the MAX mark.
To bleed the hydraulic circuits, four bleed nipples are provided, one at each caliper.
1. There are two methods by which air can be removed from
the braking system:
1. MANUAL BLEED PROCEDURE
2. PRESSURE BLEED PROCEDURE
2. Pressure bleed procedure
1. Purpose designed equipment for pressure filling and
bleeding of hydraulic systems may be used on Land
Rover vehicles . The equipment manufacturers
instructions must be followed and the pressure must
not exceed 4.5 bar, 65lb/in.
3. Manual bleed procedureEquipment required
1. Clean glass receptacle
2. Bleed hose
3. Wrench
4. Approx. 2 litres (3 pts) brake fluid
4. Master cylinder bleed
1. Disconnect battery negative lead
2. Depress brake pedal fully and slowly 5 times.
3. Release pedal and wait 10 seconds.
4. Repeat until firm resistance is felt at the pedal.
5. Complete circuit bleed
1. Disconnect battery negative lead
2. Fit bleed hose to caliper bleed screw.
3. Dip free end of bleed hose into brake fluid in bleed
bottle.
4. Open bleed nipple.
5. Depress brake pedal fully several times until fluid is
clear of air bubbles.
6. Keeping pedal fully depresses, tighten bleed nipple
then release pedal.
7. Repeat procedure for remaining calipers.
8. Fit bleed screw protection caps.
9. Check/top-up fluid level when bleeding is complete.

3. NOTE: On 110/130 vehicles ventilated discs are fitted as
standard.
Tap disc to separate from hub.
Installation
1. Locate disc to hub.
2. Apply Loctite 270 to disc bolts and tighten to 73 Nm (54
lbf.ft).
3. Check total disc runout with a dial indicator, this must not
exceed 0,15 mm, 0.006 in. If necessary reposition disc.
4. Instal hub assembly.
For additional information, refer to:
Front Wheel Bearing and
Wheel Hub
(204-01 Front Suspension, Removal and
Installation).
5. Disc reclamation
6. NOTE: The disc MUST BE renewed if the minimum running
thickness stamped on the disc is recorded.
Check disc thickness. This dimension may be machined to
minimum thickness of 12 mm (0.47 in.) - solid discs, 22 mm
(0.90 in) - ventilated discs. Machine equal amount off each
face.
