Call Will Tillery @ Roverguy.com - he is the Range Rover expert.
The RRC can be a bit tricky when bleeding the brakes on an ABS equipped vehicle. The service manual suggest the following procedure:
1: Switch off ignition and depressurise system. Ensure ignition remains OFF until instruction 7.
2: Fill fluid reservoir with specified fluid to 'MAX' level.
3: Depress brake pedal slowly and progressively five times, using full pedal stroke. Release pedal five to ten seconds, air bubbles will rise into reservoir.
4: Repeat instruction 3 until some resistance is felt. If no resistance is felt check clevis pin is connected to correct (UPPER) hole in brake pedal.
5: Bleed four front caliper lower (hydrostatic) bleed screws in the conventional manner. In the order: outer bleed screw driver’s side, opposite caliper outer bleed screw, inner bleed crew, inner bleed screw driver’s side. Depress brake pedal slowly and progressively, locking bleed screw at bottom of each stroke.
6: Bleed hydraulic pump - open bleed screw on pump and allow fluid to flow until clear of air bubbles. Do not use bleed bottle, use a clean absorbant cloth to prevent fluid spillage.
7: Bleed accumulator - open bleed screw. If vehicle has ETC, accumulator bleed screw is on top of ETC valve block. Switch on ignition, run pump
for 3-4 secs, switch off and repeat procedure until fluid is clear of air bubbles. Switch off ignition. Close bleed screw.
8: Bleed two hydraulic booster bleed screws. Open one bleed screw, depress brake pedal, switch on ignition, run pump until fluid is clear of air
bubbles. Close booster bleed screw, switch off ignition, release pedal. Repeat for other bleed screw.
9: Bleed power circuit at four calipers in turn. Depress pedal, open bleed screw, (upper bleed screw on front calipers). Switch on ignition, run
pump for 3-4 secs, switch off and repeat procedure until fluid is clear of air bubbles. Switch off ignition, close caliper bleed screw, release pedal.
10: Bleed master cylinder - switch ignition on. System pressure will increase until pump cuts out. If pump does not cut out after running for 45
secs, check system for leaks.
11: Bleed hydrostatic circuit calipers - open one front lower caliper bleed screw. Actuate brake pedal several times, using only lower two thirds of
pedal travel, until fluid is clear of air bubbles. Stop actuation if fluid warning light comes on and allow pressure to build up.
12: Close caliper bleed screw before releasing pedal, repeat for remaining three hydrostatic bleed screws.
13: Check/top up reservoir fluid level.
14: Dry all connections, fully pressurise system, check for leaks. If two full brake applications switch on pump, from fully charged, rebleed system.
Have fun,
