Thread: Manually bleeding brakes on D2

There is a method where you bridge one of the relays to run the ABS pump,Im sure somebody will help with how to do it.
I think a spongy pedal is a D2 "feature" I have pressure bled mine several times and it always is the same.
If you have a Nanocom,or can get the use of one,it will do the pressure bleeding,quite handy

This document from the Meritor Wabco contains every permutation of the bleeding procedure for the D-Type ABS system, including pressure bleed/fill:

You'll get the best results doing the hawkeye/nanocom bleed routine, but a lot of people get acceptable results with other methods.

The bridging the abs relay replicates part of the diagnostic tool bleed in that it runs the abs pump. The other portions of the diagnostic bleed activates the inlet, outlet and shuttle valves to ensure a complete bleed of the modulator.

With the brake system in good shape you should get a reasonable pedal. The early D2's tend to be a bit soft in pedal feel and the later D2a's had changes to master cylinder, callipers and abs programming to help improve the feel.

I did the 24,000 miles or 2 years brake fluid renewal according to the Haynes manual, and glad I did, the old fluid was like mud. One thing the manual said , "" For brake hydraulic components upstream of the ABS modulator [ including the modulator itself] Land Rover insist the system be bled using their Testbook dedicated test equipment. " Bob

But RAVE doesn't say that. The only unusual thing in RAVE is that the bleeding sequence is reversed to usual, it says to do the fronts first.

I have worked out that perhaps one of the reasons for the soft pedal is the EBD.
If you touch the brakes , then off and quickly back on, the EBD activates and you have little travel and much more braking for the same pressure.

Maybe it needs some travel to calculate the velocity of the foot descending, or maybe it is a bit of pad knockback as well.
