I’ve never used the iid for the brake bleeding as I have a pressure bleeding kit and never had any issues not using the iid but I think I will use the iid next time to see how it comparesRange Rover Westminster 4.4 TDV8 what a car

I think its only required if you get the tank dry and air into the ABS
So just do it normally.

Thanks chaps
I’ve bled everything now, only put 1 litre through as it was dark!
Will run some more through with the Eezibleed soon.
Once on my car (was an initial test routine that GAP were working on at the time, so not perfected) - and it was very good - I had replaced the servo and master cylinder so was "empty" - took a couple of rounds the car to get it done.
2nd time on Bodsy's car after we had done the same thing but with a later firmware update on the IID. Again, worked a treat and seemed to be very efficient at getting the air out.Mark.

So what does it do. How does it work?
It applies pressure/brakes? And you open the nipples?

It will when others won't,
It goes where others don't.

Normal brake bleeding is achieved without the need for IID assistance. If, on the other hand, you wanted to do a full brake fluid change then you'd need the IID. Normal brake bleeding methods cannot actuate the valves in the ABS module and it's therefore necessary to use T4 or IID to do that and clear all the old fluid from the system and replace it with new.
Most people don't worry about the small amount of old fluid in the ABS module when doing a fluid change, after all there's not a lot in there and it gradually mixes with the new stuff put in through normal bleeding procedures. It just depends on how picky you are about wanting to flush out all the old fluid.

I had a near catastrophic situation with the ABS on my BMW motorbike and would recommend doing a full fluid change including the modulator . Normal brakes split front and rear , not combined. Front brake lever worked firmly and excellent braking . I had previously changed the fluid when replacing the brake pads, with clear fresh fluid flushed all through. When I was selling the bike a potential purchaser asked if the ABS actually worked. Although all the start up light check had always gone through without a fault. I had never invoked it on the road. I went out and tried it, braked hard and as soon as ABS operated, lever came straight back to the bars and braking effort dropped to virtually nothing. I re-bled the brake and it was full of dirty fluid and air. I cleared it out, invoked the ABS again , two or three times and re-bled until all clear fluid, and the brakes were again solid both with or without ABS invoked. I believe over 12 years the main fluid had been changed but not in the modulator .
It applies pressure/brakes? And you open the nipples?
Still need two people (IMHO)
The Tool tells you what to do - essentially it locks off all outgoing circuits except the one you are working on - starting from furthest from the master cylinder - your pair of hands opens the bleed nipple and then you pump the brakes - the ABS module will then operate at the same time to drive the fluid through - it will tell you when its finished and to go to which wheel next.
Engine running - I can't remember but probably.Mark.
