Default Bleeding Cosworth ABS system

The system needs to be bled on mine and need to know the correct sequence.

I'll be using an eezibleed so have that side of things sorted but what i need to know is what corner do you start and finish with??

I thought it was this but i may be wrong:

LR, RR, LF, RF

Also what the deal is with the ABS pump - plugged or unplugged - do you need to let the pump prime for the rears only.

As much correct info as poss please

There's a few different ways of doing it, I do mine by disconnecting the abs pump MOTOR by pulling the connector then start nearest the pump working next nearest etc, with ignition in "accessory" position 1, this ensures the abs valve block has opened.

When you talk about the pump motor are you talking about whats on the drivers side with res bottle on or the block on the passenger side? and which connector

And can you show the formation i should go

bleed rears by putting the ign on as said and just open the bleed nipple and just touch the foot brake slightly fluid will come out of the nipple once air stopps bubbling out tighten up the nipple
do the same on the other rear one
then turn off the ign
and bleed the fronts conventionally

ie open nipple push brake down fully then tighten nipple release pedal and repeat this till air stops
then finish with the one closest to the master cylinder and repeat process as on the other front one

any probs give me a call

Shouldn't feel springy at all, I mean the actual pump motor on the drivers side, underneath the reservoir bottle area facing front.

Loosen the centre pipe on abs block if you have air trapped in it.
