I'm about to replace the ABS pump on my 2015 Ford Grand C-max. A fiddly job, but I'm giving it a try. Motvated by potentially saving ~£2500.
I'm asking you about bleeding: Normally you're bleeding by pumping, but I'm thinking - since all air is in the ABS unit - would it be a good idea to force bleed from each wheel? The ABS unit is very close to the master/reservoir. I've got a large syringe to push fluid from the blleder nipples.
Any thoughts or experience, anyone?

I blank/block the pipes from the master cylinder when I remove the ABS units. Normally turns into a right ball ache if you get air into the master cylinder. After replacing bleed in the normal way. Keep the battery out on the Cmax so you can check for leaks with someone holding the pedal down.

Thank you, nice to have input from someone knowing this model! I'll try to blank them, got a set of little silicone plugs for this purpose. The problem is the placement - I guess using two hands is not possible...
We'll see😎

Yes done a couple of Cmaxs. Once that battery and case are out of the way it's not so bad. Thing I took the lower screen panel out too.

I should also mention keep dirt out when take out and reassembling. Are you having your unit remanufactured?

 

Take your time like I never do and you'll fine. ​

No, I bought a used one, planning to swap the control unit to avoid need to reprogram. 99% sure it's a sticking valve. Thanks for good advice! I was thinking of removing the cover, but a) it could seem like it was sealed against the windshield, and b) it seemed like quite a disassembly job , like wipers off.
One more thing: I'm afraid of fucking up the nipples, thinking of heating the aluminum lump and use cooling spray on nipøles, a good idea?

Yeah, I'm telling myself I've done harder stuff😎

Wipers come off with a wiggle and never had a prob with the plastic panels, all slots together. Try whatever you've had best results with for the nipples. Fronts are normally ok apart from corrosion, should be 9mm, rears into the alloy body will be trouble if you're not a regular fluid changer so heat and freeze and let us know how that goes. Single hex spanners or sockets are your friend.

Right to the point   - Thanks again!
