2nd Gen Non-Engine/Transmission Brake Bleeding for ABS...

[jcbrown]

What is the procedure for bleeding the ABS system. I assume you need to activate the ABS system electrically while bleeding?



Installed stainless steel Speed Bleeders. Works like a charm.

I just flushed my brake fluid on Saturday. I bled all 4 corners the usual way - no special tricks. I have ABS in the rear only. The brakes work fine since I did it.

Ditto, I just flushed mine last week, and have 4 wheel ABS disks, typical way, no problems, they work great.

ABS Bleeding...

Of course you can bleed the brakes like normal. But you'll never get the fluid changed in the ABS circuits. How do you cycle the ABS system and bleed? That is the question?



On the Ford trucks, you can use the DRB scan tool to cycle the ABS circuits.

I believe some shops have a machine that pumps the new fluid in. Can't remember what it is called.

There is a procedure to bleed the Hydraulic Control Unit (HCU) if air enters it. You need the DRB to actuate the HCU's pump and isolation and dump solenoids.



Basically it works like this;



1. Bleed the brake system normally.

2. Do the HCU bleed procedure with the scan tool.

3. Rebleed the brakes to remove any air that was released.



If you're just flushing the system and not letting any air enter, I wouldn't get too concerned. In my opinion, flush/bleed all four corners until clear and then go do some ABS stops to circulate the fluid that was left in the HCU. Maybe do a little more bleeding if you want all the old fluid removed.
