Playing with my new AE. Noticed that AE has something that says "Bleed, Bleed LF, Bleed LF, Bleed Prime, Bleed Release, Bleed RF, Bleed RR". I assume that thes activations under Tire Size Configuration on the Test Onboard System tab, is for bleeding the ABS brakes. Am I correct?

 

I found this answer on another diesel forum. it was posted by a Ford Diesel Tech.

The "service bleed " is a procedure used when there is the possibility that air has entered the Hydraulic Control Unit (particularly the accumulator chamber).

To perform a "service bleed", one would bleed the brakes normally first to remove all air from the lines. Then, one would enter the serviuce bleed procedure... the scan tool will command the ABS pump to run and cycle the isolation and dump valves to remove air from the accumulator. The brakes are once again bled normally...


I use a Motive Power Bleeder to replace my brake fluid. Perhaps you need to activate the ABS pump to remove any air from the accumulator, but that doesn't happen during normal fluid replacement.

Read this from StopTech Brakes: StopTech : Balanced Brake Upgrades

After I bleed with new brake fluid, i take my truck or car to an empty parking lot and get on the ABS a few times, then bleed again. If ABS activation does get old fluid dumped into the brake system, maybe that helps. Couldn't hurt.

 

Well in the activation window of my AE it has an option to click to activate the list of brake line bleeds.
Just lick to activate. Just wandering what is was for.
After 5 years of us. I figured that a brake bleed was in order.
If it doesn't I just make plans to manually bleed my brakes.

 

That makes sense. Thanks

 

I edited my original post. Check the StopTech link. As I wrote, I bleed conventionally, then get on the ABS several times and bleed again. that's what StopTech recommends if you don't have the factory tool.

 

Good idea. LOL
