I've got a '94 Legacy with the Nippon ABS-2E system. What's the right brake bleeding order for this setup?

 

In an Endwrench article, it says:

Air Bleeding Overview

The air bleeding procedure for the ABS-2E system is similar to that used for other systems, with a few added steps

....

Then bleed the secondary chamber of the master cylinder first and the primary

chamber second. To accomplish this, work in the following order:

1. Right front brake 3. Left rear brake

2. Left front brake 4. Right rear brake

 

I think that makes sense since this ABS has a combined channel for the the rear brakes. But it's a different order than I've seen in other Subaru publications, which is:

 

1. Right front brake 2. Left rear brake

3. Left front brake 4. Right rear brake

 

Which should I use? Maybe I"m overthinking it and it doesn't really matter. There is no air in the system that I can tell; I just want to change out the fluid.

Use this one

 

1. Right front brake 2. Left rear brake

3. Left front brake 4. Right rear brake

i went through a similar process bleeding ABS for the first time...turns out i haven't had any issues just plain on bleeding the things.

Thanks for the help. I went through and bleed everything once, then put the ABS through sequence control a couple times, and bled again, it seems to be good.

i've never done the control sequence thing, so you should be golden. thanks for reporting back and glad it worked out.

I just like the sequence control because I think it helps get out old fluid that might be in the unit.

 

No!!!!!!!!!!! Ok it didn't work out perfectly after all. It wasn't related to the bleeding, but I spotted a brake fluid leak coming from above the tank in the rear. I had this happen on my '96 so I"m replacing both rear line sections from underneath the seat to the brake hoses.

 

This vehicle has been down for over a year. I finally got back at it and finished up the timing belt, struts and springs, and a bunch of other stuff. Then the battery went bad. Now I was just putting it down off the jack stands and I swear it just started leaking right then!!!!!!!!! argh..... oh well hopefully it won't take too long.
