Default Order of air bleeding?

Hi -

I've got a 2001 Outback, and I'm wondering: is there a specific order in which you bleed the brakes? Thanks in advance!

I think it has ABS Brakes?

The order is closest wheel to ABS unit first. From the 2000+ FSM:

Brake fluid replacement sequence; (A) Front
right → (B) Rear left → (C) Front left → (D) Rear
right

What I just found in the service manual agrees with your reply. Thank you!

Anybody know if there are special issues with the process of bleeding brakes on a car with ABS? Anything extra that needs to be done?

Yes. You should run "sequence control" on the ABS system to remove any air from the ABS hydraulic unit.

You can run sequence control by grounding two contacts in the diagnostic connector in the driver's footwell, turning the ignition switch on, and holding the brake pedal down immediately after the abs light goes out.

Consult your service manual for complete details on the connector and sequence.

Thanks so much for the information! When in the brake bleeding process should I run the sequence control? Also, any idea where in the service manual this info is? I have .pdf files of the manual, and they are in no particular order...

The manual says 4-4 (W15DO) for the perform sequence control, however I can't find that particular W15DO in the manual...

Ok, here's a dumb question.. how do you know when "sequence control" is done? I jumpered 3 and 6 on the diagnostic connector and pressed the brake pedal within .5 seconds of the ABS light going out, then what? The manual simply says, "After completion of ABS sequence control, turn ignition switch OFF." I sat there with the brake pedal down for about 30 seconds watching, listening, and waiting, nothing seemed to happen?

This would be such a pain in the butt to follow (if u were using jack stands at home really). Ideally in my Hondas I do the rears first followed by the fronts.

Did you jumper them together only ? They both should be grounded (and you relly need to mash on the pedal - the pressure you're creating is supposed to do the work. you'll feel it in process.
