Mityvac brake bleeding: Closest wheel first?

[Mustang_Cougar]

I know that it's standard to bleed the passenger rear wheel first, but the instructions that came w/my Mityvac advise to start w/the driver front. Does that sound kosher? This is a complete brake job (M/C-to-drums) and I've already bench bled the M/C. But Mityvac's suggestion caught me off guard; ignore that or is there a specific reasoning (ie, vacuum draw as opposed to brake pump)?

Thanks.

Nope, farthest first

Depends on the car honestly. My Volvo the proper procedure is to start at the drivers front and work the way around opposite of what you would think is normal.

with the vac pump and dual brake system, it really doesn't make much difference which end you start at...

Have your brakes been circumcised?

Less waste.

Farthest first, closest last, is typical. A common brake flush sequence would be (first to last) passenger rear, driver rear, passenger front, driver front. I successfully used that sequence with a Mityvac many times back in the day. If you're living in Britain or Australia with a right-hand drive car, or anywhere south of the Equator, flip the car upside-down before flushing and use a reversed sequence.

Ouch! Sounds painful.

Usually it depends on if the brakes are front/rear split or diagonally split (common with FWD). With diagonally split, instead of RR, LR, RF, LF the order is usually RR, LF, LR, RF, but I'm not sure it really makes much difference.

I tried farthest first, closest last on 1 car and closest first, farthest last on another car with Mityvac 7201 and found that there is no difference.

I've always done farthest first, but I guess it shouldn't matter as long as you are pulling fresh fluid through every endpoint. Unless there are some configurations that are likely to allow air bubbles to run back up into the lines if done in the wrong order.

I have heard and used the Mantra of bleeding the farthest first.
I now don't know why this is recommended.
It is a closed hydraulic system.
It wont matter where you bleed first, UNLESS it is an ABS system with special needs.

I agree.

Ok.
WHY the farthest?
I'm not being a doo doo head, but I can't think of a good reason, except we have been told this umpteen jillion times.
[like I said, ABS systems should follow the letter of the law for their bleeding sequences.]
