Brake bleed query

[fortyonerag]

The car (41 SD convert) is new to me and I'm seeing some little weeping at the M/C boot.

Wheel cylinders appear to be in good shape (not weeping) and car stops OK.

I'm fixing to put a kit through the M/C and flush the system. Can I confirm the bleed order?

Right rear wheel, then the left rear, right front and lastly left front.

Anything else I should be doing?

Many thanks

That's the right sequence. (I assume you know to bench bleed the mc). You may want to check the wheel cylinders a little closer. If the mc is bad, the wheel cylinders may be on their way out, even if not leaking

No need to bench bleed a single circuit M/C. Best not to push the pedal all the way to the floor either when bleeding. Might be time to do your lines...

It's an "older resto" (my guess about 15 years back) so I'll decide about the lines when I see what I get from the flush. Rubber looks OK, but we'll see.

Thanks for the advice all!

Talkwrench has this one correct. A single reservoir master does not require bench bleeding.
I would at the very minimum open up the wheel cylinders and inspect them. My guess is you'll find a lot of "gunk" caused by moisture entering the system through the past fifteen years.
If I am correct, you may most likely (simply) clean them out and reassemble.

As a rule of thumb, bleeding starts with the cylinder that is the furthest from the master. Then, move to the next furthest, etc.

I'm curious what is a good rule of thumb as to how often a system should be bled? I use dot 3 and try to bleed the system every 2 - 3 years.

I've never heard a "rule of thumb" for this schedule. I would think it depends largely on where you live (humidity) and thus, how quickly moisture is absorbed in to your hydraulic system.
From my experience here in Wisconsin, the summers being typically very humid, a guy can safely go two to three years prior to any adverse effects showing up.
