On other cars we do bleeding from calipers by two men method where one person will press brake pedal and open the bleeder bolt on caliper to bleed out old fluid , can’t we do same here ?

You could, if you can do that properly. I've seen people do it wrong, but I never have 2 people so I do it with a power bleeder now

720ss are coming out of warranty. You should get one and show us how to work on them.

What if I told you I'm doing an oil change video on one next week? Well, a 765LT, but same procedure. It's cheaper to do videos on customer cars than buying one!

Not the best way (like you said), but works in a pinch. Most people never change their brake fluid in the first place.

That's a quite neglected service item because people just don't think about it, and it's a major safety thing!

the real problem is the fluid in the calipers. the moisture works its way throughout all the fluid, but when it boils into brake failure at the track, it's the old fluid at the calipers that boiled, regardless of how fresh the stuff in the reservoir is.

It ultimately mixes during use, that's why you're doing it multiple times. You can tell it mixes because of the fluid color change after driving. It's not a flush using this method, it's an exchange.

Any reason not to use ye olde Motive style pressure bleed method? Obviously this doesn't get the fluid bled from the abs hydraulic block (which I'm assuming is what the MDS tool actuated during the bleeding cycle), but should be a complete line flush.

I haven't tried it, but as you noted it wouldn't be complete that way. This method is just super easy and don't need special tools or a second person so I thought I'd put it out there.

@@McMedics Awesome, thx. Been looking at the 675LT and do all my own work so trying to establish the gotchas from a maintenance perspective. Cheers!

just keep pumping the brakes? to mix it all, also, brown doesnt mean its bad, needs to be tested with a tester to confirm.
