Vacuum bleeder is much easier:

I'm anxiously waiting to learn of a better method that people are using to bleed their brakes on these electronic brake boosters. I had just found a nice pneumatic tool for bleeding brakes just a couple of years ago but now all three vehicles in my garage have electronic brake boosters. I used to use a Motiv brake bleeder that I would have to attach to the brake fluid reservoir and then add a pressure to it, but I never liked doing it that way. Very curious what the dealers and other pros at shops are using.
the pros use the motive

that’s much better. I thought you’re account got hacked lol.
I had one of those and personally I had a really hard time with it. You really prefer that over the motive?

I don't know the motive, but that vacuum bleeder has made bleeding very easy for me. I've been too afraid of applying positive pressure to the reservoir because of the potential mess. Found that Capri system several years ago and haven't looked back. Just an alternative for those who want to try it.

Looking at the format of the first link, it does look sketchy, ha!

yeah I mean I clicked it but it takes me here:
If it works well for you then that’s the best tool!
I struggled with it and switched to the motive and I’ve had no issues and bleeding done in 20 minutes

The Motive is the way to go, for a layer of safety wrap a blanket or shop rag around the reservoir and cap. Check to ensure no leaks first. We use between 10-18 PSI.
I cycle the brake pedal about 6 pumps per bleeder with the Motive hooked up. This helps move more fluid through and ensures a firm pedal.
SRF is the way to go if you're tracking a good amount.

Might be a bit off topic but can I use Motul 5.1? Says it is non silicone so I think I am safe as far as that goes.
Also, how will I know if I have bled out all the original fluid?
I autocross and even though all is good right now I think I should be proactive and upgrade the fluid.
Thanks for your help.

I'm a X-Road Racer who is **** about having fresh fluid to start each race weekend and for starting each day with fresh fluid in the Calipers. From what Is read you don't really purge all the old fluid out this way.

srf, vp
when talking about srf there is a dot4 version and a dot5 (silicone) version. make sure you use dot4. I run the vp brake fluid and have no problems. I bleed the fluid out of the calipers and cycle some fresh fluid in after 2 track days. To avoid needing two people to bleed the brakes i use speed breeders. www.speedbleeders.com
they are excellent and you can bleed your brakes the old fashioned way without a second person.
vacuum bleeders are not recommended to use on the c8, and the pressure bleeders have trouble with the cap sealing on the plastic tank. also if you aren't familiar with pressure breeders its easy to have a brake fluid mess quickly and ruin your paint. Just my 2 cents worth, but what do i know after bleeding brakes on my circle track cars for 20 years
