Easy Brake Bleed with FORScan

Has anyone tried this? I just ordered new pads and rotors from R1 concepts and I was looking at adapters for my motive power bleeder when I came across this video. Seems like an easy, no-brainer solution which I'm going to try.

ABS units though do need to be bled, so this helps take care of that.

Don't forget to use a plunger to suck all the old crappy fluid out of the reservoir, and then replace it with the nice new fluid before starting.

I don't think this procedure moves enough fluid to 'flush' the system if you are converting to a nice new high temp fluid. Might have to repeat the ABS bleed twice, or choose a different setting that maybe actuates the unit for longer.

The video seems like it moves enough fluid but good point. I have a dedicated turkey baster for that!

I'd rather use the Motive bleeder since it works so well and you can bleed the clutch with it.
Do you know which adapter is for the RS?

When you do it with Forscan you have different options for the type of bleed. When I do it I always select master cylinder or ABS module replacement bleed rather than brake hose. That way Forscan pumps the system longer, if you choose a different bleed, you’ll notice a time difference. The longer bleed allows more fluid to be pushed through the system making a full flush completed in less time than other methods, as long as you refill the reservoir. I make it a point to bleed all of my ABS vehicles using this method through either Forscan or a two way ABS equipped scan tool.

Yeah, the Forscan way of bleeding is definitely worth trying.
But what makes me sad is the way the information is being transmitted nowadays. The same piece of useful information in text form takes a minute to read and to understand. Instead of this - the youtube video takes 12 minutes of my life for no reason... WTF?
I didn't mind this too much as it just showed you step by step for each wheel. Plus this paticular dude does a lot of great work on sync stuff.

It's better than your typical video where it's LIKE, SUBSCRIBE, HIT THE NOTIFICATION, 5 minutes of sponsered content, 5 minutes of personal trash, then 2 minutes of the actual content.

Like my guy I'm just trying to see how to do this like the CJ pony parts videos.

Why the hell would you want to go through this crap when you can do it faster and easier with a $75 brake pressure bleeder. Hook it up to the reservoir pump it up to 15-20 psi and go around to each calliper and open the valve for 30 seconds...done. I understand that this FORSscan process flushed the tiny amount of fluid from the anti skid control valve assembly but honestly one hard braking event that initiates the anti lock will do this if it concerns you.
It just seems like the "geek" way to bleed brakes. Interesting but ultimately pointlessly complicated.
Reminds me of the new scales at my Gym. Gone are the old simple fast "stand on this device and it displays you current weight" and replaced by the all singing dancing take your shoes and socks off body mass calculator and weighing contraption. Now simply weighing yourself takes 30 seconds of selections and calibration just to simply weigh yourself, if you can actually get on the thing for people doing all the other stuff on it. Sometime you can make the simple stuff overly complicated. This bleeding process does that.

Just wanted to follow up on this.

I bled the brakes last night using Forscan and it went better than I expected. It's pretty convenient to just hook up a bleeder bottle, crack open the line, and then push a button to watch it go. If this could be done via bluetooth then it would be perfect. The only downside is that for a full fluid replacement it does take a few times but I also didn't test any of the other options than brake hose replacement.

Bonus is that with the car on it warns you when the brake fluid is low so you can top up if you didn't put enough originally.

Also the pedal has never felt better though I'm not sure if thats due to a combination of new rotors, pads, and fluid.

You can, you just need a BT OBD2 adapter that can talk to Forscan. I have the OBDLink MX+ and when I had Forscan I could do everything with it wirelessly via the laptop.

Not sure the range though, I never tried it outside the car. Mileage may vary, quite literally.

@Zaluss
To be clear, when you say it takes a few times to fully bleed, are you saying you bleed all wheels a few times or bleed the same wheel a few times?

Thanks,
I bled RR a few times to get as much of the original fluid out as possible and then bled RL, FR, and FL once.

Brembo's obviously get bled twice, inner then outter.
