2020 Brake Fluid Flush
I think this is my first post. I want to perform the brake fluid flush maintenance on my 2020 Super Duty. I'm interested in doing this myself. I've done a search on this forum and came up empty on anything regarding tips/do's/don't on this subject. Any advice out there?
Thanks, Andrew

As already stated, a pressure bleeder makes things a breeze.
Notes I made when I did mine.
1. Start at the wheel farthest from the master cylinder.
2. Make sure you have enough brake fluid. I was surprised at just how much it required.
3. Get a piece of rubber brake hose to go over the bleed fitting and run that hose into a container in order to catch the old fluid.
4. I was able to tell when the new fluid had flushed through.
Good luck.

I bought a cheap($220) electric pressure bleeder going to do a car I'm selling this weekend, then my truck soon after.
I recommend getting a cheap scan tool like the OBDLink MX+ since it works with forscan too, (but any tool with bidirectional controls should be able to do it just check or make sure about the return policy)to put the ABS in service mode to flush the fluid in it too, it is an often overlooked part of the job by DIYer's. And both are handy tools to have, being able to easily bleed a brake system solo is very freeing and takes all the frustration out of the job, well if your bleeders aren't plugged solid or twist/round off.

I need to do mine in the spring. I have a vacuum bleeder so it will be a quick job.

I have one of these for the dot 4 trucks and 1 for the dot 3 trucks.. Makes quick work of the flush process.. I suck out the master first. Then add fresh fluid then hook this up and flush it... The DOT 4 use a a screw on adaptor. The Dot 3 use a 3 tab adaptor.

And be sure to use the right brake fluid. My ‘19 uses DOT4 LV and I imagine your ‘20 is the same. The LV part is particularly important if you operate in a cold weather area.
This is the fluid I used along with a Speedibleed bleeder
Pentosin 1224116 DOT 4 LV Low...

As long as the brake bleeder hose is submerged in fluid, you can do the job yourself.
Putting the abs in service mode is overkill on a nice 2020. If you need that, and a pressure bleeder, just pay a mechanic to do it.

True. I didn’t put my ABS in service mode for the brake flush even though I had a Autel scan tool in the console.

I have had good luck with both of these kits on this truck and various others:
https://www.harborfreight.com/pneuma...kit-57057.html
https://www.harborfreight.com/brake-...der-92924.html
The pricier kit holds up a lot better than the cheaper one but both work, makes it a pretty quick job.

I just flushed the brake fluid on my 2020 a couple of weeks ago. It was a simple process with one of these https://www.harborfreight.com/pneuma...kit-57057.html as mentioned above. I agree with all that has been said here but you don’t need to put the ABS in service mode. First suck the old fluid out of the reservoir. I didn’t figure out how to get the front of the reservoir fluid out. There wasn’t any access with the hose. It's not much fluid and I figured when I flushed the fluid through it would empty on its own. You will need 2 of the bigger bottles of brake fluid. One bottle only filled the reservoir after I pumped out the old fluid.

Thanks to all who replied. I found out a friend of mine has a pressure bleeder I can have. Its a Motive brand and it is new, never used as Amazon sent him the wrong one and Amazon told him to keep it and they would ship the correct bleeder. It happens to be the model for ford. There are YouTube video's on bleeding brakes. I'm going to get this done in the next couple weeks.
