Im a chevy guy so I have no clue what im doing here.

My brother came to my house to do a full brake pad replacement on his 2021 f150 stx. ive done over 5 brake jobs at this point and was very, very confident in this job. Unknown to me, the rear calipers are equipped with the Electronic Parking Brake systems, which were very new to me. Ended up needing to replace a caliper, and now we need to bleed the brake system, which appears to be very unlike what ive normally done. Stuff like needing a computer to initiate a auto bleed system, and the use of a pressure bleeder? Again, very unfamiliar.

numerous searches online only being me to brake bleeds for pre 21 year f150s, which follow the basic procedures that im familiar with. Could someone here please help me with figuring out how to get these brakes bled? The truck is already in brake service mode.

Im crunched for time. Were 20 minutes from the closest mechanic shop, and my brother needs this truck to get to his emt jobs.

Thank you

 

I know some have to be put in "Maintenance mode" but I have no experience with it, hopefully others will chime in.

 

Yeah, when we took the caliper off, the brakes weren't in brake service mode yet. After putting it in the service mode, the caliper piston shot out and chipped on the pavement. New tech sucks, but im sure someone here knows how to help. Thank you!

 

Update on issue. Truck is being sent to a shop. Im not about to shell out a pretty dollar for all the hardware and programs.

 

For future reference, just bleed the brakes like normal. Then drive the truck for a while (like a month) and do it again. The reason for using a computer is to also replace the fluid in the anti-lock brake module. I'm not sure how much fluid the module holds but I figure driving for a while allows the old fluid to mix with the new, then flushing again further dilutes the old fluid. Similar to doing a pan drop and refill on a transmission. And at any rate, you'll already be miles ahead of the 95% of people who never flush brake fluid.
