Brake job without going into brake maintenance mode

[LC48]

My assumptions on how the system works based on the below TM excerpts:
1. Switch tells ECU Park brake is commanded
2. ECU checks permissive list, if all good it sends command to the actuators
3. Actuators turn driving piston inward to a pre-set torque limit. Current draw monitored by ECU watching for faults.
4. When commanded off the actuator reverses a few turns past zero torque, this way it is ready to go for the next command. Over ti e as the pads wear the piston winds up sitting proud of the bore just like the normal brake pistons do - hence the need for service mode.
5. Service mode would drive the actuators in reverse until torque limit is hit, placing the piston within its bore.

Thoughts?

If you drive gently in a hybrid, or mostly highway travel in a hybrid, we're probably not going to need this for 200k miles. I'll probably trade it in before mine needs new pads.

Wow, so smart.......

So, in a nutshell, service mode simply retracts the pistons all the way and most likely prevents any input like hitting the brake or park brake switch from doing anything?
I've done rear brakes on a Lexus with elect park brakes and the way to do it is remove the actuator and turn the pin to retract the pistons. This is because an exspensive scan tool is needed to retract the pistons.

I believe you are on it @Silver23 , seems the most logical to me with the information we have.

Maybe in Cali. Unfortunately, in the rust belt, brakes need to be serviced regularly, worn or not.

So I was able to replace my rear brake pads without going into brake maintenance/service mode on my 2022 ford maverick. This is what I did.

Tools

- 7mm hex bit
- brake compression tool: DASBET 22pcs Universal Disc Brake Caliper Piston Compressor Wind Back Repair Tool Kit for Cars https://a.co/d/2KODOK0
- laptop with forscan and compatible OBD2 adapter .
- flat head screwdriver
- caliper hanger (I use old metal coat hanger)
- new pads/rotors ( I got raybestos pads off of rock auto.

1. Make sure parking brake is off

2. Open hood and remove brake reservoir cap. Put cap in safe spot.

3. Put brick/rock behind front tires so truck does not role

4. Loosen lug nuts on rear rims.

5. Jack up truck on one side, remove lug nuts 21mm and remove tire/rim. Place under truck for added safety

6. Remove dust caps to get at slider pins. (Put in safe place)

7. Unplug electric parking brake wire harness. Might have to spray wd40 and use flat head screwdriver to release harness. (Note: this step is critical)

8. Remove brake retainer spring. Use flat head screwdriver driver. Should just pop off. Keep in safe place. If you did mangle it. The replacement pads should have replacements.


9. Use 7mm hex bit and remove brake slider pins. ( Keep in safe place.)

10. Grab brake piston compression tool kit and use adapter #7 ( if you got the same kit I did). Follow this video on how to compress your caliper:

11. After compressing caliper hang it up using caliper hanger or coat hanger

11.5 remove pads and brake caliper bracket if you are replacing rotors

11.6 remove and install new rotor

11.7 re-install brake caliper bracket

12. install new pads ones (clean and grease pad contact areas )

13. Grease slider pins and re- install piston
note: might have to compress piston more if you can't get it to fit.
Note: I added blue lock tight on sider pins for added security.

See video for procedure:

14. Reconnect electric parking brake wire harness and remove caliper hanger

15. Re- install slider pin dust caps.

16. Re - install rim with 21mm lug nuts

17. Lower jack and torque lug nuts (I go 90 foot pounds)

18. Follow steps - 1 to 17 for other side.

19. Boot up laptop with forscan and connect to truck. (Truck has to be in acc mode).

20. Clear any abs obd2 codes.

21. Go to service procedures and run "apply and release calibration". Might get error on dash, just ignore.

22. Disconnect forscan and obd2 adapter and shut down truck.

23. Remove bricks preventing truck from running away.

24. Re install brake reservoir cap and close hood.

25. Pump brakes 3 time. Start truck and go for a short drive.

26. When back, park truck and engage parking brake then release. Should have no errors!

**Note: I take no responsibility for any damages. This procedure worked for me.

Why bypass the service mode?

Why bypass the service mode?

There is a bug with 2021-2022 Ford escapes, bronco sports and mavericks are unable to go into brake service mode unless you use Ford's frds software.

I did not know this its weird i work on one friday ford bronco and had no problems doing them following the normal procedure i posted above.

Was it a bronco or bronco sport?

Bronco sport

Still here. On the shop working on it as you can see i did the rear brakes.

Is that a 1.5 or a 2.0?

I have tried every combination mentioned in all the forms, trying to get it into maintenance mode to the point I drained the battery for over a month with no success (posted this in other threads).

I am up in Canada so labor is very expensive (500 - 700$ for a rear brake job at dealer). I am also a former jeep wrangler owner and have the skills and tools.

Did the research and decided to take the chance.

I have doing brake work for years when needed. I can do what was described by the poster with the mechanical work.

I do have a laptop. Do I need to complete the technical computer usage as poster described?

What does the technical usage telling the truck's computer anyway?

thank you for the information and pictures. I was hoping information would be brought up soon, not because I need pads. Infact just got the truck 5 days ago.

I can do the mechanical work you described. But didn't know a computer was needed.
Is that a necessity. What do I need other then the laptop?

I don't know what forscan is. What do I need other then the laptop to do what you did?
I have an obd 11 and my phone i installed called Torque to communicate to the obd 11.
