REPLACING REAR PADS ON ST

[Silver spruce ST]

Do have to reprogram the computer when replacing the rear pads due to ABS and the electronic emergency brake?

i believe you need to put the electric parking brake in maintenance mode and exit when you are done. use forscan.

I don't have a forscan

You don’t need Forscan for service mode. Just Google it…it’s the same for all new Fords. You’ll find the sequence online.

This is the procedure if you don't have a capable scantool:
NOTE: Brake service mode is also known as brake maintenance mode.

NOTE: Prior to carrying out the brake service mode activation steps below, clear all EPB and EBB related DTC's.

NOTE: Carry out the following service mode activation procedure to deactivate the EPB and EBB systems. The EPB and EBB system can also be deactivated using the diagnostic scan tool and following the on-screen instructions.

NOTE: This mode is required to deactivate the brake boost and to allow the entire brake system to be bleed manually.

NOTE: This mode will cause all the associated brake warning indicators and text messages to appear.

1. Set the ignition to ON.

1. Release the EPB.

1. Press and hold the accelerator pedal and place the EPB switch to the RELEASE (downward) position. Continue to hold the accelerator pedal and EPB switch.

1. Set the ignition to OFF then set the ignition to ON within 5 seconds. Continue to hold the accelerator pedal and the EPB switch.

1. Set the ignition to OFF then release the accelerator pedal and EPB switch.
   
   • NOTE: The brake system will be deactivated, preventing brake application until service has been completed and service mode has been deactivated. The yellow EPB indicator will be illuminated and Maintenance Mode will display on the message center.
2. • NOTE: When replacing brake pads in service mode, the brake caliper piston must be compressed into the caliper housing. The brake caliper piston does not have to be rotated while compressing the piston.

Deactivation

NOTICE: The brake system performance will be significantly reduced when the brake system is put in service mode.

NOTE: Carry out the following Brake Maintenance Mode deactivation procedure to activate the EBB and EPB systems. These systems can also be activated using the diagnostic scan tool and following the on-screen instructions.

1. Set the ignition to ON.

1. Press and hold the accelerator pedal.

1. Place the EPB switch in the APPLY (upward) position. Continue to hold the accelerator pedal and the EPB switch.

1. Firmly press the brake pedal for at least 1 second. Release the brake pedal while continuing to hold the accelerator pedal and the EPB switch.

1. Set the ignition to OFF then set the ignition to ON within 5 seconds, then release the accelerator pedal and the EPB switch.
   
   • NOTE: Once the ignition is set to ON, the EPB system will immediately apply and release the parking brake to guarantee sufficient air gap between the rear brake pads and brake disc. If the EPB switch is not released prior to completion of this sequence, it will apply the EPB. The EPB will have to released prior to moving the vehicle.
2. • NOTE: When Brake Maintenance Mode is deactivated, the Yellow Parking Brake and Red Brake Warning Indicators turn off and "Brake Maintenance Mode" no longer displays in the message center.

Please help. What is EPB. I think it's EMERGENCY PARKING BRAKE ? Do I really have to do this?
I can't use the tool to push it in ?

Yes you need to follow this sequence. Brake Service Mode is the only acceptable way to perform any brake work.

There's no emergency. It's a parking brake. Electric Parking Brake.

Only safe way imo. The EPB gradually screws in tighter as the pads wear. The procedure retracts the EPB completely. To change pads safely. Then the rest of the procedure adjusts the screw/piston to the proper length for the new pads. There may even be a calibration during the process so the computer knows where the piston is.

Thanks for the info, guys. Really helpful stuff here.

Stuck in service mode. Any suggestions?

Force it out with Forscan.

 

[LuxST]

Unfortunately I don’t have forscan

update: had air in the brake line. Good to go.

 

[GearHead_1]

You opened the system to replace the pads?

Not exactly. Let’s just say I made a dumb mistake live and learn lol

Please post your mistake so other can learn from it.

The rear piston didn’t retract all the way when putting it back on with new pads. I didn’t open reservoir cap. So I took the cap off. I wanted to try taking it out of service mode then put it back in service mode to see if it would go all the way in with cap off. I went to take it out of service mode and the piston popped out cause of no resistance. It remained in service mode cause of the piston popping out. Got it back in and had to bleed it to get it out of service mode.

Thanks for posting! We’ve all done stupid stuff. I ran the reservoir dry while bleeding the brakes when I was a youngster. I’m a lot smarter now because of all the stupid mistakes I’ve made.
