Ecoboost rear brake pads - piston compression tool

[Big Kahuna]

Hi Guys,

Hitting 80,000 and getting ready to do rotors and pads for the first time.

Read a bunch of the threads on brake jobs and I've done a ton in the past but was reading the service manual and it says the following on the rear brakes -

Installation
1. NOTICE: Do not use a C-clamp to compress the brake caliper piston or damage to the parking
brake actuator motor may occur.
NOTICE: Do not manually retract the piston or damage to the parking brake actuator may
occur.
NOTICE: Make sure that the brake hose is not twisted when installing the brake caliper or
damage to the brake flexible hose may occur.
NOTICE: Use care when pushing the caliper piston into the caliper piston bores or damage to
components may occur.
Compress the brake caliper piston until the piston bottoms out in the brake caliper bore.

Now on the front it actually says use an old brake pad and compress - the same way I've always done with my old school compression tool.

7. NOTICE: Protect the caliper pistons and boots when pushing the caliper piston into the caliper
piston bores or damage to components may occur.
Use a C-clamp and a worn brake pad to compress the disc brake caliper pistons into the brake caliper
bore.


For the rear brakes they actually show a tool I've never seen before so wondering what people have used? It says to just compress it but it says not to use a C clamp which I assume is so you don't damage the electronic motor on the back. Can I still use my standard old school tool?

Some people showed using a tool that rotates the piston into place but the service manual doesn't tell you to do that so wondering if that actually is the correct method?

Any thoughts? I'm really interested who makes this tool?

looks like a kid's toy. i'm barely a shade tree mechanic but i replaced rear pads on either my Toyota or Honda, i forget, some years ago and discovered the piston needed to be rotated as it was pushed. i didn't need any special tool.

There are dozens of videos on Youtube showing how to reset the rear caliper without a "scan tool" or putting the vehicle in "brake service" mode...head on over there and let us know which one worked best for you.

Did you ever get around to tackling this? I’m at a point where I need to change my rear pads. Curious if you need a special tool or. Or to rotate caliper piston.

For rear brakes you need a tool to rotate the piston back into the cylinder. They now have one that fits almost all cars/trucks and you only need a ratchet. Super easy. brake cube tool is what is is called and just about everyone sells them now. Just be sure to the parcking brake into maintenance mode or it could lose the actual brake "pad location" when applying the parking brake.

Follow this procedure exactly if you don't want to take a chance on manually activating or deactivating the electronic parking brake. It is from the Ford Maverick service manual you got the picture of the tool that they want you to use to turn back in the piston in the rear caliper.

It's the same as our not so old tool that pushes against the outside arms to push the piston in.
True rotate isn't part of the equation they spell out on either front or back brakes.
That was for the auto-adjusting aspect of disk parking brake. Which this is, but the motor for the EPB takes care of that adjustment.

Disabling EBB (hybrids and certain EB's with options that need auto-brakes) just prevents an accidental call for brakes. Key outta the ignition obviously, don't open door like getting ready to drive while fingers in the wrong place.
But back has to have that EPB released - and the instructions given above don't work on a production run of trucks.
Can't recall if TSB gives new instructions, or just wishes the tech good luck with that...

Before you start turning wrenches on a 2024 Ford Maverick, there is one critical thing to know: it uses an Electronic Parking Brake (EPB).

Because the parking brake is electronic, you cannot simply "disable" it or force the piston back with a C-clamp like an older truck. If you try, you risk damaging the expensive internal motor. You need to put the truck into Brake Maintenance Mode.

You say the instructions for brake maintenance mode "don't work on a production run of trucks." What exactly is a production run of trucks? I assume you mean a "batch" of trucks. If so, who falls into that group?

It was an early batch.
When the given process doesn't work.
When using Forscan Lite and the process doesn't work.
Then in that group, never seen a defined range given.

Unplug EPB mechanism from control cable, and use 9V battery instead to retract.
Several videos on using that method. Actually on many vehicles, that don't have a driver initiated maintenance mode like the Mav does.

Still run thru process though, because it should still put the EBB into maintenance mode so it's not firing off accidentally, just will not retract the EPB.
