Replacing the rear brake pads on a modern Ford Explorer requires more than just a wrench; you must navigate the electronic parking brake system to avoid damaging expensive components. This guide provides the exact steps to put your vehicle into maintenance mode and complete the physical swap safely at home.
Stopping power is the most critical safety feature of your vehicle. When you notice a high-pitched squeal or a grinding sensation from the rear of your SUV, it is time to act. A 2022 ford explorer rear brake pad replacement might seem daunting because of the modern electronics, but it is a manageable task for any DIYer with the right instructions.
In this guide, I will walk you through the specialized “Maintenance Mode” procedure and the physical mechanical steps required. We will ensure your braking system remains reliable whether you are commuting to work or heading out on a family camping trip. By the end of this article, you will have the confidence to handle this job like a professional technician.
We will cover everything from the necessary tools to the specific torque nuances of the Ford chassis. Let’s dive into the details and get your Explorer back into peak stopping condition. This process saves you significant shop labor costs while ensuring the job is done with precision and care.
Understanding the Electronic Parking Brake (EPB) System
The 2022 Ford Explorer utilizes an Electronic Parking Brake (EPB) system rather than a traditional cable-actuated handbrake. This system uses a small electric motor attached to the rear calipers to squeeze the pads against the rotor. You cannot simply use a C-clamp to push the piston back, as doing so can permanently damage the internal motor gears.
Before you even touch a lug nut, you must electronically retract these motors. This is done through a specific sequence of button presses inside the cabin. Entering this mode allows the piston to be pushed back manually without resistance, protecting the sensitive electronic components from mechanical failure.
Failure to use maintenance mode is the most common mistake DIYers make on modern Fords. If you feel heavy resistance when trying to compress the piston, stop immediately. Verify that the dash display confirms “Brake Maintenance Mode” is active before proceeding with any mechanical disassembly.
Tools and Materials Needed for the Job
Having the right tools on hand prevents mid-job frustration. For a 2022 ford explorer rear brake pad replacement, you will need a standard metric socket set and a few specialized items. Ensure your workspace is level and well-lit before you begin lifting the vehicle.
- 21mm Socket: For removing the large lug nuts on the Explorer wheels.
- 13mm Wrench or Socket: For the caliper guide pin bolts.
- Brake Caliper Tool or C-Clamp: To gently compress the piston once in service mode.
- Torque Wrench: Essential for tightening bolts to factory specifications.
- High-Temperature Brake Grease: To lubricate the slide pins and pad contact points.
- Brake Cleaner: To remove shipping oil from new rotors or dust from the assembly.
I also recommend having a wire brush and a small bungee cord handy. The wire brush helps clean the rust off the caliper bracket where the pads sit. The bungee cord is used to hang the caliper so it does not dangle by the rubber brake hose, which can cause internal damage to the line.
Step 1: Entering Brake Maintenance Mode
This is the most critical phase of the 2022 ford explorer rear brake pad replacement. Sit in the driver’s seat and ensure all doors are closed. You do not need a diagnostic scan tool to perform this; Ford built a “cheat code” into the dashboard controls.
- Turn the ignition to the ON position (press the start button without touching the brake pedal).
- Release the parking brake if it is currently engaged.
- Press and hold the accelerator pedal all the way to the floor.
- At the same time, press and hold the Parking Brake Switch down (in the release position).
- Turn the ignition OFF and then back to ON within five seconds, while still holding the pedal and switch.
You will hear the electric motors in the rear hum for a few seconds. A message will appear on the instrument cluster stating “Brake Maintenance Mode.” Once you see this, it is safe to turn the ignition off and begin the mechanical portion of the repair.
2022 ford explorer rear brake pad replacement: The Physical Removal and Install
Now that the electronics are retracted, you can treat this like a traditional brake job. Start by loosening the lug nuts while the tire is still on the ground. Use a floor jack to lift the rear of the vehicle and secure it with jack stands for safety.
Remove the wheel to expose the brake assembly. Locate the two 13mm bolts on the back of the caliper. Once these are removed, gently wiggle the caliper off the rotor. Use your bungee cord to hang the caliper from the rear suspension spring, ensuring there is no tension on the hydraulic line.
Pop the old pads out of the bracket and remove the stainless steel hardware clips. Use your wire brush to clean the surfaces where the clips sit. Apply a thin layer of brake lubricant to the back of the new clips and snap them into place. This prevents the “clicking” noises often heard after a DIY brake job.
Slide the new pads into the bracket. Ensure the friction material is facing the rotor. Now, use your caliper tool to slowly compress the piston. Because you are in maintenance mode, it should slide back with very little effort. Slide the caliper back over the new pads and tighten the 13mm bolts to 20-25 lb-ft.
Inspecting the Rotors and Hardware
While the caliper is off, take a moment to inspect the brake rotor. If you see deep grooves or a “lip” around the outer edge, the rotor should be replaced or resurfaced. A thin or warped rotor will cause pedal pulsation and will wear out your brand-new pads prematurely.
Check the rubber boots on the caliper slide pins. If the boots are torn, moisture can enter and cause the pins to seize. Pull the pins out, wipe away the old crusty grease, and apply fresh silicone-based brake grease. This ensures the caliper can move freely as the pads wear down over time.
Experienced mechanics know that the hardware is just as important as the pads. If your new pad kit came with replacement springs or clips, use them. Reusing old, heat-cycled hardware can lead to uneven pad wear and annoying brake drag, which reduces your fuel economy.
Exiting Maintenance Mode and Final Testing
After you have finished both sides of the vehicle and the wheels are back on, you must exit the service mode. This resets the EPB motors to their operating position. The process is nearly the same as entering the mode, but with one key difference in the switch direction.
- Turn the ignition to ON (Engine OFF).
- Press and hold the accelerator pedal to the floor.
- Pull the Parking Brake Switch UP (in the apply position) and hold it.
- Turn the ignition OFF and then back to ON within five seconds.
The motors will whir again as they calibrate the distance to the new, thicker pads. The “Maintenance Mode” message will disappear. Before driving, pump the brake pedal several times until it feels firm. This seats the pads against the rotor and ensures you have immediate stopping power when you shift into gear.
Frequently Asked Questions About 2022 ford explorer rear brake pad replacement
Do I need to bleed the brakes during a pad replacement?
Generally, no. If you are only replacing pads and the hydraulic system was never opened, bleeding is not required. However, if the pedal feels spongy or you noticed a leak, a full brake fluid flush is highly recommended for safety.
Can I use ceramic pads on my Ford Explorer?
Yes, ceramic pads are an excellent choice for the 2022 Explorer. They produce less dust and are typically quieter than semi-metallic pads. They are ideal for daily driving, though heavy towers might prefer a heavy-duty semi-metallic compound for better heat dissipation.
What happens if I don’t use maintenance mode?
If you force the piston back without using maintenance mode, you will likely strip the internal plastic gears of the EPB motor. This results in a “Parking Brake Malfunction” light on your dash and requires a costly replacement of the entire caliper assembly.
How long should rear brake pads last on a 2022 Explorer?
On average, rear pads last between 30,000 and 50,000 miles. However, because the Explorer uses the rear brakes for stability control and traction management, they may wear faster than the front pads, especially if you drive in stop-and-go traffic or off-road conditions.
Mastering Your Explorer’s Maintenance
Completing a 2022 ford explorer rear brake pad replacement is a rewarding project that keeps your vehicle safe and your wallet full. By following the electronic service mode steps, you protect the advanced technology inside your SUV while ensuring mechanical longevity.
Remember to always work on a stable surface and double-check your torque values. Proper lubrication of the slide pins and hardware is the difference between a noisy brake job and a smooth, professional result. Take your time, stay organized, and enjoy the satisfaction of maintaining your own ride.
Brakes are your vehicle’s most vital safety system. If at any point you feel uncomfortable with the process or encounter a seized bolt you cannot move, do not hesitate to contact a certified mechanic. Stay safe, keep your tools clean, and enjoy the road ahead!
