2015–2017 Ford Edge Rear Brake Replacement With Electronic Parking Brake

Confirm the part and repair scope

Whether you are planning a 2015 Ford Edge rear brake replacement or working on a 2017 model, confirm vehicle fitment by VIN rather than by model year alone. Rotor diameter, pad shape, and caliper details can differ between trims, engines, and option packages within the same generation. A pad set that looks close but does not match can sit unevenly in the bracket, bind on the clips, or contact the rotor only partially.

Next, make sure new parts will actually fix the problem. Measure the remaining friction material on both inner and outer brake pads, and measure rotor thickness at several points. Compare those figures with the wear limits in the service information or the minimum thickness stamped on the rotor. Uneven wear between the inner and outer pad, or between the left and right side, often points to seized slide pins, a sticking piston, or a caliper that is not fully releasing. Those faults need attention along with the pads. An electronic parking brake warning or a fault message is a separate issue. New pads will not cure a failed motor, a wiring fault, or a module problem, so read stored fault codes before you buy parts.

Prepare tools and safe access

The key requirement is a way to put the electronic parking brake into its service or maintenance mode. This is usually done with a scan tool that supports Ford parking brake functions. Some vehicles also have a control-based procedure described in Ford service information. If you have neither, do not start the job. Forcing the piston back while the motor mechanism is engaged can damage the caliper and the motor drive. This is one reason the work is not a good first brake job for an inexperienced owner.

You also need a quality jack, jack stands rated for the vehicle, wheel chocks, a torque wrench, the correct sockets, a piston compression tool, brake cleaner, high-temperature brake lubricant, and fresh brake fluid of the type Ford specifies. Have a hook or wire to support the caliper as well. Make sure the battery is healthy, because a low voltage can interrupt the motor while it is retracting or reapplying. Work on level ground with the transmission in Park and chock the front wheels. Once service mode releases the rear brakes, the parking brake will not hold the vehicle.

Remove without avoidable damage

With the wheels on the ground and chocked, enter service mode as the applicable procedure describes. Confirm the motors have fully retracted, which is usually shown by a dash message, the motor sound stopping, or a confirmation on the scan tool. Follow the instructions on ignition state. Then loosen the lug nuts, raise the vehicle, support it on stands, and remove the wheel. Do not apply battery voltage directly to the parking brake motor to drive it, and do not separate the motor from the caliper unless the service information calls for it. Its seal and drive interface are easy to damage.

Disconnect the motor connector if your procedure requires it, then remove the caliper slide bolts and lift the caliper off the pads. Support it on a hook so it does not hang by the brake hose or the parking brake wiring. Remove the pads and hardware clips. If you are replacing rotors, remove the caliper bracket and then the rotor. A rusted rotor may need penetrating oil and controlled taps on the outer area. Heavy blows near the hub can harm the wheel bearing.

Push the piston back into its bore with a suitable compression tool, keeping it square. Do not rotate it unless the service information for your caliper says to. Watch the brake fluid reservoir as you do this, because fluid displaced from both rear calipers can make it overflow and brake fluid damages paint.

Install and restore the system

Clean rust and debris from the bracket abutments and the hub face. Rust on the hub can cause rotor runout and a pulsing pedal later. Clean any protective coating from new rotors as the manufacturer directs. Fit new hardware clips, and clean and lubricate the slide pins with a lubricant compatible with their boots. Keep grease and fingerprints off the friction surfaces. Check whether the inner and outer pads differ in shape, backing, or wear-indicator position, and install each one in its correct location and orientation.

Reinstall the bracket and caliper, and torque every fastener to the Ford specification for your vehicle. Some bolts may require threadlocker or must be replaced rather than reused, so follow the service information. Reconnect the motor connector, make sure it is fully latched, and clip the harness back into its routing so it cannot touch the wheel or suspension. Mount the wheels and torque the lug nuts in a cross pattern to specification.

Pump the brake pedal until it is firm before attempting anything else. Then exit service mode with the scan tool or the applicable procedure, which drives the parking brake mechanism back to its working position. Apply and release the parking brake several times so the system can settle the running clearance. If the scan tool offers a calibration or adjustment routine for the rear calipers, complete it as instructed.

Check the completed work

Before moving the vehicle, check the brake fluid level and correct it with the specified fluid. Look for leaks at each caliper and hose. Confirm that the parking brake warning lamp goes out and stays out, that no new fault codes are stored, and that both rear motors apply and release cleanly. The pedal should feel firm and consistent. Confirm the parking brake holds the vehicle as described in the service information, then make a slow test drive in a safe area before any normal driving. Bed in the new pads according to the pad maker's recommendations.

Some signs mean you should stop and diagnose further. These include a soft or sinking pedal, the vehicle pulling to one side, grinding or scraping, one rear wheel much hotter than the other after a short drive, a burning smell, or a parking brake warning that returns. These can point to a caliper that is not releasing, an incorrectly seated pad, air in the system, or a fault in the electronic parking brake circuit. If any of them appear, do not keep driving. Have the system inspected by a qualified brake technician with Ford diagnostic capability.
