In this article, we will preview the entire process from lifting the vehicle to bedding in your new friction materials. Let’s get your Fusion back on the road with the stopping power it deserves.
Essential Tools for Servicing 2010 ford fusion rear brakes
Before you start turning wrenches, you need the right gear for the job. Working on the 2010 ford fusion rear brakes is unique because a standard C-clamp will not work on the rear calipers.
The rear pistons on this vehicle are integrated with the parking brake mechanism. This means they must be rotated while being compressed, or you risk damaging the internal gears of the caliper assembly.
Gather these items before you begin:
- Brake Piston Tool Kit: Often called a “wind-back” or “cube” tool.
- Sockets and Wrenches: You will specifically need 13mm and 15mm sizes.
- Brake Cleaner: To remove the protective shipping oil from new rotors.
- High-Temp Brake Grease: Essential for the caliper sliding pins and pad contact points.
- Jack and Jack Stands: Never work under a car supported only by a floor jack.
- Wire Brush: To clean corrosion off the hub and caliper bracket.
Choosing the Right Brake Pads
When selecting parts for your 2010 ford fusion rear brakes, you generally have two choices: ceramic or semi-metallic. Ceramic pads are quieter and produce less dust, making them ideal for daily commuting.
Semi-metallic pads offer better heat dissipation if you drive in hilly areas or carry heavy loads. For most Fusion owners, a high-quality ceramic pad provides the best balance of longevity and comfort.
Step 1: Preparation and Safety First
Park your vehicle on a flat, level surface like a garage floor or a paved driveway. Engage the transmission in “Park” and place wheel chocks in front of the front tires to prevent the car from rolling.
Loosen the lug nuts on the rear wheels while the car is still on the ground. Use a 19mm socket or the lug wrench provided in your trunk, but do not remove the nuts yet.
Lift the rear of the car using the factory-approved jacking points. Secure the vehicle on jack stands placed under the frame rails to ensure a stable working environment.
Releasing the Parking Brake
This is a critical step that many beginners forget. Ensure the parking brake handle inside the cabin is completely disengaged before you attempt to remove the caliper.
If the parking brake is on, the tension on the cable will make it impossible to pull the caliper off the rotor. Double-check this before you move forward to avoid frustration.
Step 2: Removing the Old Brake Components
Once the wheel is off, you will see the caliper assembly. Locate the two 13mm bolts on the back of the caliper that hold it to the mounting bracket.
Hold the 15mm slide pin nut with a thin wrench if it starts to spin while you loosen the 13mm bolt. Carefully pull the caliper away from the rotor and suspend it with a bungee cord.
Never let the caliper hang by the rubber brake hose. The weight of the metal can cause internal damage to the line, leading to a dangerous brake failure later.
Inspecting the Caliper Bracket
Remove the old brake pads from the bracket. Take note of how the metal shim clips are positioned, as you will need to replace these with the new ones included in your kit.
If you are replacing the rotors, you must remove the two larger bolts holding the caliper bracket to the knuckle. These are usually very tight, so a breaker bar might be necessary here.
Step 3: Servicing the 2010 Ford Fusion Rear Brakes Piston
This is the most technical part of the job. The piston on the 2010 ford fusion rear brakes features two small indentations or notches on its face.
Select the correct adapter from your brake tool kit that fits into these notches. Turn the tool clockwise while applying steady pressure to “screw” the piston back into the housing.
If the piston feels stuck, check your brake fluid reservoir under the hood. Removing the cap can sometimes relieve back-pressure, making it easier to retract the piston fully.
Aligning the Piston Notches
Pay close attention to the final position of the piston notches. One of the notches must be perfectly vertical (at the 12 o’clock position) to line up with the pin on the back of the new brake pad.
If these are not aligned, the brake pad will sit at an angle. This causes uneven wear, annoying vibrations, and significantly reduced stopping power.
Step 4: Rotor and Bracket Preparation
If your old rotors have deep grooves or a “lip” around the edge, they must be replaced. Slide the old rotor off the wheel studs; a few taps with a rubber mallet may be needed to break it loose.
Use a wire brush to clean the rust off the hub surface. A clean mating surface prevents “rotor runout,” which is the primary cause of a pulsating brake pedal.
Spray your new rotors with brake cleaner to remove the oily film applied at the factory. This film is meant to prevent rust during shipping but will ruin your new pads if left on.
Lubricating the Slide Pins
Pull the sliding pins out of the caliper bracket and wipe away the old, crusty grease. Apply a fresh coat of silicone-based brake lubricant to the pins before sliding them back in.
Ensure the rubber boots are seated correctly and are not torn. Seized slide pins are a common reason why the 2010 ford fusion rear brakes wear out prematurely on one side.
Step 5: Reassembly and Torque Specs
Slide the new rotor onto the studs. I like to thread one lug nut on by hand to hold the rotor flush against the hub while I work on the bracket.
Reinstall the caliper bracket and tighten the bolts firmly. Install the new stainless steel hardware clips and then slide your new ceramic brake pads into the slots.
Lower the caliper over the pads. Ensure the pin on the back of the inner pad fits into the notch you aligned on the piston earlier.
Final Tightening
Hand-start the two 13mm caliper bolts to avoid cross-threading. Once they are snug, tighten them to approximately 20-25 foot-pounds of torque.
Replace the wheel and tighten the lug nuts in a star pattern. Lower the vehicle to the ground and finish tightening the lug nuts to 100 foot-pounds.
Step 6: Testing the System Safely
Before you shift into gear, you must pump the brake pedal several times. The first few pumps will go to the floor as the piston extends to meet the new pads.
Continue pumping until the pedal feels firm and responsive. Check the brake fluid level in the reservoir and add more DOT 3 fluid if it has dropped below the “MIN” line.
Test the parking brake by engaging and releasing it a few times. It should feel tight and hold the car firmly on an incline.
The Bedding-In Procedure
To get the longest life out of your 2010 ford fusion rear brakes, you need to “bed” them. This involves a series of controlled stops to transfer a layer of pad material onto the rotor.
Drive at 30 MPH and slow down firmly to 5 MPH, but do not come to a complete stop. Repeat this 5 times, then drive for a few minutes without using the brakes to let them cool down.
Frequently Asked Questions About 2010 Ford Fusion Rear Brakes
Why do my rear brakes wear out faster than the fronts?
Modern vehicles like the Ford Fusion use Electronic Brakeforce Distribution (EBD). This system applies the rear brakes first during light braking to keep the car level, which can lead to faster rear pad wear.
Can I use a C-clamp to push the rear piston in?
No. Using a C-clamp on the 2010 ford fusion rear brakes will likely break the internal parking brake actuator. You must use a tool that rotates the piston while compressing it.
How often should I check my rear brakes?
You should inspect your brake pads every 10,000 to 15,000 miles. If the friction material is less than 3mm thick, it is time for a replacement to avoid damaging the rotors.
What causes the “grinding” noise when I brake?
Grinding usually means the friction material is completely gone, and the metal backing plate is rubbing against the rotor. This requires immediate replacement of both pads and rotors.
Summary of Key Takeaways
Taking care of your 2010 ford fusion rear brakes is a rewarding DIY project that enhances your vehicle’s safety. By using the correct wind-back tool and ensuring proper piston alignment, you avoid the most common mistakes made by beginners.
Remember to always clean your new rotors, lubricate your slide pins, and pump the pedal before driving. These small details make the difference between a professional-grade job and a noisy, vibrating mess.
Stay safe, take your time, and enjoy the satisfaction of maintaining your own ride. You’ve got this!
