2006-2012 Ford Fusion Brake Job Guide: Symptoms, Costs and the Right Parts

By Core Brake Parts Tech Team — Circleville, OH warehouse

A full brake job on a 2006-2012 Ford Fusion means front pads and rotors, rear pads and rotors, new hardware and a fluid check, because every Fusion of this generation has disc brakes at all four corners. The fronts usually go first on the gas models, while the Hybrid is known to wear its rears faster. Before any brake work on a 2006-2010 car, check whether Ford safety recall 19S54 has been done, because it changes which brake fluid belongs in the system.

How the Fusion Brake System Is Built

The first-generation Fusion (and its twins, the Mercury Milan and Lincoln Zephyr/MKZ) rides on Ford's CD3 platform. According to Brake and Front End's service write-up on this car, the brake systems on all variants use discs front and rear, and anti-lock brakes became standard in 2008. That means there are no drum brakes or brake shoes to service on this car - a rear brake job is a rear disc job.

The rear calipers do double duty. The parking brake is built into the rear caliper, and the caliper piston is a screw-type piston. It does not push straight back like a front piston; it has to be wound back into the bore, and its notch has to line up with the pin on the back of the inboard pad. That one detail is where most first-time Fusion rear brake jobs go wrong.

The 2010-2012 Fusion Hybrid adds regenerative braking. On light stops the electric motor does most of the slowing, and the friction brakes come in near or at a stop. Tomorrow's Technician notes that it is normal for a Ford hybrid to wear its rear pads two to three times faster than the fronts, which is the opposite of the usual pattern on the gas cars.

Symptoms Your Fusion Is Due for Brakes

• Squeal when braking - usually the pad wear indicator touching the rotor. Check the thinnest pad, not just the one you can see through the wheel.
• Grinding - the pad material is gone and the steel backing plate is cutting the rotor. At this point the rotors are part of the job.
• Pulsation in the pedal or steering wheel - rotor thickness variation. Front rotor problems tend to show up through the steering wheel; rear problems through the pedal and seat.
• Pull to one side - often a sticking caliper slide pin or a seized piston on one side.
• Long or soft pedal - on a 2006-2010 car this can be the ABS valve problem covered by the recall below, not just worn pads or air in the lines. Have it diagnosed before driving on it.
• Parking brake that holds poorly or drags - the rear caliper's parking brake mechanism or its adjustment.
• Falling brake fluid level - as pads wear, the caliper pistons move out and the reservoir level drops. Ford's own guidance is to have the brakes inspected if the level keeps going down or the fluid is dark.

Recall 19S54: Check This Before You Touch the Fluid

Ford safety recall 19S54 (NHTSA campaign 19V904) covers certain 2006-2010 Fusion, Milan, MKZ and Zephyr vehicles with anti-lock brakes, built at Hermosillo between February 22, 2006 and July 15, 2009. Ford's dealer bulletin explains that aged DOT 3 brake fluid can react with zinc plating inside the ABS hydraulic control unit and form a gel, which can hold a normally closed valve open and cause extended brake pedal travel. Ford states the condition does not cause a loss of braking function.

The remedy: the dealer tests the hydraulic control unit, replaces it if it fails, pressure-flushes the system with DOT 4 fluid, replaces the DOT 3 reservoir cap with a DOT 4 cap and gives the owner an updated owner's guide insert. The work is free. So before a brake job on one of these cars:

• Run the VIN through NHTSA's recall lookup or a Ford dealer.
• Look at the reservoir cap. If the recall has been done, the cap is marked for DOT 4, and that is the fluid to top up and bleed with.
• Never add DOT 5 (silicone) fluid. Ford warns that DOT 5 should never go into a vehicle that specifies DOT 3 or DOT 4.

2011 and 2012 models are outside this recall; use the fluid your owner's manual and reservoir cap specify.

Front vs Rear: What Each Axle Involves

The rear rotors are thin to begin with, so there is very little material to machine. In practice, rotors that have been ground into, warped or are near the minimum are replaced rather than resurfaced. Always go by the minimum thickness cast into your rotor, since that is the spec for the exact part on the car.

What to Replace Together

• Pads and rotors as a set, by axle. New pads on worn or grooved rotors bed in poorly and often bring the noise or pulsation right back. Shop brake pads and brake rotors for the Fusion, or pick ceramic brake pads for low dust and quiet daily driving.
• Hardware. Brake and Front End recommends new pad retraction springs on this car, citing a small fuel economy gain and less brake noise. A brake hardware kit covers the clips and springs.
• Calipers when they are the problem. A rear caliper whose piston will not wind back smoothly, leaks, or leaves the parking brake dragging should be replaced rather than forced. See brake calipers.
• Flexible hoses if they are cracked or swollen, or the car pulls under braking. See brake hoses.
• Fluid. A pad job is a good time to bleed or flush, using the fluid the cap and owner's guide call for.

How Hard Is the Job?

The front brake job is straightforward for a home mechanic with basic hand tools and a torque wrench: remove the caliper, hang it from the suspension, remove the bracket, swap the rotor, clean and lubricate the slide pins and pad abutments, install the new pads and hardware, and torque everything back to spec. Brake and Front End lists the fastener torques for this generation; use those or the values in the factory service manual rather than going by feel.

The rear is moderately harder because of the screw-in piston. You need a caliper wind-back tool, and the piston notch must be clocked so the pin on the inboard pad seats in it. After the job, check the parking brake. Brake and Front End describes the check: slight drag at the rear wheels at two clicks and no wheel movement at five clicks. Snug the bleeder screws to spec after bleeding so they do not crack.

On the Hybrid, extra care applies. Tomorrow's Technician advises disconnecting the 12-volt battery before removing the calipers so the brake system does not activate while you work, and notes that a scan tool and pressure bleeder are needed if air gets into the master cylinder or ABS unit. A simple pad and caliper job that keeps air out of those components does not need them.

What drives the cost of a Fusion brake job: pads only versus pads and rotors, one axle versus both, whether a rear caliper needs replacing, whether a fluid flush is added, and whether you pay for labor or do it yourself. Rear jobs take a little more labor because of the wind-back piston and parking brake check.

Once the job is done, bed the new pads with a series of moderate stops from moderate speed, without coming to a full stop and holding the brakes, so a layer of pad material transfers evenly to the rotors.

Frequently Asked Questions

Does the 2006-2012 Ford Fusion have rear drum brakes?

No. Per Brake and Front End's service article on this platform, all variants use disc brakes at all four corners. A rear brake job means rear pads and rotors, not shoes and drums.

Why will my Fusion's rear caliper piston not push back?

The rear piston is a screw type tied to the parking brake. It has to be turned back into the bore with a wind-back tool, not pushed with a C-clamp. Forcing it can damage the parking brake mechanism.

Should I use DOT 3 or DOT 4 brake fluid in my Fusion?

Check the reservoir cap and owner's guide. Many 2006-2010 cars came with DOT 3, but if recall 19S54 was performed, the system was flushed with DOT 4 and the cap was changed to a DOT 4 cap. Use DOT 4 in that case, and never use DOT 5.

Why are the rear pads on my Fusion Hybrid wearing out first?

Regenerative braking handles most light stops, and the friction brakes are applied near or at a stop. Rear pads wearing two to three times faster than the fronts is considered normal on Ford hybrids.

Can I replace just the pads and keep the rotors?

Only if the rotors are smooth, not warped, and well above their minimum thickness. The rear rotors on this car are thin to start with, so most worn rear rotors are replaced along with the pads.

Do the Mercury Milan and Lincoln Zephyr/MKZ use the same brake setup?

They share the Fusion's CD3 platform and are covered by the same 19S54 recall for 2006-2010, but always confirm parts by year, model and trim before ordering.
