1993-1997 Ford Probe Front vs Rear Brakes: What Wears First and What to Replace

By Core Brake Parts Tech Team — Circleville, OH warehouse

On a 1993-1997 Ford Probe, the front brakes almost always wear out first. The front discs do most of the stopping work, so expect to replace front pads (and often rotors) at least once, and frequently twice, for every time the rear brakes need service. What you replace at the rear depends on your trim: base four-cylinder Probes use rear drums and shoes, while the V6 Probe GT has disc brakes at all four corners.

Which Rear Brakes Does Your Probe Have?

This is the first thing to settle before you order parts, because the 1993-1997 Probe was built with two different rear brake setups. Consumer Guide's review of this generation notes that base Probes use rear drums, while all-disc brakes stop the GT. Anti-lock brakes were optional on both trims, so an ABS-equipped base car still has drums out back.

The quickest way to confirm is to look through the rear wheel spokes. If you see a flat rotor face and a caliper, you have rear discs. If you see a closed drum with no caliper, you have drums. Trim badges are not always reliable on a car this old, since parts and even whole assemblies get swapped over the years.

The second-generation Probe shares its chassis with the Mazda MX-6 and 626 of the same era, which is why many Probe brake parts are listed as fitting those Mazdas too. Hawk, for example, lists its front pad for the 1993-97 Probe, 626 and MX-6 as a single application. When you shop, still confirm fitment by year and by rear brake type, not by platform alone.

Why the Front Brakes Wear First

When you brake, the car's weight shifts forward onto the front tires. The front tires then have more grip, so the brake system is designed to put more of the stopping force there. The Motorist Assurance Program puts the front share at about 70 percent of braking force on a typical vehicle. The Probe adds to this: it is a front-wheel-drive car with the engine and transaxle sitting over the front wheels, so the nose is heavy even before the weight shift.

The result is predictable. Front pads wear faster, front rotors run hotter and are more likely to develop thickness variation that you feel as a pulsing pedal, and front caliper slide pins see more heat cycles. The rear brakes, whether drums or discs, mostly add stability and keep the car straight in a hard stop.

That said, "the rears last longer" does not mean "the rears never need attention." On a car that is now around 30 years old, age and corrosion often retire rear brake parts before friction wear does.

Symptoms and How to Tell Front from Rear

Front brake problems

• Squeal or grinding from the front when braking, often the wear indicator or pads worn to the backing plate.
• Pedal pulsation or steering wheel shake under braking, usually front rotor thickness variation.
• Pulling to one side, commonly a sticking front caliper or seized slide pin.

Rear drum problems (base models)

• Parking brake lever pulls up very high before holding. This usually means the shoes are worn or the self-adjusters have stopped working.
• Low or long brake pedal that improves after pumping, another sign of out-of-adjustment shoes.
• Scraping from the rear, or a wet, dirty inside of the rear tire, which can point to a leaking wheel cylinder.

Rear disc problems (GT)

• Rear grinding or a rusted-lip rotor, since rear rotors on lightly used brakes corrode more than they wear.
• Weak parking brake or a dragging rear wheel that runs hot after a drive, often a rear caliper that is sticking.

A simple check after a normal drive: carefully hold the back of your hand near each wheel without touching it. One wheel much hotter than the others usually means a brake at that corner is dragging.

What to Replace at the Front

Front service on every 1993-1997 Probe is a pad-and-rotor job. Replace pads in axle sets, both sides at once. Rotors on a car this age are often worn close to their minimum thickness (the figure is stamped on the rotor) or carry a heavy rust ridge, so new rotors are usually the better choice over machining. Our brake pads and brake rotors collections cover the Probe front axle, and ceramic brake pads suit a daily driver because they run quiet and dust less than semi-metallic pads.

At the same time:

• Clean and lubricate the caliper slide pins, and replace torn pin boots.
• Install new abutment clips from a brake hardware kit; old clips are a common cause of noise and uneven pad wear.
• Look over the rubber front hoses. On a 30-year-old car, cracked or swollen hoses are worth replacing. See our brake hoses.
• Check the caliper piston boots. If a boot is torn or the piston is seized, a replacement from our brake calipers collection is a cleaner fix than forcing an old one back into service.

What to Replace at the Rear

Base models with rear drums

Drum shoes wear slowly, but the hardware around them is what usually fails. Drum brakes use self-adjusters, a lever and notched star wheel that take up clearance as the linings wear. The Know Your Parts technical library notes that adjustment happens when the brakes are applied in reverse or when the parking brake is engaged, and that grooves worn into the lever and wheel can stop the adjuster from working. It recommends replacing the adjusters during a shoe job, because the adjuster does most of its work in the first 100 miles or so on new shoes.

A complete rear drum job on a base Probe usually includes new brake shoes, a spring and adjuster hardware kit, and drums if they are scored or worn past the maximum diameter cast into the drum. Inspect the wheel cylinders for leaks; brake fluid on the linings ruins new shoes. After assembly, set the initial shoe adjustment by hand. R1 Concepts makes the point that self-adjusters maintain an already established setting; they are not a substitute for setting it correctly on install.

GT models with rear discs

The GT rear axle takes pads and rotors, and on this car the rear caliper also handles the parking brake. Rear pads wear slower than fronts, but rear rotors often need replacing because of rust rather than wear. If the rear caliper piston will not push straight back when you service the pads, do not force it: many rear calipers with an integral parking brake need the piston rotated back in, and the factory service manual describes the correct method for this car. A seized rear caliper or parking brake mechanism is a common reason for a dragging rear wheel on a GT.

If both axles are due, a matched front and rear kit saves you from sourcing parts one at a time. We carry a 1993-1997 Ford Probe front and rear brake kit from R1 Concepts. Confirm that the kit matches your rear brake type before ordering, since a rear pad-and-rotor kit only fits rear-disc cars.

Fluid, Lines and the Rest of the System

Brake fluid absorbs moisture over time, and on a car this old the fluid may not have been changed in years. Flush it when you do a brake job, using the DOT fluid specified on the master cylinder reservoir cap or in your owner's manual. Air in the lines or old fluid can give a soft pedal even with new pads and shoes. Check the steel lines where they run under the car for rust scaling, and if the pedal still sinks slowly after the system is bled, the master cylinder may be bypassing internally.

Torque the caliper bolts and lug nuts to the values in the factory service manual, and tighten lug nuts in a star pattern so you do not distort the new rotors.

How Hard Is the Job?

Front pads and rotors on a Probe are a reasonable first brake job for a home mechanic with a floor jack, jack stands, a piston tool, and a torque wrench. Plan on a couple of hours for the front axle if nothing is seized.

Rear drums take more patience. Springs and adjusters must go back exactly as they came off, so do one side at a time and use the other side as a reference. GT rear discs are straightforward except for the parking brake piston, which is where most first-timers get stuck. Either way, bed in new pads with a series of moderate stops before any hard braking.

Frequently Asked Questions

Should I replace front and rear brakes at the same time on my Probe?

Only if both are worn. Fronts usually need service far more often. Inspect the rears every time you do the fronts, and replace them when the friction material, drums or rotors are worn or the hardware is corroded.

Does my Ford Probe have rear drum or rear disc brakes?

Base 1993-1997 Probes with the four-cylinder use rear drums. The V6 GT uses rear discs. Look through the rear wheel to confirm, since parts may have been changed over the years.

Do Mazda MX-6 or 626 brake parts fit a Ford Probe?

Many do, because the 1993-1997 Probe shares its platform with the MX-6 and 626 of that period. Always confirm the exact year and rear brake type, though, since drum and disc cars take different parts.

Why does my parking brake lever pull up so high?

On a base Probe with drums, it usually means worn shoes or self-adjusters that have stopped working. On a GT, it can point to worn rear pads or a sticking rear caliper parking brake mechanism.

Are ceramic pads a good choice for a Probe?

For street driving, yes. Ceramic pads run quiet and produce less visible dust. Track-oriented compounds are also made for this car but bring more noise, dust and rotor wear, so they only make sense if you autocross or do track days.
