2004-2007 Subaru Impreza Brake Parts, Pads & Rotors

The 2004-2007 Impreza is a light car by modern standards, roughly 2,900 pounds for a 2.5i sedan and a little over 3,300 for an STI, and that low curb weight is why the brakes feel so honest when everything is healthy. What complicates ownership is not mass, it is duty cycle. Symmetrical all-wheel drive means these cars get driven in slush, salt, and gravel that keeps other sedans parked, and they get driven in the twisties by owners who bought them for exactly that reason. The result is a predictable pattern: the friction material often lives a long time, while caliper slide pins, the rear parking-brake mechanism, and corroded rotor hats are what actually put the car in the shop. Subaru also used several different front rotor diameters across this generation, so buying brakes for a GD or GG chassis Impreza is mostly a matter of matching the right size to your specific trim.

Common brake symptoms on the 2004-2007 Subaru Impreza

• A steady squeal that goes away when you press the pedal harder. That is the wear indicator tab dragging on the rotor. It means the pads are near the end of usable material, not that the pads are defective.
• Pulsation through the pedal and a shimmy in the steering wheel under braking. On these cars it is almost always rotor thickness variation or lateral runout, usually from rust buildup between the rotor hat and hub, or from a sticking caliper heating one spot repeatedly.
• Rear pads worn out while the fronts still look fine. The rear calipers on this Impreza use an integral parking-brake lever. When the cable or the lever mechanism corrodes and stops fully returning, the pads stay lightly clamped and burn off early.
• The car pulls to one side when you brake. Seized slide pins with dried or washed-out grease are the usual cause in salt states, which leaves one side doing most of the work.
• A parking brake that will not hold on a hill, or one that will not release. Same rear caliper mechanism, plus stretched cables after a decade of winters.
• Soft or long pedal travel with no visible leak. Moisture-saturated brake fluid. Subaru's own interval is roughly every two to three years, and almost nobody honors it.
• Grinding, metal on metal. Stop driving it. The backing plate is cutting the rotor, and the rotor is now scrap regardless of how much thickness is left.

Recommended brake parts for your 2004-2007 Subaru Impreza

Before ordering, measure the diameter of a front rotor across its face. This generation shipped with different front sizes depending on trim and year, and that single measurement removes all the guesswork.

Complete front and rear coverage

The Front Rear Disc Rotors Brake Pads Kit for Subaru Forester Impreza Legacy at $253.99 covers all four corners in one order. This is the right call when the car has 100,000-plus miles and you already know the rear pads are thin or the parking brake has been weak, since doing both axles at once gets the whole system back to a known baseline instead of chasing a second job in six months.

Front brakes on the smaller rotor

The 10.91 inch Front Brake Rotors and Ceramic Pads Kit for Saab 9-2X, Subaru Impreza and Legacy at $146.99 is the budget-conscious daily driver choice. If you measure 10.91 inches up front, this is your kit. The ceramic compound runs clean, keeps wheel dust down, and stays quiet in stop-and-go commuting, which is what most naturally aspirated Imprezas actually do all week.

Front brakes on the larger rotor

The Subaru Front Brake Kit with Ceramic Pads, 11.54 inch, from Detroit Axle at $145.99 serves the larger front setup used on the sportier and heavier Subaru applications. If your measurement comes back near 11.5 inches, order this one. The bigger swept area gives you more thermal headroom for canyon roads, roof-rack loads, or a car that spends its life in hilly terrain.

How often should you replace 2004-2007 Subaru Impreza brakes?

Front pads typically last 35,000 to 60,000 miles. Rear pads on a healthy car can go 50,000 to 70,000, but on an Impreza with a sticky parking-brake lever they can be gone by 25,000. Rotors on this generation are usually replaced with the pads rather than resurfaced, because the factory discs are not thick enough to give up much material and rust-jacking at the hat surface causes runout that machining will not permanently fix. Short trips in a salt-belt winter, aggressive downhill driving, and towing a small trailer all push those numbers to the low end. Highway commuting in a dry climate pushes them to the high end. Flush the fluid every two to three years no matter the mileage, and grease the slide pins every time the calipers come off. That one habit prevents most premature wear on these cars.

Core Brake Parts stocks fitment-verified brake kits for the 2004-2007 Impreza, so you are matching parts to your actual car instead of gambling on a generic listing. Orders over $75 ship free, every kit above clears that threshold, and we ship fast because a car on jack stands is a car you cannot drive. If you are unsure which front rotor size your Impreza uses, measure the disc and order with confidence.
