2023-2024 Acura Integra Front vs Rear Brakes: What Wears First and What to Replace

Brake pads and rotors for the 2023-2024 Acura Integra front and rear

By Core Brake Parts Tech Team — Circleville, OH warehouse

On a 2023-2024 Acura Integra the front brakes almost always wear out first. The Integra is a front-engine, front-wheel-drive car, so most of the stopping work lands on the front axle, and the front pads usually need replacing well before the rears. The rears still wear, though, and because they carry the electric parking brake, a rear job on this car has a few extra steps you should know about before you start.

How the Integra brake system is laid out

Every 2023-2024 Integra uses disc brakes at all four corners with a hydraulic system, ABS and Vehicle Stability Assist (VSA). There are no rear drums on this generation. What changes between trims is the size of the hardware.

Trim Front rotor Front caliper Rear rotor Parking brake
Integra and A-Spec (1.5L turbo) About 12.3 in (1.5 in smaller than Type S) Sliding caliper About 11.1 in (0.9 in smaller than Type S) Electric, motor at rear caliper
Integra Type S (2024) 13.8 in two-piece Brembo 4-piston monobloc aluminum 12.0 in Electric, motor at rear caliper

Acura states the Type S front rotors are 1.5 inches larger and the rears 0.9 inches larger than the standard Integra, which is where the base-car figures above come from. Acura also routes air through functional ducts in the Type S front fascia to cool the front rotors, a sign of how much heat the front axle handles on that car. Parts for the Type S and the 1.5L cars are not interchangeable, so always shop by trim, not just by year.

Why the fronts wear first

When you brake, the car's weight pitches forward. On a front-drive sedan like the Integra, the engine and transaxle already sit over the front wheels, so the front brakes do the large majority of the stopping. The front rotors are bigger to deal with that heat, and the front pads carry more material, but they still wear faster.

The rear brakes do less work, but modern stability systems use them too. VSA can apply individual brakes to keep the car straight, and the Integra's Brake Hold and electric parking brake also clamp the rear pads. That is why rear pads on late-model cars do not outlast the fronts as dramatically as they did on older cars with rear drums. A reasonable expectation on a car like this: fronts get replaced more often than rears, but inspect both every time the wheels come off rather than guessing.

Driving style shifts this a lot. Stop-and-go city driving, hilly roads and riding the brake pedal all shorten pad life. The owner's manual specifically warns against resting your foot on the brake pedal while driving because it reduces braking effectiveness and pad life.

Symptoms and how to tell which end needs work

  • Continuous metallic squeal when braking. The manual for the 2023 Integra says a continuous metallic friction sound when you apply the brakes is the wear indicator rubbing the rotor, and it means the pads need replacing. Note which corner it comes from; the indicator tab is on the pad, so the noisy corner is the worn one.
  • Grinding. Pads are past the indicator and metal is contacting the rotor. The rotor on that axle will almost certainly need replacement too.
  • Pulsation in the pedal or steering wheel. Steering-wheel shake under braking points to the front rotors. A pulsing pedal with a steady wheel can be the rears.
  • Red brake system indicator. The 2024 manual says the red brake indicator comes on for low brake fluid or a brake system malfunction. Low fluid is often just worn pads (the caliper pistons have moved out, drawing fluid from the reservoir), but it can also be a leak. If the pedal feels abnormal, have it repaired immediately.
  • Blinking red brake indicator. Per the manual, that means a problem with the electric parking brake system. Avoid using the parking brake and get it checked.

The most reliable check is visual: pull the wheels and look at remaining pad material on both the inner and outer pad at each corner. Uneven inner-to-outer wear usually means a caliper slide pin that needs cleaning and fresh grease.

Check the VSA modulator recall first

NHTSA campaign 23V430000 covers certain 2023 Integra models (along with some Civic, RDX and Accord models). A ball valve in the VSA modulator may leak brake fluid, which can cause an unexpected increase in pedal travel or unintended vehicle movement when Brake Hold is engaged. If your Integra has a soft or long pedal, or the brake fluid level keeps dropping with no visible leak at the wheels, run your VIN through the NHTSA recall lookup before you replace anything. Recall repairs are done by the dealer at no charge.

What to replace, and what to replace with it

Front brake job

Replace pads in axle sets, never one side. On a car that has reached the wear indicator, fresh front brake rotors are usually the right call too; a new pad on a worn or grooved rotor beds in poorly and can squeal or pulse. Clean and lubricate the caliper slide pins, install new abutment clips from a brake hardware kit, and look over the flex hoses while you are there. Ceramic compound is a good match for a daily-driven Integra; browse ceramic brake pads for low dust and quiet operation.

Rear brake job

The rears on the 1.5L cars use a smaller pad and rotor than the front. For a direct replacement set, see our 2023-2024 Acura Integra rear ceramic brake pads by Bendix. Check rear rotor condition the same way you do the fronts and replace them in pairs if they are scored or below the minimum thickness cast into the rotor.

Brake fluid

Brake fluid absorbs moisture over time. Use only the fluid type printed on the reservoir cap and in the owner's manual, and follow the maintenance minder for the flush interval. Do not top off right before a pad job; pushing the pistons back will raise the level and can overflow the reservoir.

How hard is the job?

A front pad and rotor job on the 1.5L Integra is a standard sliding-caliper job: jack, stands, remove the caliper and bracket, swap the rotor, compress the piston, install pads and hardware. A home mechanic with basic tools and a torque wrench can handle it. Torque every fastener to the values in the factory service manual; do not guess on caliper bracket bolts.

The rear is where people get caught. The electric parking brake motor works at the rear calipers, and the manual notes you may hear that motor running from the rear wheel area when the brake is applied or released. Before you touch the rear caliper, the parking brake must be fully released and put into its service mode with a compatible scan tool or the procedure in the service manual. Forcing the piston back while the actuator is engaged can damage it. If you do not have a scan tool that supports the Integra's electric parking brake, the rears are a reasonable job to hand to a shop even if you do the fronts yourself.

The Type S is a different job. The Brembo 4-piston front calipers are fixed, so the pads come out without unbolting the caliper, but the two-piece rotors and pads are specific to that car. Buy Type S parts by trim.

After any brake job, bed the new pads in with a series of moderate stops from moderate speed, letting the brakes cool between runs, and avoid a hard panic stop for the first few miles. You can find more options in our brake pads collection.

Frequently Asked Questions

Do the front or rear brakes wear first on a 2023-2024 Acura Integra?

The fronts, in nearly every case. The Integra is front-wheel drive and the front axle handles most of the braking load. Rear pads still wear, partly because stability control, Brake Hold and the electric parking brake use them, so inspect both ends.

Does the 2023 Integra have rear drum brakes?

No. The 2023-2024 Integra uses rear disc brakes, with the electric parking brake working at the rear calipers.

Do I need a scan tool to change the rear brake pads?

You need a way to put the electric parking brake into service mode before retracting the rear pistons, which normally means a scan tool that supports the Integra, or following the exact procedure in the factory service manual.

Are Integra Type S brake parts the same as the regular Integra?

No. The Type S uses 13.8-inch two-piece front rotors with Brembo 4-piston calipers and 12.0-inch rear rotors, all larger than the standard Integra. Pads and rotors are trim-specific.

What does a squealing noise mean on my Integra brakes?

The owner's manual says a continuous metallic friction sound while braking is the wear indicator touching the rotor, which means the pads should be replaced.

Should I replace rotors every time I replace pads?

Not always, but if the rotors are grooved, warped, below minimum thickness, or the pads reached metal-to-metal, replace them. New pads on a worn rotor often cause noise and pulsation.
