Acura MDX Disc Brake Hardware Kit Guide: 2008-2014
Don't let worn clips and springs ruin your brake job; here's what you need for your MDX.
- Always replace your disc brake hardware kit when changing brake pads to prevent noise and uneven wear.
- For the 2008-2014 MDX, sticking hardware can contribute to overheating and the common issue of warped rotors.
- Choose aftermarket kits with stainless steel components for better corrosion resistance in harsh climates.
- While quality aftermarket brands work well, some owners prefer OEM hardware for a guaranteed perfect fit on Acura vehicles.
Is Your Brake Hardware Worn Out?
Old brake hardware is a common cause of brake problems. Because these small metal parts are constantly exposed to heat, water, and road salt, they corrode and lose their spring tension over time. When this happens, you might notice several issues with your MDX's brakes.
Symptoms of Failing Hardware:
- Brake Noise: Squealing, scraping, or rattling sounds, especially at low speeds, are a classic sign of worn or missing hardware.
- Sticking Brakes: If the clips are corroded, brake pads can get stuck. This can cause a grinding feeling, premature pad wear, and can lead to overheated, warped rotors.
- Uneven Pad Wear: When pads can't move freely, one pad might wear out much faster than the other, reducing the effectiveness of your brakes.
A Common MDX Problem: Warped Rotors
Many 2008-2014 MDX owners report a violent vibration or judder when braking on the highway. This is often due to warped brake rotors, a problem frequently linked to the vehicle's weight. While rotors themselves are the issue, failing brake hardware can contribute by causing calipers to stick and overheat the rotors. Replacing hardware during every brake job is a key preventative step.
Choosing the Right Aftermarket Hardware Kit
When you buy new brake pads for your MDX, it is highly recommended to also buy a new disc brake hardware kit. Reusing old, rusty clips is a recipe for noise and poor performance. Aftermarket kits are affordable and often made from high-quality materials.
OEM vs. Aftermarket Quality
For many cars, aftermarket hardware is just as good as the part you'd get from the dealer (OEM). However, some experienced mechanics note that for Honda and Acura vehicles, the fit of aftermarket hardware can sometimes be less precise than the original OEM parts. That said, high-quality aftermarket brands generally provide excellent results. The key difference is often the material. Many aftermarket kits use stainless steel, which offers better corrosion resistance than the plated steel found in some original or budget kits.
Pro Tip: The OEM hardware for the MDX is typically sold as part of the complete brake pad set from Acura. If you want guaranteed perfect fitment, buying the OEM pad set is an option, but quality aftermarket hardware kits are a cost-effective and reliable alternative.
Brand Tiers for Your Consideration
- Premium Brands (Best): Raybestos and Centric are well-regarded aftermarket brands that offer quality hardware kits. Centric is the parent company for performance brands like StopTech, and their parts are known for good fit and finish. Many users have good experiences with their products.
- Quality Standard Brands (Better): Dynamic Friction (DFC) is noted for using stainless steel components, which is a significant upgrade for longevity. Carlson is another reliable choice and is part of the same parent company as Raybestos and Centric.
- Economy Brands (Good): Dorman provides a wide range of replacement parts that meet basic requirements and are readily available. While functional, they may not have the same material quality or precise finish as premium lines.
How Much Should You Expect to Pay?
The cost for a new aftermarket disc brake hardware kit is low, making it an easy decision to replace during every brake service. The main cost difference comes from choosing between a standalone aftermarket kit and a complete OEM pad set that includes the hardware.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Hardware Kit (per axle) | $10.45 - $35.01 |
| New OEM Pad Set with Hardware (per axle) | $70 - $120 |
| Shop Labor (as part of brake job) | $110 - $161 |
Frequently Asked Questions (FAQ)
Do I really need to replace the hardware with every brake job?
Yes. It is one of the most important and lowest-cost parts of a brake job. Old hardware is often rusty and has lost its tension, which can lead to noise, binding, and uneven wear on your brand new pads and rotors. For the small price, it's cheap insurance for a quiet, long-lasting brake job.
What are abutment clips?
Abutment clips are the main metal pieces in the hardware kit. They snap into the caliper bracket where the "ears" of the brake pads make contact. They provide a smooth, clean surface for the pads to slide on. Without them, the pads would grind directly against the cast iron bracket, leading to rust, binding, and noise.
Will new hardware fix my brake noise?
It often does, especially if the noise is a rattling or light squeal from loose or binding pads. However, brake noise can have many causes, including the pad material itself or glazed rotors. Acura has issued service bulletins for other models regarding brake squeal that sometimes requires updated shims or pads to fix. New hardware is a critical step, but not a guaranteed fix for all noises.
Is installation difficult?
If you are already replacing your brake pads, replacing the hardware adds just a few minutes to the job. The old clips are pried out, the area on the caliper bracket is cleaned thoroughly with a wire brush, and the new clips are snapped into place. A small amount of high-temperature brake lubricant should be applied to the clips where the pads make contact. This is a task a DIYer can easily handle.
