Essential Guide to the 2014-2019 Lexus ES350 Disc Brake Hardware Kit
Ensure your Lexus ES350 stops smoothly and quietly by understanding when and why to replace your disc brake hardware.
- Always replace brake hardware when changing brake pads to ensure quiet operation and even wear.
- A front brake squeal on 2019 models is a known issue addressed by a TSB with an updated hardware kit.
- Quality aftermarket brands like Beck Arnley and Centric offer excellent value and performance for the ES350.
- Failure to replace worn hardware can lead to noise, uneven pad wear, and sticking brakes.
Symptoms of Failing Brake Hardware on Your ES350
Worn or corroded brake hardware can cause several noticeable problems. Since these parts are constantly exposed to heat, moisture, and road salt, they can lose their tension or seize over time. It's best practice to replace the hardware every time you replace your brake pads and rotors.
- Brake Noise: A rattling, squealing, or clunking sound when you apply or release the brakes is a primary symptom. This happens when worn clips fail to hold the brake pads tightly.
- Uneven Brake Pad Wear: If the guide pins in the hardware kit are sticking, the brake pads won't apply or release evenly. This leads to one pad wearing out much faster than the other.
- Vibration: While often caused by warped rotors, loose or failing hardware can also contribute to a pulsating or vibrating feeling in the brake pedal.
- Sticking Brakes: Corroded caliper guide pins or clips can prevent the brake pads from retracting from the rotor. This causes a dragging sensation, can lead to overheating, and will rapidly wear down your pads and rotors.
Known Issue: Front Brake Squeal TSB
Lexus issued a Technical Service Bulletin (TSB) L-SB-0008-22 for some 2019 ES350 models that may exhibit a squeal or squeak from the front brakes. The bulletin notes that an updated fitting kit (hardware kit) is available to resolve the issue for customers who find the noise objectionable. If your 2019 model is experiencing this, using a high-quality aftermarket or OEM hardware kit is the solution.
Choosing the Right Aftermarket Hardware Kit
For a part like a brake hardware kit, the difference between OEM and a quality aftermarket brand is often minimal, especially since many aftermarket companies are also OEM suppliers. The key is to avoid the cheapest, no-name options and stick with reputable brands known for good fitment and materials.
| Brand | Tier | Notes |
|---|---|---|
| Beck Arnley | Excellent | Specializes in import vehicles and often sources parts from the same manufacturers that Lexus uses. A very reliable choice. |
| Centric / Dynamic Friction (DFC) | Excellent | Centric is a well-regarded brand in the aftermarket, known for quality that often meets or exceeds OEM standards. DFC is noted for using high-quality stainless steel components. |
| Raybestos | Good | A long-standing, reputable brand in the brake industry. Their professional-grade line is a solid choice for reliability and performance. |
| Dorman | Standard | Dorman provides a wide range of parts and is generally a reliable, budget-friendly option. While quality can vary on complex parts, their brake hardware is typically a safe bet. |
Pro Tip: Many high-quality brake pad sets include a new hardware kit in the box. Check the product description before buying a separate kit to avoid purchasing parts you don't need.
Cost of Replacing Brake Hardware on a 2014-2019 Lexus ES350
The hardware kit itself is inexpensive. However, since the labor is the same as a full brake job, it is almost always replaced along with the pads and rotors. The costs below reflect this common scenario.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Hardware Kit | $9.35 - $59.59 |
| Shop Labor (as part of a brake job) | $150 - $250 per axle |
| Complete Aftermarket Brake Job (Pads, Rotors, Hardware) | $400 - $600 per axle |
| Complete OEM Brake Job at Dealer (Pads, Rotors, Hardware) | $600 - $1000+ per axle |
Frequently Asked Questions (FAQ)
Do I really need to replace the brake hardware?
Yes. It is highly recommended. The small metal clips and springs lose their tension over time due to thousands of heating and cooling cycles. Reusing old hardware can lead to noise, premature pad wear, and other braking issues, negating the savings of a few dollars.
Can I install just the hardware kit myself?
Yes, if you are comfortable performing a brake job. Replacing the hardware requires removing the wheel and the brake caliper, the same first steps as replacing the pads. 🎬 Watch this step-by-step guide on replacing your front brake pads. The difficulty is low-to-moderate for a DIYer with the right tools.
Is there a recall on the 2014-2019 ES350 for brake hardware?
No, there are no specific recalls for the disc brake hardware kit. There was a recall for some 2019 models related to the brake booster pump and another for 2016 models for an ABS actuator, but neither involves the hardware clips and springs directly.
What's the difference between front and rear hardware kits?
Front and rear brake hardware kits are not interchangeable. The front and rear brake calipers on your ES350 are different sizes and designs, so they require specific hardware. Always ensure you are purchasing the correct kit for the axle you are working on.
