A Guide to the Disc Brake Hardware Kit for the 2020-2025 Lexus ES350
Eliminate brake noise and promote even pad wear by replacing these critical components during your next brake service.
- Always replace brake hardware when changing brake pads to prevent noise and ensure even wear.
- A known TSB for front brake squeal on 2019-2022 models is fixed by installing an updated hardware kit.
- Aftermarket brands like Beck Arnley, Raybestos, and Dynamic Friction offer reliable, cost-effective alternatives to OEM hardware.
- The rear brakes have an Electronic Parking Brake (EPB) that must be put in 'Service Mode' before replacement.
Symptoms of Failing Brake Hardware
Worn or corroded brake hardware can cause problems that you might mistake for bad brake pads or rotors. Because it's inexpensive, replacing the hardware with every brake pad change is a smart move to keep your Lexus braking system working like new.
- Brake Noise: Rattling or clicking sounds, especially over bumps, can happen when loose or weak clips fail to hold the pads tightly. A persistent squeal, even with new pads, can also point to hardware issues.
- Uneven Brake Pad Wear: If the clips are rusted or bent, the brake pads can get stuck. This causes them to drag on the rotor, leading to one pad wearing out much faster than the other.
- Vibration: While less common, hardware that causes a pad to sit at an angle can contribute to vibrations during braking.
Known Issue: Front Brake Squeal TSB
Lexus released Technical Service Bulletin (TSB) L-SB-0008-22 for 2019-2022 ES350 models that may have a squeaking or squealing noise from the front brakes. The official fix is to install an updated front brake fitting kit, which is the brake hardware. This shows that even from the factory, the right hardware is critical for quiet operation. Using a quality new aftermarket kit during a brake job can prevent this specific problem.
Choosing the Right Aftermarket Hardware Kit
For your 2020-2025 ES350, the original equipment (OEM) hardware is excellent, but aftermarket brands offer comparable quality, often for less money. The key is to choose a kit from a reputable manufacturer. All the brands listed provide the necessary components to restore proper brake function.
Brand Quality Tiers:
- Beck Arnley: Often considered a premium aftermarket brand. They are known for sourcing parts that meet or exceed OEM specifications, and sometimes even use the same suppliers as Lexus. This is a strong choice if you want as close to original quality as possible.
- Raybestos: A very well-known and respected name in the brake industry. Raybestos parts are a reliable standard for daily driving, providing performance and durability equivalent to the original parts. They are a go-to for many professional mechanics.
- Dynamic Friction: This brand has built a reputation for good quality and value. Their hardware kits are a solid choice for an OE-style replacement and are trusted for daily use.
Pro Tip: Always choose hardware kits made from stainless steel. Stainless steel resists rust and corrosion much better than regular steel, which is important for parts constantly exposed to heat, water, and road salt. This ensures the hardware lasts longer and the brake pads continue to move freely.

Frequently Asked Questions (FAQ)
Do I have to replace the hardware with every brake job?
Yes, it is highly recommended. The old clips lose their spring tension from thousands of heating and cooling cycles. Reusing them can lead to noise and improper pad movement. Since the kits are inexpensive, it's cheap insurance for a quiet, effective brake job.
What is included in a typical disc brake hardware kit?
A kit for your ES350 will typically include all the necessary anti-rattle clips (also called abutment clips) and springs for two wheels (either both front or both rear). These are the metal pieces the brake pads rest on and slide against.
Is there a difference between front and rear hardware kits?
Yes, the front and rear brake calipers on your ES350 are different sizes and use different hardware. You must buy the correct kit for the axle you are working on. The parts are not interchangeable.
What is the Electronic Parking Brake (EPB) Service Mode?
Your 2020-2025 ES350 has an Electronic Parking Brake (EPB) on the rear wheels. You cannot simply push the rear caliper piston back to install new pads. You must first put the system into a special 'Service Mode' using a sequence of button presses or a diagnostic scan tool. Failing to do this will damage the expensive rear calipers.
