A Mechanic's Guide to the Best Brake Pads for the 2017-2025 Lexus RX350
Stop wasting money at the dealership; here’s how to choose the right brake pads for your Lexus RX350.
- The original brake pads are made by Advics or Akebono; buying these brands is like getting OEM quality without the dealer markup.
- Rear brake pad replacement is complicated by an Electronic Parking Brake (EPB) that requires a special procedure or tool to retract.
- For quiet, low-dust performance similar to stock, choose ceramic pads from brands like Akebono, Advics, or Bosch.
- Some 2017 models were recalled for a faulty brake booster vacuum pump; confirm this was addressed on your vehicle.
Symptoms of Worn Brake Pads on an RX350
Your Lexus is designed to tell you when its brake pads are getting low. Don't ignore these signs, as worn pads can lead to more expensive repairs.
- Squealing or Screeching: Most brake pads have a small metal tab called a wear indicator. When the pad material wears down, this tab scrapes against the rotor, making a high-pitched noise to alert you.
- Grinding Noise: If you hear a deep, metallic grinding, stop driving as soon as it is safe. This means the pad material is completely gone, and the metal backing plate is grinding against the rotor, causing serious damage.
- Vibration or Pulsing: If you feel a pulsing in the brake pedal or steering wheel when you brake, it could be a sign of warped rotors, often caused by worn-out pads.
- Longer Stopping Distances: If you notice your RX350 is taking longer to stop than it used to, your brake pads may be too worn to create effective friction.
Important Recall Information for 2017 Models
There was a safety recall for some 2017 Lexus RX350 vehicles related to a faulty brake booster vacuum pump (NHTSA Campaign ID: 18V211000). This could cause a sudden loss of braking assistance. This is not a brake pad issue, but a critical safety problem. Verify with a Lexus dealer if your vehicle was affected and if the recall work has been completed.
Choosing the Right Aftermarket Brake Pads
You don't have to buy brake pads from the Lexus dealer to get great performance. The original pads on your RX350 were likely made by Advics or Akebono. You can buy these same brands in the aftermarket for less money.
Tier 1: OEM-Equivalent Brands
These pads are made by the same companies that supply Lexus. They provide the same quiet, smooth, low-dust performance you expect from your vehicle.
- Advics: As an original equipment supplier, Advics pads are a direct replacement for what came on your RX350 from the factory.
- Akebono: Known for their ProACT ceramic pads, Akebono is another OEM supplier and a favorite among Lexus owners for their quiet operation and low dust.
Tier 2: Premium Aftermarket Brands
These brands offer excellent quality that meets or exceeds OEM standards. They are trusted names in the industry and a great choice for your RX350.
- Bosch: Their Blue and QuietCast lines are well-regarded for being quiet and reliable.
- Wagner Brakes: The Wagner OEX and ThermoQuiet lines are popular for their durability and consistent stopping power.
- Raybestos: The Element3 line offers a great combination of performance and value.
- Brembo: While famous for performance, their standard replacement ceramic pads are a high-quality option for daily driving.
Tier 3: Performance Brands
If you want more initial "bite" or improved fade resistance for towing or spirited driving, these brands are for you. Be aware they may produce more dust and noise than OEM pads.
- Hawk Performance: Offers various compounds from street performance to track-focused pads.
- EBC Brakes: Their Greenstuff and Redstuff pads are popular choices for a noticeable upgrade in stopping power.
- PowerStop: Often sold in kits with rotors, PowerStop offers a good balance of performance and daily usability.
Tier 4: Economy Brands
These pads meet basic safety standards and are very budget-friendly. They are a good choice if cost is your primary concern, but they may not offer the same quietness, low-dust performance, or longevity as premium options.
- Centric / C-Tek
- Dynamic Friction
- Pronto
Critical Information for DIY Rear Brake Replacement
Your 2017-2025 Lexus RX350 has an Electronic Parking Brake (EPB). You CANNOT simply push the rear caliper piston back in. You must put the system into 'Service Mode' first.
- For 2020-2025 Models: You can typically enter service mode using a sequence of steps involving the brake pedal and the EPB switch inside the car.
- For 2017-2019 Models: The button sequence does NOT work. You MUST use a bidirectional scan tool or a separate 12V battery to electronically retract the parking brake motor on the caliper. Attempting to force the piston back will damage the caliper.
Front brake pad replacement is straightforward and does not involve the EPB system.
Frequently Asked Questions (FAQ)
What's the difference between ceramic and semi-metallic pads?
Your Lexus RX350 came with ceramic brake pads from the factory. Ceramic pads are known for being very quiet, producing little dust, and offering smooth, consistent stopping. Semi-metallic pads can offer better performance in extreme heat and have a stronger initial bite, but they are often noisier and create more black dust that dirties your wheels.
Do I need to replace my rotors at the same time as my pads?
Not always, but it's highly recommended. A new, flat rotor surface allows the new pads to bed-in properly, ensuring smooth, quiet braking and maximum performance. If your current rotors are thin, grooved, or vibrating, they must be replaced. Installing new pads on worn rotors is a common cause of noise and reduced performance.
Why are my new brakes squeaking?
New brake squeal is often caused by high-frequency vibrations. Common causes include not replacing old hardware (shims and clips), not cleaning and lubricating the caliper slide pins, or not applying brake grease to the back of the pads. Sometimes, new pads simply need a 'bedding-in' period to properly mate with the rotors. Some Lexus models have had Technical Service Bulletins (TSBs) for brake squeal, with the fix being an updated shim kit.
What does it cost to replace brake pads on an RX350?
Costs vary widely. At a dealership, you could be quoted over $700 for one axle. An independent shop is more likely to be in the $330-$400 range per axle, including parts and labor. If you do it yourself, a set of high-quality aftermarket pads will cost between $40 and $150.
