There’s a specific sound that grates on the nerves of any driver: the high-pitched squeal of worn-out brakes. It’s a sound that announces your arrival from a block away, turning heads for all the wrong reasons. For weeks, that was the soundtrack of my daily commute in our family’s trusted 2016 Toyota RAV4. Every gentle press of the pedal at a stoplight was met with an embarrassing screech from the rear driver’s side. We’d tried the usual fixes—new pads, cleaning and re-lubricating the caliper pins—but the noise always returned, a persistent ghost in the machine. It became clear that the original rotors, after years of service, were the likely culprits. This is a common story for millions of vehicle owners. You don’t need a high-performance racing setup; you just need your car to stop safely, quietly, and reliably, just like it did the day it left the showroom. The search for an affordable, all-in-one solution led us directly to the Power Stop KOE4671 Brake Kit Replacement Rotors and Pads, a kit promising an OE-quality restoration without the dealership price tag.

- Z17 Stock Replacement brake kit is recommended for drivers looking to refresh their daily driven vehicle's stopping power back to OE, stock performance
What to Consider Before Buying a Replacement Brake Kit
A brake kit is more than just a set of replacement parts; it’s a critical safety system for your vehicle. It’s the key solution for restoring lost braking performance, eliminating noise, and ensuring you and your passengers can rely on your car’s ability to stop on a dime. The primary benefits of opting for a complete kit are convenience and compatibility. Instead of hunting down rotors from one brand and pads from another, a kit like this ensures all components are engineered to work together seamlessly, taking the guesswork out of a crucial repair.
The ideal customer for this type of product is the daily driver, the DIY home mechanic, or the budget-conscious vehicle owner facing worn-out brakes on a compatible Toyota RAV4 or Lexus HS250h. This kit is designed for those who want to restore their vehicle’s original, factory-level stopping power and quiet operation. It’s a refresh, not a revolution. On the other hand, it might not be suitable for those who engage in performance driving, frequent towing, or live in mountainous areas where enhanced heat dissipation from drilled or slotted rotors would be beneficial. For those users, a more aggressive “Truck & Tow” or “Performance” level kit would be a more appropriate, albeit more expensive, alternative.
Before investing, consider these crucial points in detail:
- Vehicle Compatibility & Fitment: This is the most important factor. An incorrect kit is useless. Always double-check that the kit’s part number (in this case, KOE4671) is specified for your vehicle’s exact year, make, and model. Using your vehicle’s VIN to confirm fitment with the manufacturer or seller is the safest bet to avoid costly mistakes and installation headaches.
- Performance Level (OE vs. Upgrade): Understand what you’re buying. The Power Stop KOE4671 Brake Kit Replacement Rotors and Pads is an Autospecialty OE (Original Equipment) replacement. This means it’s designed to meet or slightly exceed the performance of the parts your car came with. It is not a performance upgrade; the rotors are solid, not drilled or slotted, which is perfectly adequate for 99% of daily driving conditions.
- Materials & Durability: This kit features Z17 Evolution ceramic brake pads, which are an excellent choice for daily drivers due to their low-dust and low-noise characteristics compared to semi-metallic pads. The rotors are standard cast iron. A key point to note, and one we’ll explore in-depth, is that these rotors are uncoated, which means they are susceptible to cosmetic surface rust on non-contact areas.
- Ease of Installation & Inclusions: One of the biggest advantages of a kit is getting everything you need in one box. This kit includes the rotors, pads, and all-new stainless steel hardware like shims and clips, plus a packet of high-temperature lubricant. For a DIYer, this is a massive convenience that prevents a last-minute trip to the auto parts store.
Keeping these factors in mind, the Power Stop KOE4671 Brake Kit Replacement Rotors and Pads stands out in several areas, particularly for its value and completeness. You can explore its detailed specifications and confirm vehicle fitment here.

First Impressions: Unboxing a Complete and Convenient Solution
The arrival of the Power Stop KOE4671 Brake Kit Replacement Rotors and Pads was met with a sense of relief. The box itself is substantial, weighing in at just over 23 pounds, which immediately gives you confidence in the solidity of the components inside. Opening it up, we were greeted with a well-packaged and thoughtfully organized kit. There were no frills, just business. The two Autospecialty OE replacement rotors were hefty and precisely machined, with a non-directional surface finish ready for break-in. Nestled beside them was the set of Z17 Evolution ceramic brake pads, complete with factory-installed shims to help dampen noise.
What truly impressed us, however, were the small but crucial details. Power Stop includes a complete set of new stainless steel installation hardware and a small packet of ceramic brake lubricant. Any mechanic, professional or amateur, knows that re-using old, rusted clips and pins is a recipe for noise and improper function. Including fresh hardware in the box elevates this from a simple parts package to a true, comprehensive repair kit, saving time and ensuring the job is done right the first time. It’s a thoughtful touch that demonstrates an understanding of the end-user’s needs.
What We Like
- Comprehensive kit includes rotors, pads, hardware, and lubricant
- Excellent value compared to purchasing parts individually from auto stores
- Z17 ceramic pads offer quiet, low-dust performance ideal for daily driving
- Direct bolt-on design ensures a perfect OE fit for compatible vehicles
What We Didn’t Like
- Rotors are uncoated and will develop cosmetic surface rust quickly
- Strictly an OE replacement, not a performance upgrade for demanding conditions
Putting the Power Stop KOE4671 to the Test: From Garage to Gridlock
A box of promising parts is one thing; real-world performance is what truly matters. We installed the Power Stop KOE4671 Brake Kit Replacement Rotors and Pads on our 2016 Toyota RAV4 to see if it could finally silence the squeal and restore the confident braking we remembered. The process, from installation to daily driving evaluation, revealed the true character of this popular brake kit.
Installation Experience: A Straightforward and Rewarding DIY Project
For anyone with a decent set of tools and a bit of mechanical inclination, installing this kit is a thoroughly manageable weekend project. The entire process was refreshingly straightforward. We started by safely jacking up the rear of the vehicle and removing the wheels. The old caliper, rotor, and pads came off without much of a fight. The true test of any replacement part is fitment, and this is where the Power Stop kit shined. The new Autospecialty rotor slid perfectly onto the hub, lining up exactly with the caliper bracket. There was no need for modification, grinding, or frustration. This is a testament to Power Stop’s engineering and quality control.
The included hardware was a game-changer. We discarded the old, grimy clips and installed the fresh stainless steel pieces, which snapped cleanly into place on the caliper bracket. Using the supplied high-temperature lubricant on the pad ears and contact points is a critical step to prevent future noise, and having it included meant we didn’t have to second-guess what product to use. The Z17 pads dropped into the new clips smoothly, and the caliper bolted back into place over the new rotor without any issue. This seamless experience confirmed what one user noted: this kit “made it so easy.” The perfect fit and all-inclusive nature transformed a potentially frustrating repair into a satisfying and successful job.
On-the-Road Performance: Restoring Factory-Fresh Braking Feel
With the new hardware installed, the next crucial step was the break-in, or “bedding,” procedure. This involves a series of moderate-to-aggressive stops to deposit an even layer of friction material from the pads onto the rotors. This process is vital for noise-free performance and optimal stopping power. We followed Power Stop’s clear instructions, and after the components cooled, we took the RAV4 out for its first real test drive in city traffic.
The difference was immediate and profound. The annoying, high-pitched squeal that had plagued us for months was completely gone. In its place was silent, smooth, and confident braking. The pedal feel was firm and responsive, mirroring the performance of the vehicle when it was new. In stop-and-go traffic and during highway deceleration, the Power Stop KOE4671 Brake Kit Replacement Rotors and Pads performed flawlessly. Some users have commented that they didn’t feel a “brand new” difference, but it’s important to set the right expectation. This is an OE replacement kit. Its goal is to restore original performance, not to provide the aggressive bite of a track-ready setup. For a daily driver like our RAV4, it achieved that goal perfectly, delivering predictable and safe stopping power for a fraction of the cost of OEM parts from a dealership.
The Durability Question: Confronting the Inevitable Rust Issue
No review of this kit would be honest without directly addressing the most common complaint we found in user feedback: rust. Several users reported seeing rust on the rotors within weeks, and our experience confirmed this. After the first rainstorm, a thin layer of orange surface rust appeared on the rotor hat (the central, non-contact part) and the internal cooling vanes. This is entirely expected. These are standard, uncoated cast iron rotors. Unless they are treated with a protective coating like zinc plating, any exposure to moisture will cause cosmetic surface rust. This is a visual issue, not a performance one.
It’s crucial to understand that this rust does not impact braking safety or effectiveness. The brake pads sweep the contact surface of the rotor clean with every stop, preventing any rust buildup where it matters. As one user astutely pointed out, their original OEM rotors rusted in the same way. Power Stop’s own customer service confirmed that only their higher-end drilled and slotted rotors receive a zinc-plated anti-rust coating. Therefore, buyers of the KOE4671 kit should expect this cosmetic rusting as a trade-off for the kit’s exceptional value. If a pristine, rust-free look behind your wheels is a top priority, you would need to invest in a more expensive, coated rotor kit. For those prioritizing function and budget, the cosmetic rust is a minor and predictable compromise.
What Other Users Are Saying
Our findings align closely with the collective experience of other drivers. The feedback landscape for the Power Stop KOE4671 Brake Kit Replacement Rotors and Pads is largely positive, focusing on value and problem-solving. One user, driving a 2016 RAV4 just like our test vehicle, echoed our experience perfectly. They had battled a persistent squeal for years, trying various fixes, and this kit was the final, successful solution. They specifically highlighted the value, noting that a similar set of parts from a local auto parts store would have cost nearly three times as much.
On the other hand, the negative feedback is almost singularly focused on the rust issue. One user expressed disappointment that the rotors “got rusted in a week,” looking much older than they were. Another confirmed after contacting the company that these specific rotors are not treated against rust. This feedback is valid and important, but it reinforces our conclusion: this is a known characteristic of an uncoated, entry-level OE replacement kit. It’s a compromise for the price, and customers should be aware of it before purchasing.
