Raybestos Element3: Enhanced Stopping & Silence

The Raybestos Element3 series is notable for its hybrid technology, which combines the best traits of ceramic and semi-metallic friction materials. This allows the pads to deliver both superior stopping power and the quiet operation that homeowners prioritize.

The shims included with these pads are multi-layered, providing a robust barrier against the metal-on-metal contact that generates unwanted noise. For those who prioritize safety and are wary of the “fading” feeling some brakes experience after heavy use, this hybrid approach provides a noticeable difference.

Ultimately, Element3 pads are an excellent choice for drivers who want a premium feel without sacrificing the longevity of their rotors. They bridge the gap between performance racing components and standard commuter pads, making them a versatile selection for most mid-sized sedans.

Bendix CQ Ceramic: Dependable, Noise-Free Stops

Bendix is a legendary name in the automotive world, and their CQ (Convenient Quality) line brings that heritage to the average garage. These ceramic pads are designed specifically to provide a consistent, fade-free experience throughout the entire life of the pad.

The shims on these units are meticulously fitted to reduce vibration, ensuring that the driver never hears a whistle or squeak when pulling into the driveway. They are particularly well-suited for older vehicles that might be more prone to brake noise as components begin to age and settle.

Choosing Bendix CQ is a vote for stability and predictability. For the homeowner who wants to perform a brake job once and move on to the next project, these pads offer the peace of mind that comes with a well-established brand.

ACDelco Gold: The Go-To for GM Vehicle Owners

For households operating Chevrolet, GMC, or Buick vehicles, ACDelco Gold is often the gold standard for restoring factory performance. These components are designed to meet the exact specifications of original equipment, ensuring a perfect fit every single time.

Because they are precision-engineered for specific vehicle platforms, the shim interface is seamless and highly effective at noise suppression. Using these pads removes the guesswork associated with “universal” fitment pads that may lead to rattling or uneven wear over time.

Centric Posi Quiet: An Affordable Quiet Upgrade

Not every brake repair requires high-performance pricing, and Centric Posi Quiet pads prove that value and silence can coexist. These pads are finished with a scorched process that helps to seat them quickly, meaning the noise reduction begins from the very first mile.

The shims included with this line are specifically designed to reduce noise on older or high-mileage vehicles where the brake calipers might have slightly more play. This makes them a favorite for budget-conscious families managing older sedans or teen drivers’ vehicles.

The bottom line is that Posi Quiet offers a tremendous bang for the buck. They provide a noticeable improvement over standard economy pads, making them the ideal choice for those who need a reliable, quiet solution without breaking the household budget.

Shim Materials: Rubber, Metal, or Multi-Layer?

Understanding shim materials is key to solving persistent squeaks, as the material determines how well energy is dampened. Rubber-coated metal shims are excellent for flexibility and creating a tight seal against the caliper, while multi-layer steel shims use thin gaps to break up sound vibrations.

Simple metal shims are often found on budget pads and, while effective at first, can degrade more quickly under high heat. In contrast, multi-layer designs act as an acoustic barrier, absorbing the resonance that causes that high-pitched “chirp” during low-speed stops.

When shopping, prioritize multi-layer shims if the vehicle is prone to noise or if the driving environment includes frequent stop-and-go traffic. A superior shim material can often compensate for a slightly lower-tier pad, making it the most important “hidden” feature to check before a purchase.

The Right Way to Apply Brake Grease to Your Shims

Even the highest-quality shims require a small amount of assistance to perform at their absolute best. Applying a thin layer of high-temperature brake grease—specifically a synthetic, silicone-based lubricant—to the back of the shim and the contact points is essential.

Avoid the mistake of applying too much grease, as excess lubricant can migrate onto the rotor surface, which drastically reduces braking efficiency and compromises safety. Only a light, even film is necessary to act as a vibration-dampening cushion between the shim and the caliper piston.

Always clean the metal contact surfaces with a wire brush before applying fresh grease to ensure a smooth, debris-free application. This small, five-minute step is often the difference between a silent brake job and one that develops a squeak within a few weeks.

Should You Reuse Old Shims? A Common Question

It is a common temptation to reuse old shims when swapping in new pads to save a few dollars or a trip to the store. However, shims lose their tension and dampen properties over time, meaning they are rarely capable of providing the same level of noise suppression as a fresh set.

Reusing old, fatigued shims often leads to the exact problem a new brake job is meant to solve: annoying brake squeal. Most modern premium brake pad kits include new shims in the box, and using them is an essential part of the installation process.

If the new pads do not include shims, or if the current ones appear rusted or deformed, always replace them with new, compatible hardware. Investing a few extra dollars in fresh hardware is the most reliable way to ensure the new pads perform silently and effectively for their entire lifespan.

A quiet braking system is essential for maintaining the comfort and reliability of the family vehicle. By choosing the right pads and taking the time to install shims correctly, these common noises can be eliminated for good, allowing the household to focus on the road ahead rather than the maintenance behind.
