It's important to note that these pads are generally not recommended for street use due as they can be noisy, produce significant dust, and may require higher operating temperatures to perform optimally.
The Unsung Hero: Brake Shims and Their Vital Role
While the focus is often on the brake pads themselves, another crucial component often overlooked is the brake shims. These thin, precisely engineered plates sit between the back of the brake pad and the caliper piston.
Why are Shims Essential? Eliminating Brake Squeal
The primary function of brake shims is to eliminate brake noise, particularly the dreaded squeal. Brake squeal is typically caused by high-frequency vibrations that occur when the brake pad vibrates against the caliper or piston during braking. These vibrations resonate, creating an irritating metallic screeching sound.
Brake shims work by acting as a dampener or absorber for these vibrations. They are often constructed with multiple layers of different materials, such as steel, rubber, or composites. This multi-layer design helps to dissipate the vibrational energy before it can amplify into an audible squeal. They also ensure a snug fit for the pad within the caliper, further reducing movement and potential noise.
Mitsubishi OEM Front + Rear Brake Shims COMBO - EVO 8/9/X Example
The importance of shims is highlighted by specific applications, such as the Mitsubishi OEM Front + Rear Brake Shims COMBO for the EVO 8/9/X. As the product description states: "When replacing your brake pads it is wise to replace the brake shims at the same time. Shims go between the pad and the caliper to help eliminate squeal (brake squeal is caused by the pad vibrating on the pad). The shims help stop or absorb the vibration."
For high-performance vehicles like the Mitsubishi EVO, which are often driven hard and benefit from precise braking, ensuring every component contributes to optimal function is paramount. Replacing shims simultaneously with pads ensures that the new pads operate in the quietest, most efficient manner possible from day one, preventing premature noise issues that can arise from worn or damaged old shims.
The Synergy of Pads and Shims: A Complete Braking Solution
For the best possible braking performance and user experience, a holistic approach is essential. Investing in high-performance StopTech brake pads without addressing the condition of your brake shims is akin to putting premium fuel in a car with a clogged fuel filter. The full potential simply won't be realised.
When you install new StopTech pads, especially those designed for high performance, pairing them with new, quality brake shims ensures that the entire braking assembly works in harmony. This combination delivers not only the superior stopping power and fade resistance that StopTech is known for but also the quiet, smooth operation that enhances driving comfort and confidence.
Installation and Bedding-In: Maximising Performance
While installing brake pads and shims might seem straightforward, professional installation is always recommended to ensure proper fitment and safety. However, one crucial step that applies to all new brake pads, especially performance-oriented ones like StopTech, is the bedding-in process.
The Bedding-In Process
Bedding-in, also known as 'burnishing', is a critical procedure that prepares new brake pads and rotors for optimal performance. It involves a series of controlled stops that gradually bring the brakes up to temperature. This process achieves two main goals:
- It transfers a thin, even layer of friction material from the new pads onto the rotor surface. This 'transfer layer' is essential for consistent friction and effective braking.
- It helps to cure the resins within the brake pad compound, making the pad material more robust and resistant to heat.
Failing to properly bed-in your new brakes can lead to reduced performance, inconsistent braking, increased noise, and premature wear. Always follow StopTech's specific bedding-in recommendations, which typically involve a series of moderate and then harder stops from varying speeds, allowing the brakes to cool between cycles.
Maintaining Your Braking System for Longevity and Safety
Even with top-tier components like StopTech pads and new shims, regular maintenance is key to ensuring your braking system remains in peak condition. Regular inspections should include checking:
- Pad Wear: Monitor the thickness of your brake pads. Most pads have wear indicators, but a visual check is always prudent.
- Rotor Condition: Look for signs of excessive wear, scoring, cracks, or warping on your brake discs.
- Brake Fluid Levels and Condition: Ensure the fluid is at the correct level and isn't discoloured. Brake fluid should be changed periodically as it absorbs moisture over time.
- Caliper Function: Check for any signs of seized pistons or leaks, which can impair braking performance.
Adhering to your vehicle's service schedule and addressing any braking anomalies promptly will not only extend the life of your components but, most importantly, safeguard your driving safety.
