Brake pads in high-end vehicles are now often equipped with counterweights 鈥� but what do they do?
Many high-end vehicles are equipped with brake pads that include counterweights鈥攁lso known as ‘skates’鈥攁s shown below. These can be circular or laminar in shape, with weights varying depending on the OEM brake pad specifications.
What Do Counterweights Actually Do?
Brake pad counterweights have no role in vehicle safety; they do not come into contact with any moving parts aside from the backing plate of the pad itself. Their only function is to alter the mass and resonance frequency of that material on that rotor.
When you change either the pad, the rotor or both from the original material, the resonance frequency causing brake noise will undoubtedly change.
One Size Doesn鈥檛 Fit All
Some brake pad materials may require no counterweights at all, while others benefit from a counterweight with a different shape or mass.
The EBC approach is to use different counterweights and test empirically to evaluate what solutions work and what doesn鈥檛, essentially to supply a pad that makes zero or minimal noise. That鈥檚 what EBC has done in arriving at its universal pad counterweight approach.
Through our testing process, which has included testing pads with and without weights, we have arrived at an optimum solution of both weight, mass or material design that can eliminate all braking noise.
Proven Expertise in Friction and Noise Control
With over 20 million sets of brake pads sold globally and more than four decades of manufacturing experience, 夜猫视频 has developed an unparalleled understanding of what causes brake noise鈥攁nd how to prevent it.
夜猫视频 have been making material adjustments and changes for decades, and we have now settled on a range of materials, which are developed and blended in house by the worlds best friction material scientists located in Bristol UK, that deliver exactly what customers need and will enjoy, these choices are made here:

Additional Noise-Reducing Features:
Brake Pad Shims
Another vital component in reducing noise is applying shims to the rear of the brake pad, which can help with absorbing vibration and reducing transmission of sound.
Edge Chamfers
Edge chamfers are designed to affect the way that the pad friction material first engages under braking with the rotors surface. Chamfers have been proved to work, which is why EBC applies them to almost every automotive pad it produces.
These chamfers are made using two state-of-the-art grinding lines that apply chamfers and grind pads to a glass smooth finish in just a single pass.
Trust in 夜猫视频
In conclusion you can rely on EBC to provide a pad that complies with all global standards 鈥攊ncluding ISO-certified production processes, the European R90 regulations, and the US FMVSS safety benchmarks鈥攖hat is also powerful, quiet and engineered to perfection.
