NU-LOK PISTON CUSHION
Attacks a known NVH problem area
Using the same technology as a NU-LOK shim, the PISTON CUSHION is designed to attack a known NVH problem area, the caliper, pad and rotor interface, reducing noise levels and eliminating comebacks.

Nu-Lok Piston Cushion benefits
As a mechanic or garage owner, NVH and heat are your enemies. Brake noise, vibration, harshness and excessive heat build-up are the leading causes of frustration for you and your customers.
- Absorbs piston vibrations for improved NVH
- Universal system for improved noise abatement
- Minimum cost to address comebacks
- Kit-based distribution to the installer
- Easy installation
- Heat shield across pad, rotor and caliper
- Protective cap for the piston, reducing wear and heat impact on pistons
Performance test result
To measure noisy brake stops and NVH, the PISTON CUSHION was put through many tests, including the SAE standard J2521 noise test. This is the automotive industry standard test. It consists of 1,430 stops at various pressures, velocities and temperatures. A noisy stop is considered any stop having a greater than 70dB noise rating.
The chart shows two comparative SAE J2521 noise tests for a brake application. The test was run once without NU-LOK Piston Cushion and again with it. In each case, the number of noisy stops was tracked and charted. After 1,430 stops, NU-LOK Piston Cushion reduced the number of noisy stops by over 70%.
Heat and brake fade
When brakes are applied to a moving vehicle, heat is created through the friction between the brake pads and rotors. Heat transfer happens when the heat travels through the brake caliper to affect other parts of the braking system, like the brake fluid. NU-LOK Piston Cushion acts as a barrier, minimizing heat transfer to the brake fluid.
After 1,430 stops, NU-LOK Piston Cushion reduced the number of noisy stops by over 70%.
