Brake Pad Pressure Distribution

Measure, view, and evaluate dynamic forces acting between a brake pad and rotor or brake shoe and drum.

Evaluate Brake Pad Pressure Distribution

The I-Scan^® force and pressure measurement system is a versatile research and development tool for brake system and friction plate manufacturers. The system can provide instant insight into the dynamic forces and pressures acting between a brake pad and rotor or brake shoe and drum. The I-Scan system clearly shows where uneven pressures exist between these mating surfaces, predicting wear and stress on the pad. This information can be used to address the challenges facing brake design engineers, such as reducing brake noise, vibration, and harshness through design improvements.

Tekcan’s patented, thin-film sensors are available in different shapes, are reusable, and provide accurate pressure readings. With the help of our highly qualified sales and engineering support team, each system may be configured to meet your specific needs.
