Disk Brake Wear Analysis

Driven by Automotive Manufacturers, Disc Braking Systems Suppliers and Testing Laboratories in the US, Europe and Asia, Capacitec has developed a new line of specialized non-contact capacitive Disk Brake dimensional analysis sensors. The new model HPC-150C-H-IC-00 sensor assembly combines the benefits of small size and high temperature 750°F (400°C) operation.

Another major advantage of the new configuration is lower sensor replacement cost. The redesigned sensor surface provides enhanced "impact survivability". In addition, an innovative new integral connector, located behind the sensing surface, allows easy replacement of coaxial extension cables without the added cost of replacing the sensors themselves.

This new sensor system is capable of taking dynamic brake system measurements both on-vehicle at test track facilities as well as in testing laboratories using dynomometers. For higher temperature dynomometer testing Model V Series 1,600°F (871°C ) displacement probes and cables are available. By measuring the displacement data on a brake rotor in motion, measurements can be collected and analyzed to show the following characteristics:

Rotor run-out (TIR), Thermal expansion

Rotor coning, Wobble

Rotor thickness variation (RTV)

Dyanamic thickness variation (DTV)

Plate-to-plate orientation (V-ing, barreling)
