Brake Lining Friction Assessment Test Machine

Chase-type friction machine that measures friction coefficient and wear of brake linings and clutch facings against a rotating drum under controlled temperature. Used by friction material makers and brake pad QC labs.

Specification

Brake lining specimens are pressed against a heated rotating drum while torque and temperature are logged to compute normal and hot friction coefficients. The software plots friction against temperature through the heat-up, fade and recovery sequence and calculates wear by thickness and weight loss.

Features

• Cast iron drum with embedded thermocouple for temperature control
• Dead-weight or pneumatic specimen loading at 0.69 MPa
• Torque arm with load cell for friction coefficient
• Programmable fade and recovery test sequence
• PC software with friction versus temperature graph
