description

This brake friction disc uses carbon steel base with friction lining, serving as core component of wet multi-disc brake. It creates braking torque against steel plates under hydraulic clamping for heavy-duty mining continuous braking. Excessive lining wear, heat burn, warpage and spline crack will lead to weak braking, slip, long stopping distance, noise and overheating, even brake failure.

Fits Caterpillar 789B,789C,789D,789G mining dump truck, for overhaul of wheel wet brake assembly.

FAQ 

Q：Can I replace only one partially worn disc while others are intact?
A：Not recommended. Uneven wear causes unbalanced brake load, slip and overheating.

Q：Can lightly burnt disc be reused after surface grinding?
A：Not recommended. High temperature damages friction material and reduces braking coefficient.

Q：Will new friction discs fix the issue if brake oil contains metal powder?
A：No. Debris scratches disc and steel plates, flush brake cavity and change oil fully.

Q：What risk exists if spline has minor burrs?
A：It causes disc binding and wobble, uneven load and accelerated wear or sticking brake.
