Question: 1 / 1030

Which type of brake is not adaptable to mechanical operation?

Disk brake type

Drum brake type

Expander tube type

The Expander tube type brake is not adaptable to mechanical operation because it relies on hydraulic pressure to operate. The other three types of brakes listed (disk brake, drum brake, and S-cam type) can all be operated mechanically by using cables, levers, or other mechanical systems. This makes them more versatile and suitable for a wider range of vehicles and situations. Expander tube brakes are typically used in heavy-duty trucks and trailers and require specialized hydraulic systems to function properly, making them less adaptable for general use.
