HOT - High Output Technology

A More Powerful Spring Brake in a Smaller Package

As the first double-diaphragm chamber used worldwide for disc brake applications, TSE's High Output Technology (HOT) chamber is a proven alternative to piston type disc brakes. HOT chambers offer higher output performance for your S-cam drum brake and disc brake application when compared to standard double-diaphragm chambers, and at a lower cost than piston chambers. HOT brakes are ideal for replacing piston brakes that are typically used on buses and other severe-duty applications.

Patented Design

Featuring a lighter weight and smaller envelope size, the HOT brake's patented housing design, HOT diaphragm and HOT pressure plate increase performance while improving effective surface area. In addition, internal dust boot and optional rod guide ensure longer service life and improved protection against corrosion. A reduced profile (RP) design is available for special fitment needs, where every millimeter counts.

Size/Stroke

HOT chambers are available in a 2.5" or 3" (65mm or 76mm) stroke, with US or metric threads for ports and mounting hardware.

Powerful Parking Performance

Achieve a higher parking or emergency force in a smaller profile while maintaining low hold-off pressure with a HOT brake. Also ideal for other severe-duty applications where you need higher parking force for added safety.

In-House Testing Lab

HOT chambers receive extensive testing through TSE's in-house lab for optimum performance, including tests such as variable pressure cycle, vibration, hot cell cycle, salt spray and slurry.

Corrosion Protection

All steel HOT brakes receive TSE's in-house full immersion e-coating to ensure 100% coating for the best corrosion protection.

Warranty

HOT chambers are available with a standard 3-year warranty, with an extended warranty available for National Fleet Partner customers.
