UL-Disc with HOT (High Output Technology)
The Ultimate in Air Disc Brake Performance & Durability

TSE innovated the double-diaphragm HOT (High Output Technology) chamber used worldwide for disc brake applications. Now TSE has taken disc brake actuators to the next level with the ultimate in product durablity and corrosion resistance.

Innovative Design

UL-Disc features a 100% steel inverted spring bottom housing that reduces both spring coil-to-coil contact and spring coil-to-spring housing contact. The all-steel design provides a durable, air-tight center section that virtually eliminates leaks and structural failures, while the recessed pressure plate allows for a shorter and more compact chamber.

Premium Quality

TSE is an ISO 9001 and KBA certified company. As an OEM premium direct fit and aftermarket replacement, UL-Disc is the premium brake for your heavy-duty disc brake trucking application.

Tough Main Spring

UltraLife main spring adds a proprietary base coating in addition to TSE's multi-stage coating system for the ultimate in corrosion protection. Tested to double SAE standards, UL-Disc’s main spring actually exceeds SAE dry cycle testing requirements in a slurry environment.

Complete In-House Testing

UL-Disc brake actuators undergo rigorous in-house testing in TSE’s comprehensive testing lab. Tests include variable pressure cycle testing, vibration testing, hot cell cycle testing, salt spray testing, cold cell leak/operational testing and slurry testing

Superior Corrosion Resistance

With TSE’s exclusive in-house process, all parts of the UL-Disc actuator receive a multi-stage pre-treatment prior to e-coat and an extra layer of polyester powder coating protection.

Seven Year Warranty

Industry leading warranty – up to 7 years.

HOT (High Output Technology)

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 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.
