Double diaphragm chamber Ultra-Life (ULP)
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.
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.
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.
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.
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.
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.
Warranty
Industry leading warranty – up to 7 years.
