Severe Duty

A New Level of Performance and Corrosion Resistance

TSE's unique, innovative Severe Duty spring brake design is available in both the UltraLife and OmniBrake models. Engineered to handle your toughest heavy duty applications, including vocations such as refuse, concrete, dump trucks and school buses, TSE Severe Duty brakes offer the industry?s longest service life and are an OEM standard direct fit and an OEM quality replacement.

Accordian Style Boot Cover

Severe Duty brakes protect the push rod with an accordion style boot cover made from neoprene rubber, which allows fewer outside contaminants for increased durability and longer life.


Available in a 2430 and 3030 size in 2.5" or 3" stroke, TSE Severe Duty spring brakes are an OEM quality replacement.

Stainless Steel Clevis Pin

Helps prevent seizing at connection between chamber and slack adjuster for an increased resistance to chemicals and excellent protection for salt water port applications.

In-House Testing Labs

As the only chamber manufacturer that offers all steel construction, TSE's in-house full immersion e-coating also guarantees 100% coating and consistent thickness for the best corrosion protection. Through their in-house lab TSE conducts extensive testing on brakes including high pressure cycle, vibration, hot cell cycle, salt spray and slurry.

Breather Holes Are Plugged

All breather holes on the Severe Duty are plugged except for two holes per tandem, allowing the chamber to drain and breathe while protecting it from outside material, ultimately extending service life of the brake.


Severe Duty chambers come with an UltraLife 3-year or OmniBrake 2-year warranty, with extended options available for National Fleet Partner customers.
