Overview

Ensure reliable stopping power and keep your commercial vehicle completely DOT-compliant with this premium Sealed Type 30/30 Spring Brake by FleetPro Parts & Tires. Manufactured to strict Fleet Standard specifications, this heavy-duty air brake chamber is a critical safety component for any Class 8 truck or trailer. A leaking diaphragm or rusted internal power spring will cause brake drag, sluggish response, and immediate weigh station failures. We stock these heavily right here in our Hanover Park, Illinois warehouse to ensure lightning-fast shipping for fleets, diesel repair shops, and owner-operators nationwide.

Heavy-Duty Stopping Power: The Sealed Type 30/30 Spring Brake Advantage

This Sealed Type 30/30 Spring Brake (Part # 179.SB3030S) is engineered for maximum longevity in harsh, corrosive environments. Featuring a standard 2.5-inch stroke, it provides the precise pushrod travel required for optimal slack adjuster geometry and brake shoe engagement. The fully sealed housing design is a major upgrade for vocational and winter-driven trucks, as it actively prevents road salt, moisture, and debris from contaminating the internal parking spring, drastically reducing the risk of premature spring fracture and chamber failure.

As we continue to build the largest inventory of commercial truck air brake components in Illinois, we prioritize wheel-end safety hardware that offers reliable, "bolt-on" aftermarket performance. Serving as a professional-grade replacement for highly searched industry part numbers like Haldex GC3030, Bendix 165255, and Freightliner 3030TS, this brake chamber is a shop essential. Manufactured by Automann, it delivers the rugged, heavy-duty durability your fleet demands to stay safely on the road.
