Cummins Introduces QuikDisc Air Disc Brake System for Heavy Fire Truck Rear Axles
Cummins Inc. unveiled QuikDisc, a patented rotor solution that brings air disc brakes to heavy fire truck rear axles, enabling faster rotor replacement and improved braking performance.
- 33,500 pounds
- 3–4 hours per wheel end
- Less than 1 hour
What Happened
Heavy-duty fire trucks require reliable braking under high weights and emergency conditions, but rear axles have traditionally relied on drum brakes due to durability concerns with disc brakes. Cummins' new QuikDisc system adapts air disc brakes for up to 33,500-pound rear axle ratings, addressing both performance and serviceability.
- 3–4 hours (traditional)
- Less than 1 hour (QuikDisc)
- Yes (traditional) / No (QuikDisc)
- Shorter stopping distances
- More consistent braking performance
- Improved resistance to brake fade
- Easier visual inspection
- Faster brake pad replacement
Why this matters
For fire departments, QuikDisc reduces brake rotor replacement time from up to 16 hours to less than one hour per service event, lowering maintenance costs and improving vehicle uptime over a fire truck's 15-20 year lifespan.
Terms in This Story
- Air disc brake
- A brake system that uses pressurized air to clamp brake pads against a rotor, creating friction to slow the vehicle.
- Drum brake
- A brake system where brake shoes press outward against a rotating drum to create friction.
- Rotor
- The disc component in a disc brake system that rotates with the wheel and is clamped by brake pads.
