250×40 Knott Brake Drum 5×112 – Heavy Duty Replacement for Caravan & Off-Road Camping Trailer Axles
This 250×40 Knott brake drum is a heavy duty replacement brake drum designed for European caravans, off-road camping trailers and adventure camper axles. Featuring a 250×40 mm drum size with a 5×112 mm bolt pattern, this Knott-compatible brake drum delivers superior stopping power and heat capacity for larger, heavier trailers that demand more from their braking systems.
Engineered to exact Knott heavy duty specifications, this 250×40 Knott brake drum bolts directly to standard 5×112 hub assemblies found on caravans and off-road campers rated from 1800 kg up to 2500 kg. The larger 250 mm diameter and 40 mm width provide increased braking surface area compared to standard 200×50 drums, ensuring consistent, fade-resistant stopping performance during long descents, mountain touring and fully loaded off-road expeditions.

Why Choose This 250×40 Knott Brake Drum
The 250×40 drum size is the European heavy duty standard for larger caravans and off-road campers that exceed the capacity of standard 200×50 drums. The increased diameter and wider drum face provide greater heat dissipation during sustained braking, reducing fade risk on mountain passes and improving overall safety for fully loaded adventure trailers.
