Key Benefits
Superior Heat Management: The high-mass design acts as an efficient heat sink, maintaining stable friction levels even under high-cycle braking.
Machined to Perfection: Each drum is CNC-machined to ensure perfect concentricity, reducing "pedal pulsation" and uneven lining wear.
Increased Durability: Our casting process minimizes microscopic porosity, leading to a higher resistance against thermal cracking (heat checking).
Ready to Install: Pre-balanced and treated with a light anti-corrosion coating, saving your technicians time during installation.
FAQ
Q1: Is the 7358 drum suitable for steer axles?
A: The 7358 is primarily designed for rear drive axles or trailer axles that require a 15" x 4" braking surface. Always check your vehicle service manual for axle-specific requirements.
Q2: Does this drum require additional balancing?
A: No. Our 7358 drums are dynamically balanced at the factory. You can install them directly "out of the box."
Q3: How do I know if I have a 7358 or a different 15-inch drum?
A: The most important measurements are the Pilot Diameter (8.78") and the Overall Depth (8.81"). Please compare these with your existing drum or contact our tech support.
