This Replacement Deemaxx Piston Boot is a genuine-style service part specifically designed for DeeMaxx 3,000lb to 6,000lb (3K-6K) disc brake calipers. This flexible rubber seal is the first line of defence for your braking system, protecting the internal piston from road grime and moisture.
Product Overview
Maintain the peak performance of your DeeMaxx braking system with this high-quality dust boot. In marine and off-road environments, salt, sand, and dust can easily infiltrate the caliper housing. This boot creates a watertight seal around the piston, preventing corrosion and sticking, which ensures smooth brake retraction and consistent stopping power.
Key Features
Precision Fit: Engineered specifically for the piston diameter found in DeeMaxx 3K, 3.5K, and 6K hydraulic calipers.
High-Flex Rubber: Manufactured from a durable, heat-resistant EPDM rubber compound that maintains its seal even under extreme braking temperatures.
Protective Barrier: Shields the precision-machined piston surface from salt water, brake dust, and debris that can cause “piston pitting” or seized brakes.
Easy Maintenance: A cost-effective way to overhaul your calipers without needing to replace the entire unit.
Technical Specifications
Compatibility: DeeMaxx Hydraulic Calipers (3,000lb to 6,000lb ratings)
Material: Industrial Grade EPDM Rubber
Part Type: External Piston Dust Boot / Seal

Why Replace Your Boots?
Cracked or perished boots allow contaminants to enter the caliper, leading to rust on the piston walls. If you notice fluid leaks or brakes that “drag” after releasing the pedal, it’s often a sign that the boots and internal seals need to be replaced immediately.
