When it comes to high-performance braking, the internal components of the caliper—dust boots, piston seals, and related hardware—are critical to the system’s integrity, especially under heat, pressure, and repeated stress.

That’s why DBA has partnered with industry-leading, Europe-based brand Frenkit to introduce the Upgrade Performance Caliper Repair Kit – a purpose-built solution for demanding environments, whether it’s competition, spirited street driving, or track-day use.

Factory-standard caliper internals can become the limiting factor in a braking system. Rather than replacing the caliper entirely, DBA’s repair kit solution allows it to be rebuilt to a higher standard, preserving the original housing while upgrading its resilience and performance characteristics.

Developed through rigorous R&D and tested in both lab environments and motorsport conditions, each component is designed to maintain integrity in scenarios where conventional materials – as originally used in calipers and repair kits – can break down prematurely due to the limitations in the materials’ heat handling properties.

DBA’s Caliper Repair kits contain high-temperature piston seals, silicone dust boots, adhesive temperature indicator strips, and – depending the on application – a set of high-quality replacement pistons.
