When it comes to high-performance braking, stopping power doesn’t begin and end with pads and rotors.
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.
Engineered for extreme conditions
While standard caliper repair kits are typically designed to meet OEM tolerances for daily use, these kits go several steps further.
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 would quickly break down.
At the core of the system are high-temperature silicone dust boots, rated up to 270°C. To put this into perspective: average street use generates around 130°C at the caliper, while track driving can push that temperature up to 260°C.
It is worthwhile noting that standard caliper replacement kits usually offer seals that are rated for significantly lower temperatures. Using such kits on a performance vehicle can lead to premature and frequent seal failure that potentially results in oil leaking from the caliper, and the consequent loss of braking power.
Furthermore, whilst standard caliper repair kits may initially provide a satisfactory repair of worn or damaged seals, they can be subject to a short life span when used under challenging conditions.
This may result in the frequent need for caliper repair — a process that can be time consuming and — for some users — challenging. DBA’s Caliper Repair kits last multiple times longer than standard repair kits, thus saving time and stress.
DBA’s kits also include custom-blend piston seals, engineered for durability under thermal and mechanical stress — helping prevent issues like fluid leakage, brake fade, or premature wear.
All these features help ensure consistency and reliability over extended use, even in the harshest braking environments, providing peace of mind for the user. No premature caliper failure whilst out on the track! No stress wondering if the caliper seals are going to make it through the next race!
Built-in temperature tracking
To support ongoing performance monitoring, each kit includes adhesive temperature indicator strips. These offer a simple, visual way to review how hot calipers are getting over time — providing a valuable reference point for maintenance and giving drivers and technicians deeper insight into the system’s real-world workload.
It’s a practical layer of information, particularly useful for vehicles that are pushed beyond typical operating ranges.
Rebuild, don’t replace
For vehicles already equipped with upgraded rotors, pads, and fluid, factory-spec caliper internals can become the limiting factor. Rather than replacing the caliper entirely, this solution allows it to be rebuilt to a higher standard, preserving the original housing while upgrading its resilience and performance characteristics. It’s an efficient, performance-forward approach that helps extend the lifespan of critical components while enhancing braking capability.
Trusted components, certified manufacturing
Every Upgrade Performance Caliper Repair Kit is produced in Europe under IATF 16949-certified processes — an automotive quality standard that ensures consistency, traceability, and performance you can rely on. Whether the application is track-focused or street-tuned, these kits provide a well-rounded solution backed by motorsport-grade development and engineering know-how.
In performance braking, there’s no room for shortcuts. DBA’s Upgrade Performance Caliper Repair Kits by Frenkit deliver what matters most — thermal resistance, mechanical strength, and real-world reliability.
