Purpose and technical fitment

The presented caliper has been designed specifically for the front axle on the right side of the second-generation Ford Focus in the ST version with a petrol engine. Thanks to this, it maintains the correct mounting points, geometry, and operating parameters, which facilitates installation and ensures proper cooperation with the brake disc, pads, and brake line.

The component comes from the Ford manufacturer's line, which means maintaining factory manufacturing tolerances, appropriate body rigidity, and predictable behavior during intensive braking. This is particularly important in high-performance cars such as the Focus ST, where the braking system operates under more demanding conditions.

Performance characteristics and role in the braking system

The front right brake caliper is responsible for evenly pressing the pads against the disc, stabilizing braking force, and maintaining the correct operating path of the pads. In practice, this translates into:

• consistent, predictable brake pedal operation during daily driving,
• appropriate vehicle stability during emergency braking,
• correct wear of pads and discs on the right side of the front axle,
• maintaining the factory braking characteristics of the ST version.

Thanks to the preservation of the original design, the caliper works with factory braking system components without the need for installation modifications or additional alterations.

Condition, origin, and benefits of choosing a used part

The offered brake caliper is a used component, which allows for a significant reduction in repair costs compared to a new part, while maintaining the manufacturer's original specifications. This is a good solution for users who want to restore the efficiency of the braking system while controlling their service budget.

Choosing an original, used Ford caliper instead of cheap replacements allows for maintaining material and structural consistency of the entire system, which is important for durability and stability of braking parameters in the long term.

Support with selection and expansion of the braking system

If you are planning a comprehensive repair or upgrade of the braking zone in your Ford and need other elements from the same group, such as additional calipers, brackets, or supports, check out the available parts in the Ford brake calipers and brackets category.

When selecting used braking system components – especially in higher-power cars – it is worth following proven verification procedures. Practical tips on what to look for when buying discs, calipers, and ABS components can be found in the article "Second-hand braking system: how to safely choose discs, calipers, and ABS?", which serves as a useful supplement when planning brake repairs or upgrades.

Summary

Ford Focus Mk2 ST Brake Caliper Housing Front Right O/S is a functional solution for drivers looking for an original component for the petrol version, ensuring proper fitment and stable operation of the braking system. By choosing this element, you gain consistency with the vehicle's factory design, predictable behavior during braking, and a favorable cost-to-quality ratio in the used parts segment.
