Purpose and technical fitment

The presented caliper is designed for operation on the rear left side of the vehicle, which guarantees compatibility with the brake system geometry of the Mini One R60 and R61. The original OEM design allows for maintaining factory braking force parameters, even pressure of the pads against the disc, and proper cooperation with other system components.

Thanks to the use of a factory housing and correct mounting geometry, the caliper allows for installation in place of a worn or damaged part without the need for modifications, which is particularly important for maintaining safety and predictable vehicle behavior during braking.

Benefits of using an original brake caliper

Choosing an original, used caliper for the Mini One R60/R61 is a solution that allows you to balance cost control with the preservation of factory parameters. Such a component:

• maintains the proper operating characteristics of the brake system,
• ensures compatibility with factory lines, pads, and discs,
• reduces the risk of installation issues thanks to serial mounting points,
• allows for economical repair without sacrificing OEM parts.

For users who value the technical consistency of their vehicle, it is particularly important that the original Mini brake caliper was designed specifically for the platform, which translates into predictable operation of the ABS/ESP system and even pad wear.

Application in the Mini One R60 R61 brake system

This caliper model operates in a critical safety zone, responsible for stable braking of the rear axle. A properly selected and functional caliper:

• maintains appropriate pressure on the brake pads during linear and emergency braking,
• works with driver assistance systems, ensuring an even distribution of braking forces,
• reduces the risk of the vehicle pulling to one side during heavy braking.

Thanks to its dedicated placement on the vehicle, this component is the right choice when replacing a caliper on the rear left side, where compliance with Mini's factory specifications is required.

Product condition and practical aspects

The offered brake caliper is used, which allows for a significant reduction in repair costs compared to a new OEM part, while maintaining the original design. This solution is particularly beneficial for comprehensive brake system maintenance when more than one component is being replaced.
