Audi SQ5 FY Rear Brake Caliper Wheel Braking Unit Right O/S 80A615404B

The Audi SQ5 FY rear right brake caliper is an original component of the braking system, designed for installation on the rear axle on the passenger side. Thanks to its factory Audi design, it ensures precise cooperation with the disc, pads, and hydraulic system, which translates into stable, predictable braking and proper distribution of braking force between the axles.

Intended Use and Fitment for Audi SQ5 FY

The presented caliper has been specifically designed for the Audi SQ5 FY generation, taking into account the characteristics of its powerful drivetrain and higher thermal loads typical for sport versions. Its placement on the vehicle is the rear, right side, which facilitates unambiguous identification when planning repairs or replacements of braking system components.

Thanks to the use of original mounting geometry and the correct piston diameter, the caliper works with factory discs and pads, maintaining the parameters specified by the vehicle manufacturer. This solution is particularly important for dynamic driving, where repeatable braking effectiveness and vehicle stability are crucial.

Design and Function in the Braking System

The brake caliper plays a key role in converting hydraulic pressure into clamping force of the pads against the disc. In the case of the Audi SQ5 FY, this component has been optimized for:

• proper distribution of braking force between the front and rear,
• maintaining even pad pressure against the disc,
• stable operation across a wide range of operating temperatures.

The original caliper from this series ensures compatibility with the factory ABS/ESP system, which is important for the correct functioning of active safety systems. Using the correct component on the right side of the rear axle reduces the risk of uneven braking, vibrations, or the vehicle pulling to one side during intense braking.

Condition, Origin, and Benefits of Choosing a Used Part

The offered Audi brake caliper comes from the Brake Calipers and Brackets category and is a used component, allowing for economical repair while maintaining original manufacturing quality. Choosing an OEM salvaged part is beneficial wherever maintaining factory specifications is a priority, while also optimizing service costs.

A used caliper of this type is a good solution in situations where the existing component has suffered mechanical damage, corrosion leading to seized guide pins, or system leaks. After proper installation and bleeding of the braking system, it can restore full functionality to the rear right brake section of the Audi SQ5 FY.

Installation and Maintenance Tips

When replacing the rear right caliper on an Audi SQ5 FY, it is recommended to:

• check the condition of the brake discs and pads and replace them as a pair on the axle if necessary,
• inspect brake lines for corrosion and leaks,
• thoroughly bleed the system after installation, following the vehicle manufacturer's procedures,
• verify the correct operation of the parking brake (if integrated with the caliper) during initial road tests.

Professional installation by an experienced service center allows for the full utilization of the original caliper's potential and reduces the risk of subsequent braking system issues.

Expanding the Braking System and Selecting Other Components

If you are planning a comprehensive repair or upgrade of the braking zone in your Audi and need other components from the same group, such as additional calipers, brackets, or mounting holders, check the available parts in the Audi Brake Calipers and Brackets category.

When selecting used braking system components – including calipers, discs, or ABS components – it is advisable to follow a proven procedure for assessing their technical condition.
