Purpose and fitment

The presented caliper housing has been designed specifically for the rear axle on the left side of the Audi SQ5 FY generation model. Thanks to the factory mounting geometry and the correct spacing for the 330x22 mm disc, the component allows for maintaining the correct position of the brake pads relative to the disc, which translates into stable and predictable operation of the braking system.

Its original Audi origin promotes precise fitment with the carrier, disc, and other system components, minimizing the risk of installation issues and improper brake pad wear.

Construction and technical properties

The caliper housing is a load-bearing element of the braking system, responsible for guiding the pistons and evenly pressing the pads against the disc. The solid, massive construction ensures adequate resistance to thermal and mechanical loads typical for the dynamic operation of SQ5 models.

Precisely machined guide surfaces and mounting seats enable the correct operation of the moving parts of the caliper, which promotes even distribution of braking forces across the entire surface of the disc. This, in turn, helps to reduce vibrations, noise, and uneven pad wear.

Application in the braking system

The left rear brake caliper housing in the Audi SQ5 FY plays a key role in stabilizing the operation of the entire system on the rear axle. It is responsible for:

• maintaining the correct position of the pads relative to the 330x22 mm disc,
• transferring forces from the pistons to the friction linings,
• ensuring adequate rigidity during intensive braking,
• cooperating with the factory brake force distribution system.

By maintaining the original specification, the component allows for the preservation of factory braking performance parameters, which is important for both safety and the durability of other system components.

Condition and benefits of choosing a used part

The offered caliper housing comes from the used parts segment, which allows for an economical repair of the braking system while maintaining the original Audi design. Choosing such a solution is particularly beneficial in the case of post-accident repairs or replacing a mechanically damaged component when you want to maintain the factory specification without the need to invest in a new subassembly.

Before installation, a standard service procedure is recommended: thorough cleaning, inspection of working surfaces, and – if necessary – replacement of wear items (seals, guide pins, mounting bolts) in accordance with the vehicle manufacturer's recommendations.

Safe selection and additional technical information

To ensure that the selected caliper housing will be fully compatible with your Audi SQ5 FY, it is worth verifying compatibility using the OEM part number and interchangeable numbers available in the technical specification. This allows you to avoid installation problems and guarantees correct cooperation with the 330x22 mm disc and other system elements.

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

When selecting used braking system components, it is worth following a proven verification procedure.
