Audi A6 Quattro Brake Pads and Rotors Kit​

Choosing Audi Brake Rotor And Pad Kits

Audi brake rotor and pad kits vary by the axle being serviced and the brake assembly fitted to the vehicle. A front package, a rear package and a four-wheel combination can serve different repairs, even before rotor size enters the decision. Keep the original brake configuration in view when comparing options. Matching the discs and pads to that configuration matters more than choosing a package because it has more pieces or a more elaborate surface pattern.

How Audi Brake Rotor Dimensions Affect Fit

The disc must sit in the right position between the pads and within the caliper bracket. Its outside diameter describes only one part of that fit. Thickness, mounting height and the center opening affect the installed relationship as well. A matching bolt pattern cannot compensate for a disc that sits too far inward or outward.

Audi brake combinations can specify different disc diameters and mounting dimensions, even when the packages cover the same axle. On a car with more than one factory brake option, the relevant dimensions help identify which replacement belongs on that axle. Record the existing brake size before comparing surface finishes so that a change in appearance does not obscure a difference in fit.

Vented And Solid Rotors In Audi Brake Kits

Vented discs have internal passages between two friction faces. Solid discs have no comparable internal passage. A front-and-rear combination can use a vented disc at the front and a solid disc at the rear; both remain correct only for their specified applications. The construction is part of the required brake design.

Drilled holes and slots are features of the friction faces. Internal vents are passages within the rotor body, so these descriptions can appear together on the same disc. When comparing Audi brake pads and rotors, separate the construction required by the vehicle from the available face designs. Neither a drilled pattern nor a slotted face establishes a particular stopping distance.

Deciding Between An Axle Kit And A Full Set

A rotor loses material as it works against the pads. Its discard thickness is the limit for continued service, while nominal thickness describes the new part. A remaining outer lip is not a useful substitute for measuring the working surfaces. Surface damage, corrosion and the condition of both sides also affect the repair decision.

When a disc requires replacement, plan the friction parts for the affected axle together. A complete front-and-rear package is useful when both axles need that work; it is not proof that every brake component on the vehicle needs replacement. Establish the condition of the existing brakes first, then choose a package whose contents correspond to the repair.
