Designed for smooth, quiet rear braking, the BOSCH brake pad BE1898 is a rear disc brake pad set built around platform-specific NAO-ceramic friction formulations. It is a direct-fit replacement for many Audi vehicles, among them the 2018-2019 Audi RS5, the 2021 Audi RS5 Sportback and the 2017-2020 Audi A4; see the Buyer's Guide tab for the full list.
These pads draw on Bosch's OE braking heritage, which dates back to 1927. Brake pads wear with every stop. Signs a rear set may need replacing include squealing or grinding when braking, a pad-wear warning, or visibly thin friction material. Inspect the rotors whenever you replace the pads. See the Buyer's Guide tab for engine-level fitment details.

Is this the right 2017-2020 Audi A4 brake pad for the front or rear?
BE1898 is cataloged for the rear position on the 2017-2020 Audi A4 and on the other listed Audi models. See the Buyer's Guide tab for engine-level fitment.
What friction material do these Bosch pads use?
Bosch uses advanced, platform-specific NAO-ceramic friction formulations that are formulated and tested by its engineers.
What do the multi-layer shims on these pads do?
The pre-attached OE-style multi-layer shims bond rubber and steel, helping lower noise and adding strength and corrosion resistance.
Is brake lubricant included?
Yes. Bosch includes synthetic lubricant with all applications to help reduce resistance on sliding contact points.
What signs mean my rear brake pads may need replacing?
Squealing or grinding when braking, a pad-wear warning, or thin friction material can indicate worn pads. Have the brakes inspected, including the rotors, to confirm the cause.
