HELLA BRAKES 355129241 front brake rotor for the 2019-2021 Volkswagen Jetta and other vehicles gives the pads a coated, vented surface to grip. The disc is full-cast gray cast iron with a smooth, non-directional face.
Pedal pulsation, vibration under braking, grooves or a lip on the rotor face, or squealing can mean a rotor is worn, but pads, calipers or wheel bearings can produce similar signs, so find the cause before replacing anything. During a brake service, with the engine off, measure the rotor: 27 mm is the discard thickness.
It is listed for a wide range of Volkswagen and Audi models, including the 2018 Volkswagen Tiguan and the 2019-2025 Audi Q3. Front rotors are normally replaced as a pair, and the 2019-2021 Volkswagen Jetta takes two. This listing is one rotor, so plan on two for a 2019-2021 VW Jetta rotor replacement.
