PowerStop JBR1789EVC front brake rotor for the 2019-2024 Subaru Ascent slows the vehicle as the brake pads clamp down on its surface. As a PowerStop brake rotor, it is made to original equipment specifications for fitment, weight, vane count and performance.
A worn disc brake rotor can show up as pedal pulsation, grooves or heavy rust on the friction surface, or noise when braking. Those signs can mean this part is worn, though the brake pads or a sticking caliper can also be behind them, so find the cause before replacing the rotor.
This listing is one of the front brake rotors for the 2019-2024 Subaru Ascent, a direct original equipment fit and function. The other side of that axle is normally done at the same time.
