Feed hydraulic pressure to the rear drum brake shoes with the Beck/Arnley Drum Brake Wheel Cylinder 072-9871. It installs as the rear left wheel cylinder and is an application-specific, direct-fit replacement for the 2005-2016 Smart Fortwo (see the Buyer's Guide tab for engine-level details). Inside a drum brake, the wheel cylinder takes fluid pressure from the master cylinder and uses its internal pistons to push the brake shoes outward against the drum; if the original cylinder on your rear left corner is leaking or sticking, this replaces it.
Signs the original wheel cylinder may need replacing include brake fluid seeping at the backing plate, a soft or sinking pedal, or contaminated shoes on that corner. Diagnose the cause before replacing.
