Beck/Arnley Drum Brake Wheel Cylinder P/N:072-9338

Restore firm, even drum-brake action at the rear with the Beck/Arnley Drum Brake Wheel Cylinder 072-9338 (also written 0729338). It installs as a direct-fit replacement for the 1998-2003 Toyota Sienna — see the Buyer's Guide tab for engine-level fitment. Mounted in the rear drum brake, the wheel cylinder receives hydraulic pressure from the brake system and pushes its pistons outward to press the brake shoes against the drum; when the internal cup seals wear or leak, replacing the cylinder with this unit restores that function.

• Complete new assembly: supplied as a full new wheel cylinder, not a rebuild.
• OE form, fit and function: engineered to replace the Original Equipment unit on foreign-nameplate applications.
• Quality materials & construction: built with high-quality materials for durable service.
• Application specific: matched to the listed vehicle.

Signs the original cylinder may need replacing include brake fluid seeping at the wheel, a soft or sinking pedal, or uneven rear braking. Diagnose the cause before replacing. Sold as a single cylinder.
