Bring hydraulic pressure back to your rear drum brakes with the Dorman - First Stop Drum Brake Wheel Cylinder W37977. When the brake pedal is applied, this cylinder converts brake-fluid pressure into mechanical force that pushes the brake shoes outward against the drum. It installs in the rear-left position as a direct-fit replacement for the 1992-2000 Hyundai Elantra, 1994-1998 Hyundai Sonata, 1995-1999 Hyundai Accent, and 1997-2001 Hyundai Tiburon (All engines), engineered to drop in like the original wheel cylinder on the listed applications.
- Aluminum body: aluminum construction with a 0.75 in bore.
- EPDM sealing: made with high-quality EPDM rubber cups and boots for long-lasting performance.
- Ready to bleed: ships with a bleeder screw (bleeder screw cap not included); M10 x 1.0 inlet thread (10 mm, 1.0 pitch).
- Tested bore: the cylinder bore is surface-tested to provide an optimum sealing surface for the pressure cups.
Signs the original wheel cylinder may need replacing include brake fluid leaking at the wheel, a soft or sinking pedal, or contaminated shoes. If a failed wheel cylinder is the cause, replacing it while servicing the drum brakes helps restore proper hydraulic operation.
