Put hydraulic muscle back into the rear drum brake — the Dorman - First Stop Drum Brake Wheel Cylinder (MPN W610115) converts brake-line hydraulic pressure into the mechanical force that pushes the brake shoes outward against the drum. It drops in as a direct-fit replacement for the rear right position on the 2003-2005 Honda Civic.
- Hydraulic actuation: the internal piston(s) receive pressurized brake fluid and drive the brake shoes against the drum.
- Cataloged position: the rear right wheel cylinder for the listed application.
- Direct fit: a direct-fit replacement for the 2003-2005 Honda Civic; sold individually.
Brake fluid seeping or leaking from the cylinder, a soft or spongy pedal, or weak, uneven rear braking are signs this component may need replacing — diagnose the cause before installing, since these symptoms can have other sources. For even, balanced braking, replacing the wheel cylinder on the opposite side at the same time is a common best practice.
