Dorman - First Stop Drum Brake Wheel Cylinder P/N:W10581
Turn hydraulic pressure into braking force at the rear drum with the Dorman - First Stop Drum Brake Wheel Cylinder W610142. It drops in as a direct-fit replacement for the rear right position on the 1997 GEO METRO and the 1999-2001 CHEVROLET METRO.
A wheel cylinder is a wear item in any drum brake. Signs it may need replacing include brake fluid seepage behind the rear drum, a soft or slowly sinking brake pedal, or weaker braking at that wheel. If a leaking or seized wheel cylinder is the cause, this unit replaces it. Bleed the brake system after installation, and inspect the shoes, springs, and hardware while the drum is off. It is good practice to service the wheel cylinder on the opposite rear wheel at the same time for balanced braking.

This part cross-references / interchanges with the following part numbers:
What does the W610142 wheel cylinder do?
It is the hydraulic actuator in a rear drum brake: brake-line pressure pushes its internal pistons outward, forcing the brake shoes against the drum to slow the wheel.
Which vehicles does this wheel cylinder fit?
It is a direct-fit replacement for the rear right position on the 1997 GEO METRO and the 1999-2001 CHEVROLET METRO. Check the Buyer's Guide tab to confirm your vehicle.
Where does this wheel cylinder mount?
It is cataloged for the rear right wheel position on the drum-brake system.
How do I know if my wheel cylinder is failing?
Signs include brake fluid seepage behind the drum, a soft or sinking brake pedal, or reduced braking at that wheel. Diagnose the cause before replacing.
Do I need to bleed the brakes after installing it?
Yes—opening the hydraulic system means you should bleed the brakes afterward to remove air, and inspect the shoes, springs, and hardware while the drum is off.
