Dorman - First Stop Drum Brake Wheel Cylinder P/N:W610237

Keep your rear drum brakes applying firmly with the Dorman - First Stop Drum Brake Wheel Cylinder W610237. It drops in as a direct-fit replacement for the 2016 Scion iA and the 2017-2018 Toyota Yaris iA (All engines), where it mounts in the rear drum brake and uses hydraulic pressure to push the brake shoes outward against the drum. Dorman engineered it to match the fit, function and performance of the original wheel cylinder, and each unit is manufactured and tested for quality assurance.

• Sealing components: built with high-quality EPDM rubber cups and boots.
• Tested bore: the cylinder bore is surface-tested to provide an optimum sealing surface for the pressure cups.
• Cast iron body: 11/16 in inside diameter with an M10 x 1.0 inlet thread.
• Bleeder screw included (bleeder screw cap not included).

Replacing the wheel cylinder while servicing the drum brakes is a fast, cost-effective way to help restore proper hydraulic operation. Signs this part may need replacing include brake fluid seeping at the rear drum, damp brake shoes, or a spongy pedal — diagnose the cause before ordering. These applications use two (one per rear wheel); this listing is for one, so order 2 for a complete rear-axle replacement. Made in China.
