Dorman - First Stop Drum Brake Wheel Cylinder P/N:W34334
Keep hydraulic pressure working at the rear shoes with this Dorman drum brake wheel cylinder, part number W37696 from the First Stop line. It is a direct-fit rear wheel cylinder for the 1987-1999 Dodge Dakota, engineered to be a direct match for the original drum brake wheel cylinder on that truck.
A wheel cylinder sits inside the drum brake assembly. When you press the brake pedal, hydraulic pressure from the master cylinder pushes its pistons outward and presses the brake shoes against the drum. Worn cups or a pitted bore can let fluid seep out and reduce braking force.
Signs a wheel cylinder may need replacing include brake fluid leaking inside the drum or at the backing plate, fluid-soaked brake shoes, a soft or low brake pedal, or the vehicle pulling to one side when braking. These symptoms can have other sources, so diagnose the cause before replacing parts. After installation, bleed the brake hydraulic system following the vehicle service information. This wheel cylinder is sold individually. Replacing the wheel cylinders on both sides together is recommended for balanced braking.

This part cross-references / interchanges with the following part numbers:
What does the Dorman W37696 wheel cylinder do?
It converts hydraulic pressure from the master cylinder into outward piston movement. That movement pushes the rear brake shoes against the drum when you press the brake pedal.
Does this wheel cylinder fit a 1987-1999 Dodge Dakota?
Yes. W37696 is a direct-fit rear drum brake wheel cylinder for the 1987-1999 Dodge Dakota. See the Buyer's Guide tab for application details.
What are the cups and boots made of?
Dorman makes this wheel cylinder with high-quality EPDM rubber cups and boots. The bores are surface-tested to give the pressure cups an optimum sealing surface.
What are signs a wheel cylinder may need replacing?
Common signs include brake fluid leaking inside the drum, fluid-soaked shoes, a soft or low pedal, or pulling while braking. These can have other causes, so diagnose before replacing.
Do I need to bleed the brakes after installing it?
Yes. Opening the hydraulic system lets air in, so bleed the brakes after installation and follow the vehicle service information for the correct procedure.
