Carquest Wearever Drum Brake Wheel Cylinder

Part No. WCA37786 Warranty Details  

See if this part fits a specific vehicle.

Check Vehicle Fit

Direct replacement Wheel Cylinders are designed to fit specific vehicle applications and to ensure a proper fit every time. Normal wear may cause piston seals to leak. Corrosion and pitting can also occur inside Wheel Cylinders as moisture builds up in the brake fluid. A leaky Wheel Cylinder can be dangerous to the driver, causing gradual softening of the brake pedal and creating brake pull to one side.

Product Features:
  • All Wheel Cylinders are made with high quality EPDM rubber cups and boots for long lasting performance
  • Wheel Cylinder bores are surface tested to ensure an optimum sealing surface for the pressure cups
  • Due to repair time and cost, it is more desirable to replace instead of repair Wheel Cylinders
  • Recommended replacement is suggested when servicing drum brake

    Installed quick and seems to work great, although I will probably rebuild the stock one and have it standing by should I need another.
