Dorman - First Stop Drum Brake Wheel Cylinder P/N:W34043
Convert hydraulic line pressure into the force that pushes the front brake shoes outward against the drum with the Dorman - First Stop Drum Brake Wheel Cylinder W7379. It installs as a direct-fit replacement on the 1946-1952 Jeep Willys (All engines), which run two front wheel cylinders — one per side. Dorman engineered this cylinder to match the original's fit, function and performance on the listed applications, and each unit is manufactured and tested for quality assurance.
Replacing the wheel cylinders while servicing drum brakes is a fast, straightforward way to keep the hydraulic side of the system sealed. If a worn or leaking front wheel cylinder is the cause of a soft pedal or fluid seepage at the backing plate, this replaces it. Country of origin: Taiwan.
