Dorman First Stop Drum Brake Wheel Cylinder

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.
  • 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

Dorman First Stop Drum Brake Wheel Cylinder is rated 4.8 out of 5 by 25.
Rated 5 out of 5 by from Exact Replacement Exact replacement for a 96 Civic. Installation was straight foward. Does seem to be of oem quality. Time will tell how long it will hold up. I replaced everything in the rear drums, hence I had to replace the cylinder due to it leaking. It definitely solved leaking issues & functions as it should. Time will tell on durability. Most time consuming was bleeding the lines.

Rated 4 out of 5 by from Exact fit, good price Pepboys is convenient and at reasonable prices. The parts are good quality. Brake cylinders are easy, but you should research installation on YouTube before you attempt this repair. You can damage a new cylinder and pop the hydraulic piston out if not done properly

Rated 4 out of 5 by from It worked as described Not much to say about it, it fit as it should and was not hard to install. I won't know if it is good quality until I put some miles on the car.

Rated 1 out of 5 by from I wasn't able to use the new wheel cylinder. The reason that I bought a new wheel cylinder was because the bleed air valve on my other older wheel cylinder was stripped. I attempted a couple times to buy a new bleed air valve, but even though Pep Boys understood the exact model of the wheel cylinder I was using, the bleed air valve that was issued to me was incorrect (too small in diameter). I had no choice but to buy a new wheel cylinder. During the installation process, I noticed that the opening (which was angled towards the front of the car) for the wheel cylinder brake line was located on the forward portion of the wheel cylinder. The brake line on my Mustang approaches the wheel cylinder from the rear of the wheel and the angle was too great to make the connection. The opening of the older wheel cylinder with the stripped brake line was angled towards the rear of the car. I ended up removing the bleed air valve from the new wheel cylinder and installing it on my older wheel cylinder. None of this should have happened! Pep Boys should have either been able to sell me the correct bleed air valve or there should have been options for wheel cylinders dependent on the particular side of the vehicle it was being used on.
