Convert brake-line hydraulic pressure into the force that pushes the brake shoes outward against the drum with the Dorman - First Stop Drum Brake Wheel Cylinder W45961. Cataloged for the front-right position, it's built to drop in and work like the original wheel cylinder on the listed classic American Motors models.

Fits the front-right position on: 1965-1974 AMC Ambassador, 1967-1968 AMC American, 1968-1970 AMC AMX, 1965-1966 AMC Classic, 1972-1976 AMC Gremlin, 1970-1976 AMC Hornet, 1968-1974 AMC Javelin, 1966-1967 AMC Marlin, 1971-1974 AMC Matador, and 1967-1970 AMC Rebel (All engines).

  • Cast-iron body: the wheel cylinder body is cast iron, and the bores are surface-tested for an optimal sealing surface for the pressure cups.
  • EPDM sealing parts: made with high-quality EPDM rubber cups and boots for long-lasting performance.
  • Bleeder screw included: a bleeder screw is included; the bleeder screw cap is not included.
  • Sized to fit: 1.188 in inside diameter with a 3/8-24 UNF inlet thread (3/8 thread diameter).

Signs the original may need replacing include brake fluid weeping at the wheel cylinder, a soft or sinking pedal, or drum brakes that grab unevenly — if a failed wheel cylinder is the cause, this replaces it. Replacing the cylinder while servicing the drum brakes is a fast, cost-effective way to help maintain drum-brake performance. Wheel cylinders work as a pair on the axle, so replacing both sides together is best practice for even, balanced braking; this listing is for one cylinder (package contains one). Country of origin: China.

Frequently Asked Questions

What does this drum brake wheel cylinder do?

It uses hydraulic pressure from the brake line to push the brake shoes outward against the drum. When you release the pedal, the return springs push the shoes back and the cylinder pistons retract.

Which vehicles and position does W45961 fit?

It's cataloged for the front-right position on classic AMC models including the 1965-1974 Ambassador, 1968-1970 AMX, 1972-1976 Gremlin and 1970-1976 Hornet — see the Buyer's Guide tab for the full list.

Is a bleeder screw included?

Yes, a bleeder screw is included. The bleeder screw cap is not included.

What are the bore size and inlet thread?

The wheel cylinder has a 1.188 in inside diameter and a 3/8-24 UNF inlet thread (3/8 thread diameter). The body is cast iron with EPDM rubber cups and boots.

Should I replace both wheel cylinders?

This listing is for one cylinder. Because wheel cylinders work as a pair on the axle, replacing both sides together is recommended for even, balanced braking.
