A-Premium Rear Drum Brake Wheel Cylinder 13/16" Bore Cast-Iron Direct Replacement

This A-Premium rear drum brake wheel cylinder is a cast-iron replacement with a 13/16" (0.813") bore designed to restore rear braking performance on compatible Jeep, Dodge, Plymouth and Chrysler models.

Engineered to match factory-style dimensions and fitments, this wheel cylinder serves as a direct replacement for rear driver and passenger sides on a range of late‑1980s to early‑2000s vehicles. It includes the internal bleeder screw, uses a 3/8-24 inlet thread, and is pressure- and high‑temperature tested to help ensure dependable operation under typical driving conditions. Check your vehicle details before ordering to confirm fitment.

Which vehicles will this wheel cylinder fit?

This cylinder is compatible with multiple Chrysler, Dodge, Plymouth and Jeep models, mostly European-built or export configurations for certain years. It fits rear applications on vehicles equipped with 9-inch drum brakes and covers both driver and passenger sides where specified.

• Chrysler Town & Country 1991–1993 (European-built)
• Dodge Caravan/Grand Caravan 1991–1993 (European-built)
• Plymouth Grand Voyager/Voyager 1991–1993 (European-built)
• Jeep Cherokee 1990–2001 (various non‑ABS and export 9" brake configurations)
• Wrangler and TJ applications listed for 1990–2000 as specified (non‑ABS where noted)
• Wagoneer 1990 export 9" brakes

What are the key specifications and hardware included?

The cylinder is constructed from cast iron and machined to accept brake line and bleeder components. It ships with the bleeder screw already installed but does not include a protective bleeder screw cap.

• Inside diameter (bore): 0.813 inch / 13/16"
• Brake component inlet thread: 3/8-24 (thread diameter 3/8")
• Material: cast iron for strength and wear resistance
• Includes bleeder screw; cap not included

How does this part meet durability and safety checks?

A-Premium subjects each cylinder to both pressure and thermal screening to help verify integrity and function before shipment. Those tests are intended to reveal leaks, casting flaws, or thermal weaknesses that could affect braking performance.

• Pressure-tested across a wide range (0.2 MPa to 20 MPa) to detect leaks or seal failures
• High-temperature exposure at 120°C to check material and seal stability
• Machined bores to precise tolerances for consistent piston movement

How do I confirm this is the right replacement for my vehicle?

Verify your vehicle year, model, and brake configuration before purchase — especially if your car has ABS or non‑standard export setups. Use the provided reference numbers or enter your vehicle information in the listing to cross-check fitment and special notes.

• Reference numbers include W37862, 82042, 4423601, 5252617 for cross-checking
• Confirm presence/absence of ABS and whether your rear brakes are 9" drums
• Compare bore size (13/16") and inlet thread (3/8-24) with the old cylinder

Who is this for: This A-Premium rear drum brake wheel cylinder suits professional mechanics and DIY enthusiasts replacing worn or leaking rear wheel cylinders on compatible Jeep, Dodge, Plymouth and Chrysler vehicles. It's appropriate for owners seeking a cast-iron, tested replacement that aligns with factory dimensions for rear driver and passenger side service.
