Rear Right Brake Wheel Cylinder MC894285 MC112232 For MITSUBISHI Fuso Canter FB308 FB409 FB511 FE635 — OEM Verified Direct Fit, 1-1/8" Bore Cast Iron, Rear RH, Without Bleeder

MC894285 MC112232 Rear Right Brake Wheel Cylinder for MITSUBISHI Fuso Canter FB308 FB409 FB511 FE635 1992-1996 — 1-1/8" Bore without Bleeder, Verified OEM Fit

✅ Product Description

The Rear Right Brake Wheel Cylinder with OEM numbers MC894285 / MC112232 is a verified direct-fit replacement for MITSUBISHI Fuso Canter series trucks. This wheel cylinder is a critical hydraulic component of the rear drum brake system, responsible for converting hydraulic pressure from the master cylinder into mechanical force that pushes the brake shoes against the drum to slow or stop the vehicle.

The MC894285 is specifically designed for the rear right (passenger side) position on MITSUBISHI Fuso Canter models from 1992 through 1996 (and covering broader applications into the late 1990s for certain chassis), including the core chassis families FB308, FB409, FB511, and FE635. It is the paired counterpart to the rear left wheel cylinder MC894282 family. This unit is a manual-adjust type and is supplied without a bleeder screw (без прокачки) in its standard OE configuration.

This cylinder is manufactured from cast iron with a precision-honed 1-1/8" (28.58 mm) bore, and features a 32 mm mounting diameter with M10 × 1.0 thread.-1

✅ [Failure Symptoms — When to Replace]

• Brake fluid leak at wheel: Visible wetness around the backing plate or inside the brake drum — indicates seal failure and imminent braking loss.

• Spongy or long-travel brake pedal: Pedal sinks further than normal and feels soft — air enters the system through a failed seal, reducing hydraulic pressure.

• Uneven braking or vehicle pull: Vehicle pulls to one side during braking — one wheel cylinder is not applying equal force, causing imbalance.

• Brake fade or overheating drums: Extended stopping distances and hot brake drums — a failing cylinder may cause dragging or insufficient shoe application.

• Brake warning light illumination: Dashboard brake warning activates, often accompanied by abnormal brake behavior — inspect wheel cylinder immediately.

⚠️ Consequence of Ignoring Symptoms: A leaking wheel cylinder can lead to fluid loss, overheated drums, damaged brake shoes and drum surfaces, and in severe cases, complete loss of braking on one rear wheel — creating a critical safety hazard for loaded commercial vehicles.

⚠️ Important Fitment Notes:

• Position: This is the rear right (RH) wheel cylinder. The paired rear left counterpart uses OEM MC894282 / MC112229 and must be ordered separately if replacing both sides.

• Bleeder Configuration: This unit is confirmed without a bleeder screw (без прокачки) in its standard configuration. If your application requires a bleeder screw, verify with the supplier or consider a variant that includes one.

• Adjuster Type: This is a manual-adjust cylinder. Do not attempt to fit it to a vehicle requiring an auto-adjust cylinder without confirming compatibility.

• MC112232 vs. MC894285: These two OEM numbers are highly cross-referenced and are treated as interchangeable in the aftermarket. Always verify against the original unit or chassis plate.

• Replace in axle pairs: Industry best practice recommends replacing both left and right wheel cylinders simultaneously to ensure balanced braking performance.

✅ Features & Benefits

✅ Quality Control & Verification

Each unit undergoes 100% pressure testing before packaging. Manufacturing conforms to OEM specification standards for hydraulic brake components.

✅ Installation & Maintenance Recommendations

⚠️ IMPORTANT: Brake system service requires professional expertise. Always refer to the MITSUBISHI Fuso Canter workshop manual for complete specifications. Improper installation can result in brake failure and serious injury. Brake fluid is corrosive — avoid contact with painted surfaces.

Installation Guidelines (Reference Only):

1. Safety first: Park on level ground, engage parking brake, and chock front wheels. Wear safety glasses and gloves.

2. Remove wheel and drum: Loosen lug nuts, raise the vehicle, remove the wheel, and extract the brake drum. Inspect drum and shoes for wear.

3. Disconnect hydraulic line: Place a drain pan underneath, disconnect the brake line from the wheel cylinder, and plug the line to prevent contamination.

4. Remove old cylinder: Unbolt the wheel cylinder from the backing plate. Note the orientation of the push rods and spring positions.

5. Clean mounting surface: Remove rust, dirt, and debris from the backing plate mounting area.

6. Install new cylinder: Position the new wheel cylinder (MC894285) onto the backing plate and tighten mounting bolts to specification.

7. Reconnect brake line: Connect the hydraulic line. Tighten to M10 × 1.0 thread specification without over-torquing.

8. Install shoes and drum: Reinstall brake shoes, adjuster components, and drum. Set shoe-to-drum clearance per manual. This cylinder uses manual adjustment — perform the adjustment procedure per the workshop manual.

9. Bleed the brake system: Fill the master cylinder reservoir with DOT 3 or DOT 4 brake fluid. Bleed until clear, bubble-free fluid flows from the bleeder screw. Note: This unit is supplied without a bleeder screw in its standard configuration — ensure your bleeding method is compatible, or confirm with the supplier if a bleeder-equipped variant is required.

10. Test brakes: Pump the pedal to seat the shoes, check for leaks, and road-test at low speed before returning the vehicle to service.

Maintenance Schedule:

• Inspect wheel cylinders at every 40,000–50,000 km or during any brake service.

• Replace wheel cylinders in axle pairs — replacing only one side can cause uneven braking and pull to one side.

• Flush brake fluid every 2 years or according to manufacturer interval.

• Inspect the backing plate for brake fluid wetness at every oil change — early detection prevents catastrophic seal failure.
