Rear Right Lower Brake Wheel Cylinder 47560-36210 4756036210 For TOYOTA Coaster HZB50 RZB40 RZB50 Dyna 200 Toyoace 14B 15B 1HZ — OEM Verified Direct Fit, 28.5mm Bore, Cast Iron, Rear RH Lower

47560-36210 / 4756036210 Rear Right Lower Brake Wheel Cylinder for TOYOTA Coaster HZB50 RZB40 RZB50, Dyna 200 BU100, and Toyoace 14B 15B 1HZ (1993–2003). Precision 28.5 mm bore, cast iron body, rear right lower (R.RH.A) position.

The Brake Wheel Cylinder with OEM numbers 47560-36210 / 4756036210 is a verified direct-fit replacement for TOYOTA Coaster buses and Dyna 200 / Toyoace light 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.

This cylinder is specifically the rear right lower (RH, Rear or Lower) position unit — designated R.RH.A in Toyota parts catalogs and aftermarket listings. It is designed for Coaster HZB50, RZB40, RZB50, and BB4# chassis families, as well as Dyna 200 BU100/BU200 series and Toyoace G25 applications from the mid-1990s through the early 2000s. It features a cast iron body with a 28.5 mm bore and is typically supplied without a bleeder screw in standard aftermarket configuration.

• ✓Bore Diameter Verified: 28.5 mm — ADVICS TecAlliance catalog confirms Bore Diameter [mm]: 28.5; Blue Print ADT34497 confirms Kolbendurchmesser [mm]: 28,5; BGF lists the unit as 1-1/8".
• ✓Position Verified: Rear Right Lower (RH, Rear or Lower / R.RH.A) — Toyota EPC catalog title confirms "FOR RH, REAR OR LOWER"; ADVICS confirms "Fitting Position: Rear Axle Right"; Brettstruck describes the unit as "RH RIGHT HAND RWD REARWARD"; BGF references "R.RA".
• ✓Material Verified: Cast Iron — ADVICS and Blue Print both confirm cast iron construction. Blue Print additionally specifies Grauguss (grey cast iron).
• ✓Thread Specification Verified: 1 × M10 × 1.0 — confirmed by ADVICS TecAlliance data.
• ✓Weight Reference: 1.230 kg (Blue Print ADT34497) / 1.28 kg (ADVICS wholesale listing) — weight varies by brand and packaging.
• ✓Bleeder Screw Configuration: BGF explicitly lists this unit as "W/O BLEEDER" (without bleeder screw) in standard aftermarket configuration. Confirm whether your application requires a bleeder-equipped variant.
• ✓OEM Cross-Reference Verified: Replaces 47560-36210, 47560-37081, 47560-37082. Aftermarket cross-references include ADVICS / AISIN WCT-065, Blue Print ADT34467 / ADT34497, TRW BWN739 / BWN859, JAPANPARTS CD-208, ASHIKA 65-02-202 / 65-02-208, JAPKO 65208, AW1253, BGF BWN739 / F026A02350, MDR MWC-2208D.
• ✓Vehicle Coverage Verified: Confirmed for Coaster (TRB5#, XZB5#, RZB4#, HZB5#, BZB5#, BB4#) 93–03, Dyna 200/300 (BU100, 200 series) 95–02, Toyoace G25, and Dyna 400 (XZU404).

• ⚠Brake fluid leak at the 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.

Confirmed Fitment Sources: BGF explicitly lists 47560-36210 for TOYOTA DYNA/DYNA-200/DYNA-300 BU100, 200 SERIES 15B-FT/15B-FTE 4.1L 95–02 and COASTER BUS (TRB5#, XZB5#, RZB4#, HZB5#, BZB5#, BB4#) 14B/1H-Z 3.7L 4.2L 93–03. Brettstruck confirms the same part number for Coaster HZB50 1993-7/1999, 1HZ 6-cyl 4.2L, with RH Right Hand RWD Rearward position. PartSouq lists the part under TOYOTA XZU404 HZB50.

• ⚠Position is the primary selection risk: This is the rear right lower (RH, Rear or Lower) cylinder. The front/upper position on the same side uses 47550-36210 — a different OEM number. Do not interchange forward and rearward cylinders — confirm the required position against the original unit.
• ⚠Bleeder screw: BGF confirms this unit is supplied without bleeder screw ("W/O BLEEDER") in standard aftermarket configuration. If your application requires a bleeder-equipped cylinder, confirm this explicitly at inquiry.
• ⚠Weight discrepancy: Reference weights range from 1.230 kg (Blue Print) to 1.28 kg (ADVICS) depending on brand and packaging. Confirm net weight at inquiry rather than relying on a single catalog figure.
• ⚠Coaster vs. Dyna/Toyoace: The same part number serves both bus and light-truck applications on related platforms. Confirm the chassis code and brake configuration before ordering.

1. Confirm position first: Verify that the replacement is the rear right lower (RH, Rear or Lower / R.RH.A) cylinder, not the front/upper counterpart (47550-36210). Compare the OEM number and physical orientation to the original unit.
2. Safety first: Park on level ground, engage parking brake, and chock front wheels. Wear safety glasses and gloves.
3. Remove wheel and drum: Loosen lug nuts, raise the vehicle, remove the wheel, and extract the brake drum. Inspect drum and shoes for wear.
4. Disconnect hydraulic line: Place a drain pan underneath, disconnect the brake line from the wheel cylinder, and plug the line immediately to prevent contamination.
5. Remove old cylinder: Unbolt the wheel cylinder from the backing plate. Note the orientation of the push rods and the rear/lower position for correct reassembly.
6. Clean mounting surface: Remove rust, dirt, and debris from the backing plate mounting area. Inspect the backing plate for damage or deformation.
7. Install new cylinder: Position the new wheel cylinder (47560-36210) onto the backing plate and tighten mounting bolts to specification.
8. Reconnect brake line: Connect the hydraulic line. Tighten to M10 × 1.0 thread specification without over-torquing.
9. Install shoes and drum: Reinstall brake shoes, adjuster components, and drum. Set shoe-to-drum clearance to the workshop manual specification.
10. Bleed the brake system: Fill the master cylinder reservoir with DOT 3 or DOT 4 brake fluid. Bleed until clear, bubble-free fluid flows. Note: This unit is frequently supplied WITHOUT a bleeder screw in standard aftermarket configuration — confirm your bleeding method or verify bleeder-equipped availability before installation.
11. Test brakes: Pump the pedal to seat the shoes, check for leaks, and road-test at low speed before returning the vehicle to service.

• Inspect wheel cylinders every 40,000–50,000 km or during any brake service.
• Replace wheel cylinders in axle pairs or position-matched pairs — mixing old and new cylinders on the same axle can cause uneven braking.
• Flush brake fluid every 2 years or according to manufacturer interval — contaminated fluid accelerates seal degradation.
• Inspect the backing plate for brake fluid wetness at every oil change — early detection prevents catastrophic seal failure.

• Standard packing: Individual box with protective packaging; wooden pallet available for bulk export orders.
• Package contents: 1 × Brake Wheel Cylinder (installation hardware not included; bleeder screw typically NOT included in standard configuration — confirm at inquiry).
• Set options: Single cylinder / rear RH pair (47550-36210 + 47560-36210) or full rear set (4 positions) — specify at inquiry.
• Suitable for: TOYOTA Coaster / Dyna / Toyoace brake system repair shops, bus fleet maintenance departments, spare parts distributors, and export wholesalers serving Southeast Asia, the Middle East, Africa, and Latin America.
• Related parts available: Paired counterparts 47550-36210 (RH front/upper), 47570-36210 (LH front/upper), 47580-36210 (LH rear/lower); brake shoes, brake drums, wheel cylinder repair kits, and brake fluid (DOT 3/DOT 4) for the Coaster/Dyna platform.
