Product Description
HINO 500 Rear Right Brake Wheel Cylinder 47550-2690 475502690
Verified OEM Direct-Fit 2-5/16" (58.7mm) for FG15T GH17T
Product Overview
This Brake Wheel Cylinder is a verified direct-fit replacement for the rear right side of HINO 500 series trucks, with OEM numbers 47550-2690 / 475502690 and a bore diameter of 2-5/16 inches (58.7mm). The wheel cylinder is a core hydraulic drum brake system component, mounted on the rear axle brake backing plate right side (RR-RH), pushing the brake shoes against the drum to achieve braking. Designed for HINO 500 FG15T and GH17T models, it offers bolt-on fitment without modification.
Working Principle
The brake wheel cylinder is the actuating element in a drum brake hydraulic system. When the driver depresses the brake pedal, the master cylinder pressurizes brake fluid, which is transmitted through hydraulic lines to each wheel cylinder. The pistons inside the wheel cylinder push outward under hydraulic pressure, forcing the brake shoes into contact with the rotating brake drum. Friction converts the vehicle's kinetic energy into heat, decelerating or stopping the vehicle. The piston cup seals are critical — if they age or rupture, brake fluid leaks, braking force drops, and total brake failure can result.
Failure Symptoms
- Brake pedal feels soft or spongy; pedal travel gradually increases with the pedal held down
- Vehicle pulls to one side under braking; insufficient right-side braking force
- Master cylinder reservoir fluid level drops rapidly; abnormal brake fluid consumption
- Visible brake fluid seepage around the wheel cylinder area
- Scraping or grinding noise during braking
These symptoms indicate that the wheel cylinder's piston seals have failed or the bore is worn. Prompt replacement is required to prevent total brake system failure.

Installation & Maintenance Recommendations
Critical Safety Advisory: Brake wheel cylinder replacement involves a core component of the hydraulic braking system and must be performed by a qualified technician. The brake system must be completely bled of air during installation; otherwise, brake failure will result.
Installation Guidelines (Reference Workshop Manual)
- Lift and safely support the vehicle; remove rear wheels and brake drum
- Disconnect the brake line connection; collect any leaking brake fluid
- Remove wheel cylinder mounting bolts; take out the old cylinder and clean the mounting surface
- Install the new cylinder; tighten mounting bolts to the torque specified in the workshop manual
- Reconnect the brake line, ensuring the fitting is secure
- Bleed the brake system until the pedal feels firm
- Reinstall brake drum and wheels; perform a road test to confirm normal braking performance
Always refer to the HINO 500 series original workshop manual for exact torque values.
Maintenance Schedule
- Every 6,000-12,000 km: Check brake fluid level and inspect wheel cylinder area for leakage
- Every 12 months or 60,000 km: Inspect wheel cylinder rubber seals; replace if necessary
- Every 2 years: Replace brake fluid to prevent moisture-induced internal corrosion
- If brake pedal feels soft, fluid level drops abnormally, or the vehicle pulls during braking, inspect the wheel cylinder immediately and replace
