Brake Master Cylinder 47207-37052 47207-37052 For Hino Dutro XZU427 4.0L Diesel

The Brake Master Cylinder Assembly with OEM number 47207-37052 (also listed as 4720737052) is a verified direct-fit replacement for Hino Dutro trucks, specifically the XZU427 chassis. Manufactured to OEM specifiions, this cylinder is the heart of the hydraulic braking system. It converts mechanical force from the brake pedal into hydraulic pressure, distributing it through the brake lines to activate the calipers for safe and controlled deceleration.

• Real Shop Test Data: Precision-engineered 27mm bore cylinder delivers consistent hydraulic pressure — verified against Hino OEM specifiions for XZU427 chassis.
• Proven Durability: Constructed from high-grade aluminium for superior corrosion resistance and heat dissipation — rated for 200,000+ km under normal operation.
• Installation Success Rate: 99% direct bolt-on fitment — confirmed across thousands of repair orders for Hino Dutro vehicles.
• OEM Cross-Reference Verified: Replaces 47207-37052 and compatible with DYNA/TOYOACE appliions.

If your brake master cylinder is failing, you may experience one or more of the following symptoms:

• Soft or Spongy Brake Pedal: Pedal feels unusually soft or slowly sinks to the floor — indies internal seal bypass.
• Sinking Pedal at Traffic Lights: Brake pedal continues to sink while held at a stop — a classic sign of failing internal seals.
• Increased Stopping Distance: Vehicle takes longer to stop than normal, even with firm pedal pressure.
• Brake Warning Light: Dashboard warning light illuminates with low fluid level and no visible external leaks.
• Fluid Leakage: Brake fluid seeping from the cylinder body or into the brake booster.

Our manufacturing and inspection processes ensure every brake master cylinder meets or exceeds Hino OEM standards.

• Bench bleed the new master cylinder before installation to remove air.
• Always use fresh DOT 3 or DOT 4 brake fluid from a sealed container.
• Inspect the brake lines and connections for damage or corrosion — replace if necessary.
• CRITICAL: Verify your vehicle is Left-Hand Drive (LHD) — this cylinder is for LHD vehicles only.

(Reference Hino workshop manual):

1. Disconnect the negative battery terminal.
2. Siphon old brake fluid from the reservoir.
3. Disconnect the brake lines from the master cylinder (note positions for reinstallation).
4. Remove the mounting nuts securing the master cylinder to the brake booster.
5. Remove the old master cylinder assembly.
6. Clean the booster mounting surface thoroughly.
7. CRITICAL: Bench bleed the new master cylinder:
   • Mount the cylinder in a vise
   • Fill the reservoir with fresh brake fluid
   • Slowly push the piston in and out using a blunt tool until air bubbles cease
8. Install the new master cylinder onto the booster.
9. Torque the mounting nuts to manufacturer's specified torque settings.
10. Reconnect the brake lines and torque to specifiion.
11. Refill the reservoir with fresh DOT 3 or DOT 4 brake fluid.
12. CRITICAL: Bleed the entire brake system in the correct sequence (starting with the wheel furthest from the master cylinder).
13. Test brake pedal feel and check for leaks before road test.

• Inspection: Every 50,000 km / 12 months. Check brake pedal feel, fluid level, and inspect for leaks.
• Fluid Replacement: Every 2 years or 40,000 km — replace brake fluid to prevent internal corrosion.
