Key Advantages of Genuine Howo Brake Drum

Superior Heat Management

Optimized rib design and HT250 grade iron increase surface area, reducing peak temperature by 35% compared to generic drums.

Extended Lifespan

Our Howo Brake Drum lasts up to 200,000 km under normal highway conditions – 40% longer than aftermarket copies.

Precision Machined

Surface finish Ra ≤1.6μm, runout within 0.08mm ensures even contact with linings, eliminating vibration and noise.

Crack-Resistant Construction

Spheroidal graphite formation and strict chill control prevent thermal cracks, even under continuous downhill braking.

Main Categories: Front & Rear Howo Brake Drum

Front Brake Drum
Designed for front steering axles with balanced weight distribution. Typically smaller inner diameter (Φ410–420mm) and 8 mounting holes. Enhances steering stability and reduces unsprung mass.
Rear Brake Drum
Heavy-duty construction for drive axles. Larger diameter (Φ420–430mm) with reinforced ribs to withstand higher torque from parking brakes and retarding forces.

Authentic drums have a laser-etched part number, QR code, and casting mark “HOWO”. Weight should be within ±1kg of specification.

5. Does the Howo Brake Drum fit Steyr or Hanvan trucks?
Yes, for same-platform trucks with Howo axles (AC16, HC16). Verify your original part number before ordering.
6. What torque should be used for wheel nuts on a Howo Brake Drum?
Tighten to 450–500 Nm in a star pattern. Over-torquing may cause distortion or cracks around bolt holes.

Yes, 12 months or 100,000 km against manufacturing defects (excludes normal wear).

Troubleshooting Common Howo Brake Drum Issues

Brake pulsation / pedal vibration
→ Drum out-of-round (runout >0.20mm). Machine on a brake lathe or replace drum.
Blue spots / surface glazing
→ Overheating due to dragging linings or excessive use. Inspect slack adjusters and automatic brake adjusters.
Radial cracks between stud holes
→ Wheel nuts over-torqued or incorrect seating. Replace drum immediately and torque to 450-500 Nm.
Uneven lining wear (tapered)
→ Drum eccentric or axle spindle misalignment. Check runout, replace drum if needed.
