What is included
Reference WG9112440001 suits Sinotruk HOWO (incl. HOWO A7, T7H), Sinotruk Steyr (STR), HOKA (08-model) heavy trucks at the Front axle – front wheel brake (fist-type, knuckle-type 6.5-ton front axle per Chinese supplier data; HOWO A7 front axles HF7, HF9 are drum-brake units per truck specification sheets). Order WG9112440001 and the numbers listed above travel on the same packing list, so one carton covers one reference.
Wear and fault symptoms
- Progressive wear of the friction surface (regular wear-out item; service shops are advised to stock ~1 unit per truck per year)
- Thermal, heat-check cracking and 'blue spots' from sustained heavy braking and long descents
- Brake fade from overheating – aggravated by incorrect cooling practice (e.g. spraying water on hot drums), which is explicitly listed as a replacement cause
- Out-of-round (ovality) and scoring of the friction surface causing pedal pulsation, judder and uneven braking
- Bell-mouthing, diameter exceeding the maximum machinable limit, requiring replacement rather than re-machining
- Hard spots and scoring leading to rapid brake lining wear and noise
Similar symptoms can come from neighbouring components, so inspect and test before replacing the part.
