The WG4005455501 Brake Lining Front represents the pinnacle of original‑equipment chassis safety for SINOTRUK HOWO trucks. As an integral part of our premium Sinotruk howo parts collection, this OEM WG4005455501 front lining is engineered to deliver consistent deceleration, thermal endurance, and structural integrity. Every component is 100% dyno‑tested and certified to meet the exacting standards of HOWO’s global heavy‑duty lineup.
The WG4005455501 front brake lining is not merely a consumable — it is a tuned chassis component that directly influences steering precision and emergency stopping distance. Unlike universal replacements, this OEM part features an arc radius machined to match HOWO’s specific drum curvature, achieving 85% contact area from the first brake application.
SINOTRUK HOWO engineers spent over 36 months developing the friction couple between Brake Lining Front and the cast‑iron drum. The result is a linear pressure‑to‑torque response that gives drivers confident modulation, even under 60‑ton gross loads. This is chassis engineering that prioritizes predictability.
Hybrid fiber matrix – Brake Lining Front combines aramid pulp, ceramic wool, and sustainable cellulose. This trio provides high‑temperature film strength without scoring drums. Zero copper, lead, or asbestos.
Scorch‑resistant resin – Phenolic resin modified with nitrile rubber cures at 220°C. WG4005455501 resists fade even after 500 consecutive downhill stops.
Density optimization – 2.12 g/cm³ uniform density eliminates shear‑induced cracks. Every Brake Lining Front lining is hot‑pressed at 350 bar.
CNC‑ground profile – Tolerance ±0.2 mm. Chamfers and slots are pre‑cut to suppress noise and eject dust.
1. Preparation – Lift truck, remove wheel and drum. Clean shoe table with wire brush. Inspect drum diameter.
2. Rivet / Bond – Use OEM rivets (included). Hydraulic press recommended. Brake Lining Front hole pattern matches OE.
3. Lubrication – Apply thin coat of high‑temp copper paste on shoe contact pads (avoid friction surface).
4. Reassembly – Mount drum, adjust slack adjuster. Torque wheel nuts to 550 Nm.
6. Check – After 100 km, re‑torque U‑bolts and inspect lining contact.
Thermal underrun – Brake Lining Front transfers 22% less heat to brake fluid, extending seal life.
Response time – 0.12s lag (pneumatic to torque), 15% faster than generic linings.
Drum friendliness – Polished wear surface reduces micro‑cracks; drum life +30%.
Green manufacturing – 94% water recycling, zero heavy metals, EU 2020/1070 compliant.
Instant bite – Factory‑scorched surface, 90% friction from first stop.
Cold performance – μ >0.35 at –30°C, no glazing.
🕒 Dyno test – 800 hours continuous, equivalent to 450,000 km. Wear rate 0.29 cm³/MJ.
💧 Salt spray – 96h, no corrosion or delamination (ISO 9227).
⚡ Shear after heat – 300°C for 2h, still ≥5.8 MPa bond strength.
📉 Compressibility stability – after 200k cycles, increase <0.3%.
Inspect every 50,000 km or annually. Use drum inspection slot to measure remaining thickness of Brake Lining Front.
Visual cues: even wear pattern, no cracks, no oil soak. Replace if thickness ≤8.0 mm.
Always replace both front wheels simultaneously. Keep axle alignment.
Store in original packaging, cool dry place. WG4005455501 shelf life 5 years.
❌ Fake linings often use asbestos or steel wool, causing drum scoring and illegal emissions. Brake Lining Front contains zero metal fibers.
❌ Imitations have loose thickness tolerances – up to 1.5mm undersize → brake lag. WG4005455501 is precision ground to ±0.2mm.
❌ No ECE R90 mark → illegal for on‑road use in 120 countries. Brake Lining Front displays holographic approval label.
Brake Lining Front is certified for sale in EU, Russia, South America, Africa, and ASEAN. Each lining carries ECE R90‑0396, GB 5763‑2018, and ISO 15484 marks.
Regional stock in Jinan, Dubai, Moscow, and Panama. Batch traceable via 2D Data Matrix on the lining edge.
Q: What is the average lifespan of Brake Lining Front? A: 180,000–220,000 km highway; severe service 120,000 km.
Q: Can I use Brake Lining Front with aftermarket drums? A: Yes, but optimal performance with genuine HOWO drums (OEM AZ9633320011).
Q: Does Brake Lining Front fit HOWO A7 2015? A: Yes, all A7 front axles use the same lining.
Q: How to distinguish genuine Brake Lining Front? A: Laser‑etched OEM number, smooth dark‑grey surface, no glitter, and hologram sticker.
Q: Is bedding required after installation? A: Yes, 30 moderate stops. WG4005455501 is pre‑scorched but still needs transfer layer.
Q: What is the difference between Brake Lining Front and WG4005455500? A: 5501 is front lining (different arc, thickness); 5500 is rear.
Q: Does Brake Lining Front contain copper? A: Zero copper, meets NAO standard.
Each Brake Lining Front lining is accompanied by a certificate of conformance, referencing the exact batch number. Warranty claims are processed within 48 hours.
SINOTRUK HOWO’s green initiative: Brake Lining Front is produced in a zero‑liquid‑discharge plant. Scrap linings are repurposed into industrial fillers.
Independent tests (TÜV Rheinland) show that WG4005455501 maintains μ between 0.38–0.42 from 100°C to 400°C. Cheap alternatives drop below 0.30 at 300°C, leading to dangerous fade. The proprietary resin in Brake Lining Front resists thermal decomposition, ensuring stable output even during alpine descents.
“We switched 40 HOWO trucks to WG4005455501. Brake‑related downtime dropped 37%.” – Lima Transport, Peru
“After 200,000 km, the Brake Lining Front linings still had 11mm left. Drums looked like new.” – Dubai Logistics
