Product Introduction
A11-3502170 Brake shoe for Chery
Our brake shoes deliver durable friction performance for commercial and vintage vehicles. Featuring high-carbon steel crescent cores bonded with eco-friendly copper-free linings, they withstand 650°C extreme heat without cracking. The riveted + glued dual fixation ensures 100% bond integrity, while pre-tensioned return springs eliminate drag noise.
Product Advantage
1. Military grade composite lining technology
Adopting ceramic and aramid reinforced lining, the friction coefficient is stable at 0.40 ± 0.02, and the peak heat resistance reaches 650 ° C. Through a 28MPa shear strength test, the lining does not fall off during heavy load emergency braking. Dust emissions<1.0g/braking, wheel cleaning cycle extended by 200%.
2. Dual mode fixed anti detachment structure
Double anchoring with riveting and high-temperature epoxy adhesive, no looseness after 500000 impact tests. The backboard adopts 510L high carbon steel crescent core, which has an 80% increase in deformation resistance compared to ordinary steel core. Support heavy load conditions above 8T to eliminate the risk of lining displacement.
3. Global anti-corrosion coating
The zinc nickel alloy coating on the backboard has passed a 1000 hour salt spray test, and its corrosion resistance is three times that of galvanized products. Laser welded 304 stainless steel return spring seat, resistant to corrosion from seawater/deicing agents. Suitable for harsh environments such as mines/ports, with a lifespan of over 100000 kilometers.

Product Uses
Here are specific application scenarios of Brake shoe:
1. Commercial Trucks & Trailers
Brake shoes are critical for heavy-duty vehicles carrying substantial loads. Our high-friction linings withstand intense heat and pressure during long hauls or downhill braking, preventing brake fade. Ideal for freight trucks, dump trailers, and semi-trailers operating in mountainous or high-stress environments. Durable construction ensures reliable stopping power even with frequent stop-and-go traffic, reducing downtime for fleet operators.
2. Passenger Vehicles & Vintage Cars
Specifically engineered for drum brake systems in sedans, SUVs, and classic automobiles. Our brake shoes deliver smooth, low-noise braking for daily commutes and city driving. Compatible with popular models from Toyota, Ford, and Chevrolet. The eco-friendly asbestos-free formula minimizes dust buildup on wheels while maintaining consistent performance in wet or dry conditions – perfect for family safety.
3.Motorcycles & Recreational Vehicles
Lightweight yet robust brake shoes for scooters, ATVs, and side-by-side UTVs. Engineered to perform in sandy, rocky, or muddy trails without losing friction efficiency. Quick-recovery design maintains responsiveness during adventurous rides. Precisely curved for full drum contact, enhancing control on steep inclines. A must-have for adventure touring and off-road enthusiasts.
Product Operate Guide
Step 1: Safety First
Always work on level ground with parking brake engaged. Wear gloves and eye protection. Chock wheels opposite the repair axle. Never compress brake springs without proper tools – sudden release may cause injury. Allow hot brakes to cool completely before servicing (>30 mins after driving).
Step 2: Drum Removal
Loosen lug nuts, lift vehicle securely on jack stands. Remove wheel and locate drum retention screws (if equipped). Tap drum edges lightly with rubber mallet to break rust seal. Avoid prying – damaged drums cause uneven shoe contact. If drum sticks, retract adjuster through access hole.
Step 3: Shoe Replacement
Note spring positions with photos before disassembly. Use brake pliers to remove return/hold-down springs. Slide old shoes off anchor pins. Clean backing plate with brake cleaner – grease/dust reduces friction. Install new shoes in reverse order, ensuring linings face drum interior. Lubricate contact points with high-temp silicone (not on linings!).
Step 4: Adjustment & Testing
Turn star wheel adjuster until slight drag is felt when spinning drum. Reinstall wheels and lower vehicle. Pump brake pedal 3-5 times to seat shoes. Test drive at low speed (<30km/h), listening for scraping. Final adjustment occurs automatically during light reverse braking.
