SINOTRUK LIGHT TRUCK REAR BRIAGE Brake Shoe with Lining Assembly QT863D2-3502051
Brake Core & Friction System (Standard Quantities Per Axle / Both Sides)
| No. | Part Number / Spec | Part Name | Standard Qty / Axle | Key Technical Parameters & Maintenance Notes |
|---|---|---|---|---|
| 1.1 | QT863D2-3502051 | Rear Brake Shoe with Lining Assembly | 4 pcs | Core Replacement Item. Φ410×220mm, high-strength stamped-and-welded steel structure paired with premium non-asbestos friction linings. Requires 4 pcs per axle (left and right wheels). |
| 1.2 | WG9231342006 (Reference) | Heavy-Duty Brake Drum | 2 pcs | The friction counterpart mating with the brake shoe. If the old drum interior shows deep scoring, ridges, or cracks, it must be machined or replaced; otherwise, the new lining won't seat properly, resulting in a soft brake pedal. |
| 1.3 | 220mm Width Standard | Brake Lining Dust Caps / Rubber Plugs | 4 pcs | Small plastic/rubber plugs fitted on the brake backing plate. Protects the internal drum mechanism from mud, dust, and debris. Prone to cracking during removal; replacing with new ones is highly recommended. |
Fasteners & Return Spring Repair Kit (Core Items to Prevent Brake Drag & Lockups)
| No. | Part Number / Spec | Part Name | Standard Qty / Axle | Key Technical Parameters & Maintenance Notes |
|---|---|---|---|---|
| 2.1 | DZ9112340062 (Reference) | Brake Shoe Heavy-Duty Return Spring | 4 pcs | High-frequency wear item. Forces the brake shoe to retract completely when the brake pedal is released. Weak tension causes the lining to drag against the drum, inducing high-temperature friction, wheel lockups, or even tire fires. |
| 2.2 | DZ9112340063 (Reference) | Brake Shoe Anchor Pin Positioning Spring | 4 pcs | Small tension/torsion spring for lateral shoe alignment, preventing the brake shoes from shifting sideways under severe road vibrations. |
| 2.3 | Hande Axle Matched | Brake Shoe Rollers & Anchor Pins | 4 sets | Heavy-duty steel rollers and pins located at the shoe tips that interface directly with the S-camshaft. High-impact zone; if surface ridges develop, the brake return will jam. Replace and apply high-temperature grease. |
| 2.4 | Standard Hardware | Anchor Bushings & Snap Rings / Circlips | 1 lot | Fastening circlips used to lock the anchor pins and rollers. Deforms and becomes obsolete upon removal; classified as single-use mandatory replacement items. |
Actuation & Automatic Slacks Diagnostic Items (Recommended Maintenance/Upgrade Items)
| No. | Part Number / Spec | Part Name | Standard Qty / Axle | Key Technical Parameters & Maintenance Notes |
|---|---|---|---|---|
| 3.1 | DZ9100340056 (Reference) | Automatic Slack Adjuster Assembly | 2 pcs | Automatically calibrates brake clearance based on lining wear. If its internal worm gear jams or fails, the new brake shoes won't auto-tighten or will develop excessive clearance, causing single-sided brake failure. |
| 3.2 | DZ9100340010 (Reference) | S-Type Brake Camshaft (Left/Right) | 1 set | Rotating camshaft that pushes the brake shoes open. Focus on checking for wear at the cam head (S-profile working surface) and journal; excessive clearance reduces braking torque. |
| 3.3 | Type 30/30 Heavy Duty | Rear Axle Spring Brake Chamber (Actuator) | 2 pcs | The power source pushing the slack adjuster. Test the internal diaphragm for air leaks and the internal heavy-duty spring for breakage during shoe replacement to guarantee proper pneumatic thrust. |
