SINOTRUK Howo Light Truck Front Brake Air Chamber Assembly SPCS0000000627
Chamber Type: Single Diaphragm Chamber. Since the front axle brake chamber is responsible only for service braking (foot brake) and does not participate in parking braking (spring brake/handbrake), it lacks a heavy-duty spring and features a purely pneumatic, single-diaphragm design.
Operational logic: When the brake pedal is depressed, compressed air enters through the inlet, pushing open the internal diaphragm and overcoming the resistance of the return spring to drive the pushrod forward; this action subsequently actuates the camshaft adjustment arm to spread the brake shoes.
Bill of Materials (BOM) for Front Brake Air Chamber (SPCS0000000627) Replacement
| No. | Part / Material Name | Specification / Core Parameters | Recommended Brand / Source | Qty | Unit | Replacement Remarks & Function |
|---|---|---|---|---|---|---|
| 1 | Front Brake Air Chamber | SPCS0000000627 (Single Diaphragm) | Sinotruk Light Truck Genuine (Qinren Parts) | 2 | pcs | Core Component. It is highly recommended to replace them in pairs (left & right) to ensure balanced and symmetric braking force on the front axle. |
| 2 | Pushrod U-Clevis | Matches M16×1.5 thread (includes lock nut) | Included with chamber / Genuine hardware | 2 | pcs | Mandatory Replacement. Connects the chamber pushrod to the slack adjuster. Worn pin holes in old clevises cause brake pedal free-play. |
| 3 | Clevis Pin & Cotter Pin | Specialized clevis pin + Stainless steel cotter pin | Included with chamber / Chassis accessories | 2 | sets | Mandatory Replacement. High-frequency load-bearing pivot pins. Thinned/worn pins cause mechanical lags during braking. |
| 4 | Air Line Copper Washers | Specialized pure copper crush washers for ID Φ16mm | Included with air lines / Universal repair kit | 4 | pcs | Mandatory Replacement. The high-pressure brake air circuit allows absolutely zero micro-leakage. Do not reuse old copper washers. |
| 5 | Air Line Quick Connector | M16×1.5 thread to Φ8mm or Φ10mm nylon hose push-in | RELI / Chuangfeinuo | 2 | pcs | Recommended Replacement. Front air lines flex repeatedly during wheel steering; new push-in joints prevent leakage at the pivoting stress points. |
| 6 | High-Pressure Brake Hose | Φ8mm or Φ10mm specialized black nylon air line | RELI / Universal commercial vehicle supplies | 1~2 | m | Replace as Needed. If the old nylon tube shows any signs of surface cracking, abrasion, or weathering, cut and replace it for safety. |
