Product Description
OEM REPLACEMENT
Brake Vacuum Booster 1-47800413-0 for ISUZU FSR / FSR 500 (6HE1 Diesel)
Direct-fit OEM replacement brake vacuum booster with OEM number 1-47800413-0 (1478004130), engineered for ISUZU FSR / FSR 500 trucks equipped with the 6HE1 diesel engine. This booster is a critical component of the braking system, using engine vacuum to multiply pedal force and reduce the driver effort required to stop the vehicle safely. Cross-referenced as HDA-008 and MC828264 in aftermarket catalogs.
Verifiable Quality Signals
- Leak Tested Per Unit: Each booster undergoes vacuum leak testing before packaging to confirm diaphragm and housing integrity — verified via in-line test station with pass/fail record per production lot.
- Dimensional Verification: Mounting flange, pushrod length, and vacuum port orientation checked against OEM reference dimensions for ISUZU FSR 6HE1 application — CMM inspection on sampled units.
- Material Verification: Housing constructed from high-strength metal (aluminium/steel alloy) for corrosion resistance under engine-bay conditions — material certificates traceable per heat lot.
- OEM Cross-Reference: Replaces 1-47800413-0 / 1478004130. Also referenced as HDA-008 / MC828264 in aftermarket cross-reference systems (see compatibility note below).
⚠️ Critical Cross-Reference Notice: The HDA-008 / MC828264 numbering is primarily associated with Mitsubishi Fuso FK/FM series brake boosters in aftermarket catalogs. This product is offered as an ISUZU FSR 6HE1 fitment with these numbers listed as cross-reference aliases. If your application is a Mitsubishi Fuso truck, verify physical dimensions (pushrod length, mounting pattern) before ordering.
Failure Symptoms — When Replacement Is Due
- Hard brake pedal requiring excessive force to stop
- Hissing or whistling sound from under the dash when braking (vacuum leak)
- Engine idle changes or stalls when brake pedal is pressed
- Brake pedal feels spongy or does not return properly
- Visible corrosion or brake fluid leakage at the booster body

Vehicle Fitment
| Brand | Model | Engine Code | Notes |

| ISUZU | FSR / FSR 500 | 6HE1 | Primary fitment per OEM number |
| ISUZU | FVR / FTR | 6HE1 (verify) | Some cross-applications reported; confirm by VIN |
⚠️ Important Fitment Notes:
- HDA-008 / MC828264 are aftermarket cross-reference numbers, primarily appearing in Mitsubishi Fuso brake booster catalogs. This product is primarily adapted for ISUZU FSR 6HE1; the above numbers are listed for customer cross-comparison.
- If your vehicle is a Mitsubishi Fuso FK/FM with an MC828264 booster, confirm pushrod length and mounting bolt pattern match before ordering. "Short" vs "long" pushrod variants exist within the MC828264 family.
- Always provide VIN/chassis number for verification. Do not rely solely on cross-reference numbers.
Features & Benefits
| Feature | Benefit + Verification Signal |
|---|---|
| Vacuum leak tested per unit | Ensures reliable brake assist and prevents hissing/pedal hardness — verified via in-line vacuum decay test with pass/fail record. |
| OEM-matched mounting geometry | Direct bolt-on fitment without modification — verified by CMM dimensional check against OEM FSR 6HE1 reference. |
| Corrosion-resistant metal housing | Withstands engine-bay heat and moisture — material certification per heat lot available on request. |

Quality Control & Verification
| QC Item | Verification Method |
|---|---|
| Vacuum integrity / leak rate | 100% in-line vacuum decay test; pass/fail recorded per unit/lot |
| Mounting dimensions | CMM / gauge inspection on sampled units against OEM drawing |
| Pushrod length & alignment | Go/no-go gauge check per production batch |
| Housing material & hardness | Material certificate per heat lot; hardness spot-check |
| Visual defects (cracks, porosity) | 100% visual inspection under magnification |
| Packaging integrity | Carton drop/compression check per shipment sampling plan |
Installation & Maintenance Recommendations
⚠️ IMPORTANT: Brake booster replacement involves the hydraulic brake system. Air must be purged from the system after installation. Professional workshop installation is strongly recommended.
Installation Guidelines (Reference ISUZU FSR Workshop Manual)
- Disconnect battery negative terminal; locate booster under hood at firewall.
- Remove master cylinder from booster (do not disconnect brake lines if possible; support master cylinder aside).
- Disconnect vacuum hose from booster check valve.
- Remove clevis pin connecting booster pushrod to brake pedal arm (under dash).
- Unbolt booster from firewall (typically 4 nuts); remove booster.
- Transfer check valve and any fittings from old booster to new unit if not included.
- Install new booster in reverse order; torque firewall nuts to OEM spec (confirm in manual).
- Reconnect master cylinder; bleed brake system thoroughly per OEM procedure.
- Test pedal feel and vacuum assist before road test.
Maintenance Schedule
- Inspect vacuum hose and check valve every 40,000–60,000 km or during brake service.
- Replace booster if pedal hardness, hissing noise, or vacuum leak is confirmed and cannot be resolved by hose/valve replacement.
