Compared With the Alternatives
| MITSUBISHI FUSO dealer original switch | Same fitment and thread size at aftermarket pricing, but without the dealer part number on the box unless you order branded packaging |
|---|---|
| Universal brake switch with metric thread | The NPT1/4 thread matches the original MITSUBISHI FUSO specification; a metric thread version would require an adapter and risk leakage |
| Used or reclaimed switch | New units carry a 12 month warranty from B/L date; reclaimed stock carries none and may have worn contacts |
Use Guide
- Confirm the vehicle is a MITSUBISHI FUSO with a mechanical brake pedal system before fitting
- Match the NPT1/4 thread and 29mm spanner size against the old switch before ordering
- Isolate the battery, remove the old switch from the brake pedal housing, and install the replacement with the sealing ring in place
- Test brake light operation at the pedal and verify the switch returns to OFF-ON state when released
- If the brake lights remain on, check the pedal linkage and switch mounting for binding before condemning the unit
