About the Honda TRX350 FourTrax
Early FourTrax brake service, with separate routes for the Rancher 350 models.
Honda’s TRX350 name appears on early FourTrax ATVs and in searches for later Rancher 350 models. The early brake applications on this page use TRX350 without a Rancher suffix. FE, FM, TE and TM identify the later machines and lead to their own fuel, filter and brake service selections.
Match the brake part to its location
Front shoes, rear shoes, a front master-cylinder repair kit and a reservoir diaphragm all have linked TRX350 1986–1987 applications. Shoes work inside the drums; the cylinder kit services the hydraulic cylinder; the diaphragm seals beneath the reservoir cap. Use the part for the location being repaired.
Model and application differencesCompare your TRX350 repair options
| Model or repair | What to check |
|---|---|
| Early TRX350 brake repair | The featured front shoes, rear shoes and front master-cylinder kit list 1986–1987. Each needs to match its own brake position and fitted assembly. |
| Later Rancher 350 | FE, FM, TE and TM pages have specific later applications. A product labelled only TRX350 does not establish coverage for all four Rancher variants. |
| Reservoir or cylinder fault | A reservoir diaphragm seals beneath the cap. The internal master-cylinder kit services a different part of the hydraulic system; one cannot substitute for the other. |
Frame, engine and component markingsHonda TRX350 FourTrax identification
Use the complete frame/model identification and the correct market documentation. Identify a replacement engine, carburetor or front end separately from the frame.
- Read the full model and year; distinguish the early TRX350 from the later two-letter Rancher models.
- Confirm front or rear drum location and compare the existing shoes and hub.
- Check the actual master cylinder and reservoir if controls have been replaced.
A shared model prefix or similar appearance does not establish the model year or parts fitment.
