How to Select Hydraulic Disc Brakes for Your Bicycle Project
Sending only a product photo is often not enough for accurate brake matching. Please also provide the bicycle type, original model, mount interface, rotor diameter, hose length, front or rear position and expected order quantity to avoid assembly risks.
Upload Your Brake Photo or Specification| Selection item | Buyer should confirm |
|---|---|
| Bicycle application | MTB, e-bike, road, city, kids’ bike |
| Brake position | Front, rear or complete set |
| Piston configuration | 2-piston, 4-piston or model-specific |
| Mounting interface | IS, Post Mount or Flat Mount |
| Rotor diameter | 140, 160, 180 or 203 mm |
| Lever design | 2, 3 or 4 finger |
| Lever orientation | Left/right configuration must be confirmed |
| Hose length | Provide required front and rear length |
| Brake fluid | Confirm by exact model |
| Brake pad | P08, P15 or model-specific |
| E-bike requirement | Sensor connector and control requirement |
| Special function | W2P connector or parking function |
| Packaging | Neutral, paired set or customized packaging |
| Quantity | Sample, trial order or bulk quantity |
How Do Bicycle Hydraulic Disc Brakes Work?
A bicycle hydraulic disc brake transfers pressure from the brake lever through fluid inside the hose. The pressure moves the caliper pistons, which press the brake pads against the rotor. Model selection depends on the caliper, lever, hose, fluid, pad, rotor and mounting interface working as one matched system.
2-Piston vs 4-Piston Hydraulic Disc Brakes
Conclusion: Do not select a brake only by piston count. Rotor diameter, mount type, lever design, hose length, fluid system, bicycle load and intended riding application must be reviewed together.
| Selection factor | 2-piston options | 4-piston options |
|---|---|---|
| Catalog applications | General MTB, e-bike, kids and selected systems | Selected MTB and e-bike models |
| TESNO examples | E800, E500, M500, M520, M200, M220, C220 | E860XP, E860, E620, M620, M600 |
| Rotor selection | Depends on model and application | Depends on model and application |
| Procurement decision | Confirm bicycle load and target configuration | Confirm bicycle load and target configuration |
| Important note | Piston count alone does not confirm full compatibility | Piston count alone does not confirm full compatibility |
Hydraulic vs Mechanical Disc Brakes
