SUNTES DB-2050 Hydraulic Disc Brake

Customer: What is this product used for?
KAYO: Compare the disc size and operating conditions with the values below to select the correct SUNTES hydraulic or pneumatic disc brake.
Customer: Which specifications should I compare?
KAYO: Check the model-specific values below. Where a group has several variants, each column or row retains its own configuration. Lettered dimensions refer to the matching product drawing; a blank or dash does not state a value.

| Required fluid volume (cm3) | 7.0 | 10.0 |
| Applicable disc outside diameter (mm) | φ380–500 | |
| Disc thickness (mm) | 38.0 | |
| Effective braking radius (m) | r = ((Disc diameter)/2 -37 ) / 1000 | |
| Pad model | DB-0401 | |
| Usable pad wear allowance (mm) | 18.0 | |
| Pad friction coefficient (μ) | Dynamic: 0.3 Static: 0.15※2 | |
| Operating fluid | Brake fluid (DOT3 equivalent) or Mineral oil (ISO VG32 equivalent) | |
| Mass (kg) | 17.5 | |

Customer: Are there important operating notes?
KAYO: The minimum operating pressure is a reference value and can vary with individual sliding resistance. Bed in new pads to obtain the required braking torque. The stated friction coefficients apply after bedding-in.
Customer: How do I choose the correct version?
KAYO: Match the complete model, disc dimensions, mounting arrangement and operating duty. Check the required torque, speed, control pressure or electrical supply against the actual application.
Customer: What should I send for an enquiry?
KAYO: Send the model or nameplate photo, quantity, existing drawing, installation dimensions and operating conditions. For a replacement part, include the full brake or clamper code and photos of the existing component so that fit and configuration can be checked.
