SUNTES DB-3033AF SA Pneumatic Disc Brake
Customer: What is this product used for?
KAYO: The spring applies the brake or clamp and air pressure releases it.
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.

Customer: Are there important operating notes?
KAYO: Bed in new pads to obtain the required braking torque. The stated friction coefficients apply after bedding-in. Values in parentheses for pad friction refer to high-friction pads.
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.
