Why Choose ZOOM Hydraulic Disc Brakes?

ZOOM's hydraulic disc brake system uses sealed oil-pressure lines for smooth, modulated braking that mechanical brakes simply can't match. The integrated molding oil cylinder reduces the risk of leaks, while the pre-filled mineral oil lines mean the brake levers are ready to install right out of the box — saving you setup time.

⚠️ Important Installation Notes

Please read before installing:

Do NOT press the brake lever before or during installation. Doing so may cause oil leakage, which would require the system to be refilled with mineral oil. Only press the lever once the brake is fully installed — the oil will then flow from the lever through the oil pipe into the caliper.
Do NOT remove the mold block (brake pad protection block) inside the caliper before the brake is fully installed. Removing it prematurely can cause the piston to shift, potentially resulting in oil leakage or the brake piston failing to rebound correctly.

SKU Note: This listing includes three SKU configurations — Front Only, Rear Only, and Front + Rear. Please verify your selected SKU before ordering to ensure you receive the correct configuration.

Frequently Asked Questions

Q: Is the ZOOM HB775E hydraulic disc brake set compatible with my e-bike or scooter?

A: Yes! The ZOOM HB775E hydraulic disc brake set is designed for a wide range of bikes including mountain bikes, e-bikes, electric scooters, folding bikes, and BMX cycles. It supports 160mm and 180mm rotors with standard IS and post-mount adapter compatibility (F160-R140 / F180-R160 or IS-A 180mm).

Q: Does this hydraulic brake set come pre-filled with oil?

A: Yes — the brake levers come pre-filled with mineral oil. Simply follow the installation instructions carefully: do not press the lever before the system is fully installed, and do not remove the caliper's mold block prematurely. Once installed, pressing the lever sends oil through the hydraulic line into the caliper.

A: This listing offers three SKU configurations: Front brake only (1100mm hose), Rear brake only (1850mm hose), or a complete Front + Rear set. Please confirm your selected SKU at checkout to ensure you receive the correct configuration for your build.

Q: What is the weight of the ZOOM HB775E brake set?

A: The brake set weighs approximately 740g without the rotor. Rotors are not included and must be purchased separately if needed.
