No oil pipes, so there's no risk of oil leaks. No need to change oil and refuel! Conversion Seats: The ZOOM HB-100 is equipped with conversion seats on both the front and rear, allowing for direct installation on A/B column front forks for more convenient installation. R = 140, F = 160 Note: Do not remove the yellow pads or pinch the brake lever before installation. Failure to do so will result in oil leaks and the oil disc will be discarded, making the brakes less sensitive. Package Contents: 2 x Brake Calipers (Front & Rear) 2 x Brake Pads (Pre-Installed) Bicycle Brake: One-piece, oil-resistant disc brakes use standard mineral-specific bicycle oil. There's no oil pipe, so oil leaks won't occur due to cracks. No need to change or refill the oil!

Durability: Upgraded hydraulic brakes provide powerful braking power, even after break-in, for fast and effective bike control.

Easy Installation: The ZOOM HB-100 features front and rear transfer bases for A/B column front forks. Direct installation is more convenient. Please refer to the installation photos.

Note: Suitable for upgrading line-pull mechanical clamp brakes. (Note: Do not remove the yellow pads or pinch the brake lever before installation, as this will result in oil leaks.)

Unprofessional technicians should not open the cylinder threads freely to prevent oil or gas leaks that could dull the brakes.
