HOLATO Front Hydraulic Disc Brake Assembly for 50–125cc – 22mm Master Cylinder, Includes Pads

HOLATO's front hydraulic disc brake assembly is a ready-to-install master cylinder and caliper kit with pads designed to upgrade stopping power on 50cc–125cc Chinese dirt bikes and ATVs.

This complete front brake unit arrives assembled and trimmed to fit common small-frame pit bikes and utility ATVs, combining a 22mm (7/8") handlebar master cylinder, caliper, and two replacement brake pads. Built for bolt-on convenience, it replaces worn cable or less-powerful hydraulic systems on models such as TaoTao DB10/DB14, SSR110/SSR125, Apollo RZF, and many other 50cc–125cc machines. The kit includes the 1060mm oil line and mounting hardware details so you can confirm fitment before purchase.

Will this brake fit my bike or ATV?

Measure three key dimensions to confirm compatibility: handlebar clamp size, mounting hole spacing, and hose length. The HOLATO assembly is made for 22mm (7/8") handlebars, has a 43mm center-to-center mounting hole distance, and comes with a 1060mm (41.73") oil pipe.

• Handlebar clamp: 22mm (7/8")
• Mounting holes center-to-center: 43mm (1.69")
• Oil line length: 1060mm (41.73")
• Common fits: TaoTao, SSR, Apollo, SDG, Roketa, Lifan, Pitster Pro

How difficult is installation and what’s included?

The kit ships pre-assembled so you only need to bolt it on, bleed the line if required, and snug mounting fasteners. Basic hand tools and a short bleed are all that’s usually needed for a functional front brake upgrade.

• Included: 1 assembled front hydraulic brake unit
• Included: 2 brake pads and 4 cable ties for neat routing
• Tools: wrench set, bleeding kit recommended
• Time: typically 30–90 minutes depending on experience

What performance and maintenance should I expect?

This heavy-duty caliper and master cylinder deliver stronger, more consistent braking than worn drums or stretched cables, while replaceable pads make upkeep straightforward. Regular checks of pad thickness, fluid level, and hose routing keep the system working safely.

• Benefit: Improved stopping power over stock cable systems
• Service: Replace pads as they wear; check fluid periodically
• Durability: Designed for off-road and utility use
• Note: Inspect fit against original parts before ordering

Who is this for? Riders who own small-displacement Chinese or import dirt bikes and ATVs (50cc–125cc) and want an easy-to-install front hydraulic disc brake with factory-ready components. It’s ideal for weekend trail riders, kids’ pit bikes being upgraded for safety, backyard mechanics replacing worn systems, and small-vehicle fleets needing consistent braking. Before purchase, compare your bike’s handlebar diameter, caliper mount spacing, and hose routing to the listed measurements to ensure a smooth swap.
