STAR UNION 220PYD Pro eBike Hydraulic Disc Brake Complete Kit
If your bike has mechanical disc brakes, the biggest upgrade you can make is switching to an eBike hydraulic disc brake system.
The STAR UNION 220PYD Pro is a complete 4-piston hydraulic brake upgrade kit designed for eBike riders looking for stronger braking performance. The kit includes front and rear hydraulic brakes, brake rotors, ceramic brake pads, and 2-pin motor cut-off connectors.
A slightly cheaper dual-piston version is also available.
The 4-piston calipers are designed to provide stronger and more stable braking than a standard 2-piston setup, making the system particularly suited to heavier eBikes, faster riding, or riders who want additional braking control.
The eBike hydraulic disc brake system comes pre-bled with mineral oil, which can simplify installation. The front brake uses a 1000mm hose while the rear brake has an 1800mm hose. Professional installation may be recommended if the hoses need to be shortened or the system requires bleeding.
The included 2-pin motor cut-off connectors are designed to interrupt motor power when a brake lever is activated. Riders should confirm that their eBike uses compatible 2-pin connectors before ordering.
The STAR UNION 220PYD Pro Complete Kit is priced at $130 and is available directly from StarUnion-store.com. The company states that most U.S. orders ship from its California warehouse with an estimated delivery time of 3–6 days. The product includes a 1-year warranty and a 30-day return policy.
