NUTT Y5-D Four-Piston Hydraulic Disc Brake (Magnetic Cutoff)

Upgrade your electric vehicle's stopping power with the high-performance NUTT Y5-D Four-Piston Hydraulic Brake. Purpose-built for electric scooters, folding bikes, and lithium battery-powered bicycles, this robust aluminum alloy braking system utilizes mineral oil pressure to deliver superior, consistent braking.

Featuring an advanced 4-piston symmetric dual-drive system, it applies synchronized pressure from both sides of the rotor. This eliminates wobble, maintains perfect rotor alignment, and delivers up to twice the stopping power of standard brakes, ensuring linear deceleration and maximum safety on every ride.

Easy Installation (No Bleeding Required!): This hydraulic brake features a clever modular design where the brake lever and caliper assembly (with pre-filled hydraulic hose) are packaged separately. Simply connect the lever to the pre-bled hose for a hassle-free setup!

Flexible Routing: The oil pipe is designed to rotate 270 degrees, making complex cable routing on folding e-bikes and scooters incredibly easy.

Key Features

Quad-Piston Dual Drive: Dual-sided equal force eliminates rotor warp and provides immensely powerful, synchronized stopping capabilities.
E-Bike Magnetic Cutoff: Features a waterproof automatic magnetic cutoff connector to instantly disengage your electric motor when braking.
EM Resin Brake Pads: Equipped with a high-performance organic composite resin formula that reduces wear rate by 65% while maintaining consistent grip.
Premium Materials: Constructed with a high-strength aluminum alloy caliper and heavy-duty brake hoses for long-lasting durability.
