Compact 4-Piston Hydraulic Disc Brake Set for eBike and Mountain Bike

The internal routing of hydraulic disc brakes offers several advantages that enhance the overall bicycle experience. Aesthetically, it provides a cleaner and neater appearance by concealing cables and hoses within the frame, eliminating visual clutter on the exterior. Aerodynamically, internal routing contributes to reduced resistance, potentially offering minor performance benefits for cyclists seeking speed and aerodynamic efficiency.

Moreover, the protected nature of the lines within the frame helps safeguard them from external impacts, reducing the frequency of maintenance and cleaning. Waterproofing is also improved, as the enclosed lines are less susceptible to the impact of rainwater and humidity, minimizing the risk of water and dust infiltration.

From a safety perspective, hidden lines are less prone to being snagged by external objects, lowering the risk of accidents.

Introducing the ZTZ 4-Piston Internal Routing Hydraulic Brake Set, a powerful and efficient braking solution designed for mountain bikes and e-bikes. This upgraded brake system boasts several key features:

【Powerful 4-Piston Braking】The ZTZ hydraulic brake caliper is equipped with 4 oil pressure pistons, providing enhanced braking capacity and ensuring easier and safer braking performance.

【Quiet and Efficient】The integrated hydraulic cylinder prevents oil leakage, delivering a quiet braking experience. The resin-metal composite brake pads not only ensure quiet braking but also protect the bike's disc rotors.

【Optimal Hose Length】Ensuring a seamless installation, the front brake hose measures 850mm (33.4 inches), and the rear brake hose is 1600mm (63.0 inches).

【Effortless Installation】The pre-bled hydraulic brake kit uses mineral oil fluid, making it ready to install and use upon unboxing. Precautions should be taken to avoid squeezing the brake lever when the caliper is not clamped on the protective pad or brake rotor, to prevent oil leakage. The separated caliper hose and control lever facilitate easy internal routing.

【Universal Compatibility】These hydraulic disc brakes are suitable for a wide range of models, including electric ebikes, fat tire bikes, folding bikes, and scooters. They are compatible with popular models such as SHIMANO BR-M8120/M7120/M6120/M8020/M820/M810/M640MT520/MT420.

In conclusion, the internal routing of hydraulic disc brakes offers numerous advantages, from improved aesthetics and aerodynamics to enhanced protection and safety. The ZTZ 4-Piston Internal Routing Hydraulic Brake Set exemplifies these benefits, delivering a powerful and efficient braking solution for mountain bikes and e-bikes.
