GOIMGN Pit Bike Front Brake Assembly for 50–125cc — Dual-Piston Caliper, Aluminum Master Cylinder, Complete Kit

GOIMGN Pit Bike Front Brake Master Cylinder Caliper Assembly is a complete hydraulic front brake kit designed to replace or upgrade 50cc–125cc pit bike front brake systems with a durable aluminum alloy caliper, dual-piston performance, and included accessories.

Whether you're repairing a damaged front brake or upgrading to a more consistent hydraulic setup, this GOIMGN assembly gives you a ready-to-install option compatible with many common pit bike makes and models. It arrives as a full front-disc brake assembly with hose, switch, extra pads, and mounting straps to reduce parts hunting and installation time.

How does this brake assembly fit my 50cc–125cc pit bike?

The GOIMGN front brake assembly is engineered for broad compatibility with 50cc through 125cc pit bike front brake systems. Its mounting hole spacing and included hardware align with common industry standards, and the hose length suits typical front fork routing.

• Mounting hole spacing: 45 mm (1.77") for straightforward bolt alignment
• Brake hose length: 1100 mm (43.5") to reach standard front master cylinders
• Brake rod length: 220 mm (8.66") for lever connection and travel
• Compatible brands: SSR, TaoTao, Apollo, Coolster, Roketa, Jetmoto, Baja, and similar pit bikes

What braking performance can I expect on trails and street runs?

This assembly uses a dual-piston caliper and a hydraulic master to provide predictable lever feel and stronger stopping than many stock mechanical setups. The dual-piston design helps minimize air intake into the system, keeping braking consistent under repeated use on varied terrain.

• Dual-piston caliper for increased contact and even pad wear
• Hydraulic master cylinder for responsive lever modulation
• High-temperature, wear-resistant pads included to handle heat from repeated braking
• Suitable for both on-road and off-road riding where reliable front braking is needed

What materials and build details ensure durability?

GOIMGN constructed the caliper and master cylinder from aluminum alloy and steel to resist impact and corrosion common in off-road environments. The kit includes components chosen to withstand heat and abrasion, extending service intervals compared with softer materials.

• Caliper and master cylinder: aluminum alloy for strength and corrosion resistance
• Steel hardware where additional toughness and secure mounting are required
• Brake pads designed for high-temperature performance and reduced wear
• Sealed hydraulic connections to help keep contaminants out of the system

What comes in the box and how much installation work is involved?

The package arrives with the major parts needed to install a front hydraulic brake assembly, plus accessories that simplify mounting and connection. Basic mechanical skills and standard tools are typically all that's required; bleeding the hydraulic line is the final step to achieve full braking performance.

• 1 × front disc brake assembly (caliper + master cylinder + hose)
• 3 × mounting straps to secure hose and components
• 1 × extra brake pad for spare or replacement
• 1 × fuel filter (included as an accessory) and 1 × front brake light stop switch

Who is this for? The GOIMGN Front Brake Master Cylinder Caliper Assembly is aimed at pit bike owners, mechanics, and hobbyists who need a reliable, direct-fit hydraulic front brake replacement or upgrade for 50cc–125cc models. If you own an SSR, TaoTao, Apollo, Coolster, Roketa, Jetmoto, Baja, or similar pit bike and want stronger, more consistent front braking with durable components and included installation accessories, this kit is a practical choice. It suits riders wanting improved lever feel, workshop technicians needing a dependable aftermarket unit, and anyone looking to reduce downtime with a complete assembly that arrives ready for plumbing and bleeding into service.
