This 4 piston motorcycle caliper is made of high-strength aviation-grade CNC aluminum alloy and designed with opposite different diameter pistons, providing excellent linear braking feedback and stable braking torque. It is the core first choice for upgrading the braking system of medium and large displacement motorcycles and accepts large orders.
The combination of 30mm and 34mm reduced-diameter pistons is used to make the brake pads more evenly stressed through the principle of pressure difference compensation, and the initial response sensitivity of braking is increased by 15%, effectively shortening the emergency braking distance.
the whole is made of 6061-T6 aluminum alloy through five-axis CNC precision machining, and the tolerance is strictly controlled within ± 0.02mm, ensuring that the piston operation is free of stuck, returning quickly, and significantly improving the driving control feeling.
special heat dissipation fins are designed on the surface of the shell, and combined with the hard anodic oxidation process, the temperature rise rate of the caliper under high-frequency braking is reduced by 20%, and the braking force caused by thermal attenuation is completely solved.
The internal sealing ring is made of high-performance EPDM rubber, which is corrosion-resistant and has a temperature range of -40 ℃ to 150 ℃. It can maintain 50,000 reciprocating movements without leakage under high pressure conditions.
Through the structural topology optimization design, the weight of a single caliper is controlled at about 800g, which reduces the weight by 30% compared with traditional cast iron calipers, effectively improving the reaction speed of the suspension system and the vehicle’s cornering flexibility.
equipped with quick-release brake pad fixing pins, brake pad replacement can be completed within 2 minutes without disassembling the entire 4 piston motorcycle caliper body, greatly reducing maintenance costs for end users.

Compared with the common cast two-piston or ordinary four-piston products on the market, this 4 piston motorcycle caliper adopts a higher-specification opposite diameter design, which solves the “brake nod” and strength that traditional calipers are prone to produce during high-speed braking. Uneven phenomenon. The hydrodynamic optimization of the internal oil passage reduces the pressure loss during hydraulic transmission by 12%, ensuring clear and solid feedback every time the brake lever is pinched.
In view of the sharp noise generated during braking, the high-precision piston centering design ensures that the brake pads and the disc are in complete parallel contact, which solves the vibration and abnormal noise caused by uneven force.
For long downhill or high-intensity use scenarios on the track, the rigidity and heat dissipation efficiency of the metal shell are strengthened, and the feel becomes empty and the braking force disappears due to overheating and expansion of the oil.
in view of the pain point of confusion in the modification market, a standard 40mm/100mm interface is provided and a high compatibility adapter is reserved, thus solving the problem that the front shock absorber and caliper of different models cannot be matched without loss.
This product is a standard performance upgrade for locomotives with a displacement of more than 400cc, with extremely high brand substitution and profit margins, and is suitable as a core item for channel volume.
For riders who pursue extreme performance, the linear strength and heat resistance of this product can meet the stringent requirements of frequent and vigorous braking, helping to improve the accuracy of cornering operations.
CNC’s exquisite cutting appearance and multi-color anodizing selection can meet the dual pursuit of customized modification customers for visual texture and hardware performance, and improve the grade of vehicle modification.
For long-distance riders who pay attention to safety and stability, the durability and low maintenance requirements of this product can effectively reduce the risk of failure during the journey and ensure long-term braking safety.
Our factory
A: In order to obtain the best feedback, it is recommended to cooperate with a direct push pump with a piston diameter of 15mm or 17mm to ensure that sufficient push oil is provided.
A: The piston is made of hard anodized aluminum alloy or stainless steel (according to the model), which has strong anti-corrosion performance and will not rust and cause stuck in a humid environment.
A: It is necessary to confirm the installation hole distance of the original car. If the hole distance is inconsistent, only need to match the corresponding adapter bracket (Adapter) to achieve non-destructive installation.
A: Yes, a pair of high-performance sintered metal brake pads are standard by default, which have excellent grip and high temperature resistance.
A: Please check whether the air in the oil circuit is completely drained; secondly, the new brake pads need a certain running-in period to achieve the best braking friction.
A: As long as the thickness of the disc is between 4.0mm and 5.5mm. Disc diameter depends on your installation code position, usually suitable for 260mm-320mm disc.
