This Rear Brake Caliper for Motorcycle adopts high-strength aluminum alloy and double-piston opposed structure, ensures 0.02mm fit tolerance through precision CNC machining, provides excellent heat dissipation performance and linear brake feedback, is the core guarantee for upgrading and maintenance of motorcycle brake system, and undertakes wholesale business.
ADC12 high performance die casting aluminum
Cylinder block material:
32mm/34mm double opposed piston
Piston specifications:
hard anodic oxidation treatment
Surface process:
the shell adopts CNC cutting technology with 0.02mm precision to ensure that the piston cavity cylindricity error is extremely low, significantly reduce the wear of the sealing ring and prevent oil leakage, and extend the service life by more than 40%.
Compared with the single-piston structure, the dual-piston opposed provides a more balanced clamping pressure, which makes the brake pads wear more evenly, shortens the braking distance by about 15%, and improves driving safety.
The shell is designed with 30% additional surface area heat dissipation fins, which effectively reduces the oil temperature under continuous braking, prevents brake thermal degradation, and ensures constant pressure under extreme working conditions.
The internal seal is made of ethylene propylene diene monomer (EPDM), which can withstand instantaneous high temperature up to 200 ℃, ensuring that the brake fluid does not leak any trace under extreme pressure.
follow the industry general standard 84mm hole distance, adapt to more than 90% of the world’s small and medium-displacement motorcycle rear brake bracket, greatly reduce the installation difficulty and adaptation cost.
the surface after 120 hours of salt spray test, even in the coastal wet environment or winter sprinkling salt road, can maintain more than 3 years without oxidation spots and rust stuck.

Our Rear Brake Caliper for Motorcycle adopts a racing-grade lightweight design, and the overall weight is reduced by 35% compared with traditional cast iron calipers, which effectively reduces the unsprung mass and makes the vehicle suspension system more responsive. At the same time, the inside of the runner is optimized by fluid mechanics, and the filling speed is increased by 20%, which solves the common problems of soft brake foot feeling and delayed response of traditional calipers.
optimize the design of piston return spring and sealing groove, eliminate brake pad drag wear, and reduce unnecessary power loss and abnormal fuel consumption.
In view of the sharp whistle that is easy to produce when braking the rear wheel, the braking process is quiet and free of interference by optimizing the pad fixing structure and shock-absorbing reed.
solve the pressure leakage caused by thermal deformation of low-end products in long downhill sections, and ensure consistent braking force under high temperature and high pressure.
provide them with standard parts inventory with high adaptation rate and low after-sales risk, and assist wholesalers to establish high-quality brake system product line.
for the pursuit of brake line sexy and appearance texture of the players, to provide a variety of color options and performance is better than the original rear brake upgrade program.
to meet the strict procurement standards of high-end motorcycle or high-power electric two-wheeler manufacturers for braking safety, lightweight and batch stability.
provide technicians with replacement parts with convenient installation and accurate tolerance to solve the maintenance requirements of aging and clamping of calipers and reduced braking performance after old models.
A: Yes, all factory calipers are pre-installed with a set of high-quality semi-metal brake pads, which can be installed and used out of the box.
A: The piston is made of 45# steel or high hardness aluminum alloy with hard chromium plating, which has strong oxidation resistance and will not rust under normal use.
A: As long as the distance between the installation holes of the rear caliper of your original car is 84mm, you can directly fix and replace it with bolts without additional transfer codes.
A: Using high-standard EPDM sealing ring, it is recommended to check every 24 months or 30,000 kilometers. If there is no leakage, there is no need to replace it.
A: It is compatible with the mainstream DOT 3, DOT 4 and DOT 5.1 brake fluids on the market, but it is strictly prohibited to mix brake fluids with different labels.
A: This product is mainly designed for the displacement range of 125cc to 600cc. It is recommended to confirm the thickness and installation hole distance of the rear brake disc of the original car before purchasing.
