Purpose and function in the braking system
The presented rear brake caliper with lever mechanism and pump is the element of the braking system responsible for generating and transmitting working pressure to the brake pads on the rear axle of the Qingqi QM 125 motorcycle. Integrating the caliper with the actuator and lever translates into consistent operation of the entire component and facilitates installation in place of the factory element.
The location on the vehicle's rear axle ensures proper distribution of braking force between the front and rear of the motorcycle, which is crucial for stability during emergency braking and in everyday city and touring riding.
Set construction: clamp, lever, pump
The kit includes a brake caliper with a lever mechanism and a master cylinder, creating a functional rear brake module. This configuration:
- simplifies the replacement process – you dismantle the old module and install a new one in its place,
- reduces the risk of incorrect selection of individual elements,
- ensures consistent operation of the pistons, levers and brake master cylinder.
The modular solution is particularly beneficial when servicing motorcycles used daily, where a quick return to full functionality of the braking system is crucial.
Technical condition and advantages of a used item
The offered component is in used condition, which means that it shows signs of normal use, but retains the functionality required for further safe use after proper installation and possible operational service (bleeding of air, inspection of hoses, selection of appropriate brake pads).
Key advantages of this particular copy:
- low mileage of the donor – limited wear of working surfaces and moving parts,
- original mounting geometry – easier installation in place of the factory rear caliper in the Qingqi QM 125,
- the completeness of the module is maintained – the clamp, lever and pump work together as one system.
For the user, this means the ability to restore the rear brake performance without having to invest in a new, much more expensive set.
Selection, compatibility and security aspects
Before purchasing, it is worth comparing the design of the module offered with the element currently installed on the motorcycle, paying attention to:
- type and location of mounting points to the swingarm or frame,
- brake line connection type,
- the geometry of the lever and the way it interacts with the brake pedal.
A properly selected rear brake caliper with master cylinder has a direct impact on riding safety. After installation, it's recommended to thoroughly bleed the system, check for leaks, and perform a brake test in safe conditions before returning the motorcycle to normal operation.
