The process of removing brake calipers requires meticulous care and caution. The specific steps are outlined below:
First, lift the vehicle's rear wheel and ensure it is securely supported to guarantee operational safety. Next, disconnect the motor wiring and remove the bolts securing the rear brake assembly. During this process, gently pull out the brake cable and remove the bolts located on both sides of the rear axle.
Subsequently, detach the drive chain and remove the mounting bracket to facilitate the smooth removal of the rear wheel. Then, carefully extract the rear brake assembly and use a specialized tool to detach the brake disc from inside the assembly. Once the removal is complete, securely install the new brake disc in its proper position.
Following that, install the adjustment shims, ensuring that all components are assembled in the correct sequence. Upon completion of the installation, perform a thorough inspection to verify that all parts have been correctly installed and are firmly secured.
It is crucial to pay special attention to the installation and adjustment of the rear brake assembly. Improper procedures can lead to malfunctions such as brake misalignment, brake failure, motor seizure, or the occurrence of abnormal noises while riding. In severe cases, such errors could even result in the deformation and irreparable damage of the internal brake drum, severed motor wiring, or uncontrolled motor burnout.
Therefore, if you are unfamiliar with this procedure or lack the necessary experience, it is strongly recommended that you seek assistance from a professional electric vehicle repair shop to ensure the safety and effectiveness of the repair process.
