So how to replace it, let's talk about the replacement steps of the brake cylinder cup, and then we will give a schematic diagram of the replacement of the brake cup, which will make it more convenient for us to operate.
Replacement steps of brake wheel cylinder cup:
1. First release the car's handbrake, and then unscrew the screw on the back of the brake cylinder until it stops.
2. Then tighten the handbrake again, remove the sub-cylinder from the car, and make a mark on the upper and lower bodies of the sub-cylinder to avoid errors when returning to Shian.
3. Remove the two screws and nuts on the outer semicircle of the sub-cylinder, and you can see the damaged cup.
4. Finally, directly replace the new sub-cylinder cup and you are done. Of course, we have to follow the reverse steps to install the parts back.
5. After installation, we'd better put on the handbrake one more time to check if there is any air leakage.
