How to change SSR125 pit bike brake fluid?
Since your pit bike brake work on brake fluid, you need to refill the fluid once it’s low. The way you need to change it is a bit tricky. You should be careful about handling the brake fluid because it can harm the painting of your bike and can do the same to your skin. Follow the steps to replace the brake fluid.
- Locate the Master Cylinder Reservoir at your pit bike. It’s more often at the right handle.
- Open the cylinder cover. Replaceing the fluid is called bleeding the brake. So be careful about that.
- Replacing the fluid will let some air pass in the brake cable. So you have to remove the air manually.
- Take out the old fluid with some sucker maybe a syringe. Clean the cylinder with some cotton
- Pour new fluid in the cylinder and fill 90%.
- Now we need to take out all air from the brake cable.
- So, you should pump the brake lever to make pressure. Hold the lever after some pressure.
- Then connect a pipe to the bleeding cable connector. Put down the other end of the pipe in a container for drainage. Loosen the bleeding bolt with bleeding tool.
- Let some fluid pass through the pipe. This way the air in the pipe will come out with the fluid. Passing out of the fluid will loosen the pressure of the lever.
- Before the cylinder becomes empty and air goes in, tighten the bleeding bolt.
- Then refill the cylinder with fluid and repeat the same process to make sure there is no air or air bubble in the brake cable.
- Once you are sure there is no air, fill up the cylinder again and close the cap properly.
Proper replacement of the brake fluid will make you feel the brake lever firm to pump. You should then clean up your bike. Because the fluid is a toxing chemical that can burn any soft surface.
