Filling the Reservoir with New Fluid
After you’ve got flushed the outdated brake fluid from the system, it is time to fill it again up with new fluid. Here is learn how to do it:
1. Examine the fluid stage
Earlier than you add any new fluid, test the extent within the reservoir. It ought to be between the “MIN” and “MAX” marks on the aspect of the reservoir.
2. Add fluid slowly
Add new brake fluid to the reservoir slowly, utilizing a funnel if mandatory. Do not overfill the reservoir, or the fluid will overflow whenever you pump the brakes.
3. Open the bleed screw
Find the bleed screw on the caliper of the brake that you just’re engaged on. Open the screw barely, in order that fluid can circulation out.
4. Pump the brakes
Have an assistant pump the brakes slowly when you watch the fluid stage within the reservoir. Because the fluid stage drops, add extra fluid to the reservoir.
5. Shut the bleed screw
As soon as the fluid stage is between the “MIN” and “MAX” marks, shut the bleed screw. Tighten it snugly, however do not overtighten it.

|---|
|
Entrance proper caliper: High of the caliper |
|
Entrance left caliper: Backside of the caliper |
|
Rear proper caliper: Rear of the caliper |
|
Rear left caliper: Entrance of the caliper |
6. Repeat for different brakes
Repeat steps 3-5 for the opposite brakes in your car. As soon as you’ve got flushed the entire brakes, test the fluid stage within the reservoir one final time and ensure it is between the “MIN” and “MAX” marks.
Bleeding Brake Traces to Get rid of Air Bubbles
