Bleeding air from the hydraulic circuit of the clutch release drive (Honda Civic 6)

The hydraulic drive of the system release must be bled every time after its components are removed, and also when the fluid level in the reservoir drops so much that air gets into the master cylinder. The principle of bleeding is the same as that used when removing air from the brake tract.

1. Fill the master cylinder with fresh DOT 3 brake fluid.

Attention! Do not reuse liquid that has been pumped out of the system, or liquid that has been stored in a loosely closed container for a long time.

2. Jack up the vehicle and place it on supports, ensuring normal access to the slave cylinder on the clutch dome.



3. Remove the dust cap and fit the end of a suitable sized plastic hose onto the cylinder bleeder valve (see accompanying illustration). Place the other end of the hose in a container with transparent walls partially filled with brake fluid. Make sure that the cut end of the hose is completely immersed in the fluid.

4. Ask an assistant to depress the clutch pedal and fix it in the lower position. Open the bleeder valve and release the fluid from the cylinder into the drain container. When the flow of fluid mixed with air bubbles stops, tighten the valve tightly again and allow the assistant to release the pedal.



5. Continue bleeding in the same manner until the fluid coming out of the cylinder is completely free of air bubbles. Constantly monitor the fluid level in the master cylinder reservoir, not allowing it to drop too low, which could result in air getting into the tract and nullifying all efforts made.

6. Once bleeding is complete, disconnect the hose and replace the dust cap. Lower the vehicle to the ground and check the clutch for proper operation.
