USEFUL TIP: Immediately after disconnecting the hose from the reservoir, plug its opening without lowering the hose down. Some working fluid will remain in the hose, so after installing the reservoir and connecting the hose to it, there is no need to bleed air from the clutch release hydraulic drive.

6. Loosen the nuts securing the two pipes to the brake force regulators, holding the regulators from turning with a second key..
