The air in the hydraulic circuit acts as a pad, absorbing a large amount of the pressure exerted by the brake pump and reducing the efficiency of the braking. The air present is felt at the brake pedal, making it seem "spongy" and reducing the braking capacity.

Use solely the specified brake-clutch fluid.

The brake-clutch fluid is extremely harmful for the paintwork; if it accidentally comes into contact with a painted surface, remove it immediately and clean the area thoroughly.
