Vapor lock prevention and remedying

Use only Shimano genuine mineral oil or a

proper equivalent. If any other type of oil

is used, it may not only cause vapor lock,

but may also damage the brake system.

Be careful not to let any water or air

bubbles get into the brake system,

otherwise vapor lock may occur. Be

particularly careful when removing the

cover of the reservoir tank.

If vapor lock occurs, stop riding the

bicycle immediately.

The cause of vapor lock is usually water

mixed in with the oil, so replace the oil with

Shimano genuine mineral oil.

Disc Brake

Disc brakes have a burn-in period during which the rotors are rubbed

by the pads, and the braking force will gradually increase as the burn-in

period progresses. Make sure that you are aware of any such increases

in braking force when using the brakes during the burn-in period. The

same thing will happen when the brake pads or rotor are replaced.

Be sure to use only oil from a freshly-

opened container. This is because the oil

may absorb moisture from the air after the

container is opened.

Vapor lock may occur if the brakes are

applied continuously. To relieve

this condition,
