For operation safety, never fail to perform periodic maintenance or make periodic replacement of the consumable parts listed in the following.

These parts may deteriorate in time and are susceptible to wear. It is difficult to estimate the degree of wear at time of periodic maintenance; therefore, even if no apparent wear is found, always replace with new parts within the prescribed period of replacement (or earlier if trouble is found).

Note that periodic replacement has nothing to do with guarantee service.

Replace Master cylinder and wheel cylinder cups, dust seals

Replace Rubber parts of brake booster;

Warning: Always make sure to prepare the container for receiving draining water and bleeding air. Wipe up spilled fuel if any, because it may be in danger to cause fire if fuel sticks here and there.
