1. The two hydraulic circuits are as follows:
(A) Front right caliper and rear left cylinder.
(b) Front left caliper and rear right cylinder.
2. If the master cylinder or pressure control valve has been disconnected and then reconnected, then the entire system (both circuits) needs to be blown out.
3. If you have disturbed the components of only one circuit, then you only need to blow through this circuit.
4. Due to the design of the hydraulic system and the arrangement of the pipes, satisfactory blowing can only be achieved by using a blowing kit. These kits are available at auto supply stores and usually work using compressed air from a spare tire.
5. By connecting some container of compressed air to the master cylinder fluid reservoir, you can perform a purge by simply opening each nipple in turn and allowing the fluid to flow out, just like a faucet, until there is no more air in it.
6. When using this method, a large supply of hydraulic fluid acts as a guarantee that no air will enter the master cylinder during this operation.
7. This method is especially effective when it is necessary to blow "complex" system and when the entire system is purged during the next current fluid change.
8. Bleed the front and then the rear brake of one hydraulic circuit, then bleed the front and rear brake of the other circuit.
9. Pour out any fluid that was in the system.
10. Fresh liquid used for purging or refilling should always be stored in an airtight container and should not be shaken less than 24 hours before use.
11. During the bleeding operation, it is allowed to slowly press the brake pedal two or three times to facilitate the release of air from the system.
12. When finished, check the fluid level in the master cylinder again, add fluid if necessary, and install the cap. Check the condition of the brake pedal - the pedal should be stable and it should not feel like "sponge", which will mean that there is still air in the system.
