(a) Front right side caliper and rear left side cylinder.
(b) Front left side caliper and rear right side cylinder.
2. If the master cylinder or pressure regulating valve has been disconnected and then reconnected, then the entire system (both contours) needs to be blown out.
3. If you have disturbed the components of only one circuit, then you only need to blow out this circuit.
4. Due to the design of the hydraulic system and the arrangement of the tubes, satisfactory blowing can only be accomplished using a blowing kit. These kits are available at auto supply stores and typically operate using compressed air from a spare tire.
5. By connecting a compressed air container to the master cylinder fluid reservoir, you can blow out the fluid by simply opening each nipple in turn and allowing the fluid to flow out, just like a faucet, until there is no air left in it.
6. When using this method, a large supply of hydraulic fluid acts as a guarantee that air does not enter the master cylinder during this operation.
7. This method is especially effective when it is necessary to blow out "complex" systems and when the entire system is blown out during the next current fluid change.
8. Bleed the front and then the rear brake of one hydraulic circuit, then blow the front and rear brake of the other circuit.
9. Pour out the liquid that was in the system.
10. Fresh liquid used for purging or topping up should always be kept in an airtight container and should not be shaken less than 24 hours before use.
11. During the bleeding operation, it is permissible 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 firm and not feel like a "sponge", which would mean there is still air in the system.
