Air Bleeding

1999 Mazda 626 ES, 2.5 D, StandardSECTION Air Bleeding
WARNING: This page is about a different car, the 2005 Mazda 6. However, it is still accessible from the selected car via links, so may be relevant.
CAUTION:
  • Maintain the fluid level in the reservoir tank proper while bleeding the air.

Specified fluid 

SAE J1703, FMVSS 116 DOT3 

NOTE:
  • The brakes should be bled whenever a brake line is disconnected. If a hydraulic line is disconnected at the master cylinder, start at the slave cylinder farthest from the brake master cylinder, and move to the next farthest slave cylinder until all four cylinders have been bled. If the disconnection point is anywhere except the master cylinder, start at the point closest to the disconnection, and move to the next closest slave cylinder until all four cylinders have been bled.
  1. Remove the bleeder cap and attach a vinyl tube to the bleeder screw.
  2. Place the other end of the vinyl tube in a clear, fluid-filled container.
  3. One person should depress the brake pedal a few times, and then hold it in the depressed position.
  4. A second person should loosen the bleeder screw, drain out the fluid and close the screw using the SST.
