Air Bleeding for Brakes procedure
So I am reviewing the Service Manuals, specifically for air bleeding the brakes and it states:
Air bleeding operations are generally performed in the following sequence. 1) Bleed air from primary side of circuit between hydraulic unit and master cylinder using FL and RR primary air bleeders on top of hydraulic unit. 2) Bleed air from secondary side of circuit pressure reducing circuit, using FR and RL secondary air bleeders on top of hydraulic unit 3) bleed air from line between hydraulic unit and wheel cylinder using FR wheel cylinder air bleeder 4) using step 3) above, air is bled from RL wheel cylinder 5) using step 3) above, air is bled from FL wheel cylinder 6) using step 3) above, air is bled from RR wheel cylinder So the sequence for bleeding is FR (Passenger side front), RL (Driver's side rear), FL (driver's side front), and RR (passenger's side rear)...correct? Is the air bleeding sequence for the hydraulic unit in the engine bay the same as bleeding from the calipers? (Meaning, you stick a clear tube to the air bleeder and while the air bleeder is open you press down on the brake pedal). I am assuming there is a way to loosen the air bleeders on the hydraulic unit in the engine bay? |

If you're just refilling/bleeding you'll need someone to press/release brake pad on your command. As you open and close bleeder screw. If you've replaced brakeline, etc. even w/ pump and bleed you may just have to let gravity do it's job, if you can't get it firm. Just barely crack a bleed screw, let it bleed on it's own for awhile. Just remember to keep the brake res. topped off.

Right, but is bleeding procedure the same on the hydraulic unit itself as it is on each of the calipers?
