Another Volvo fellow got air out of ABS by braking hard a few times on a snowy road. In a controlled manner, of course. Then he bled the brakes normally, air bubbled out.jonesg wrote: 05 Aug 2022, 12:47 I had a Ford truck with same problem.
There was a big air pocket trapped in the master cyl.
I pulled it off and bled it on the table.
People have success using a turkey batter and small tube.
A big truck mechanic told me he just sucked it out with a straw and spit it out.
Don't think straw or anything can let the air out if it's trapped behind closed valves.
