[QUOTE="Donal, post: 1353429, member: 20675"] [I]"and open the bleeder” hasn’t worked I have solved the problem by pushing the air “up”, by pushing in a caliper piston or slave cylinder pushrod-AFTER flushing clean fluid through the entire system."[/I] My only comment here is be very careful doing this with an FJR ABS system! There are very tiny ports in the ABS block which will become extremely difficult to unblock if contaminated. It is not possible to back-flush them because there are check valves in parallel which will allow fluid to flow freely around the blockage. [/QUOTE]
