Chris and Alana Posted November 4, 2007 Share Posted November 4, 2007 A little late but when I changed my brakes and lines I had the engine running all the time during bleeding. I think it may have been Mr Wilson that suggested it to help bleed through the ABS system aswell (sorry if im wrong here chris ) Quote Link to comment Share on other sites More sharing options...
Suprash Posted November 5, 2007 Share Posted November 5, 2007 If your engine isnt running then does your brake servo not cease up with pressure.....? Quote Link to comment Share on other sites More sharing options...

Tricky-Ricky Posted November 5, 2007 Share Posted November 5, 2007 If you bleed with the engine running you will have residual pressure on the master cylinder and so will have fluid being forced out as soon as you crack a nipple. Quote Link to comment Share on other sites More sharing options...

So thats a no no to leaving the engine running ? Quote Link to comment Share on other sites More sharing options...
