natas Posted July 17, 2014 Share Posted July 17, 2014 The other day I topped up my brake fluid with PAS fluid. I read that the entire system had to be changed so I did just that. Brake master cylinder, all rubber lines and all 4 new calipers. Its a 1998 300tdi 90. Now that I have it all installed I have bled the system at least 5 times but cannot get the brakes working properly, it still feels like air in the line. When I press the brakes it either works fine or the pedal gets soft and almost goes to the floor with very little brakes, or the pedal feels really hard and there is very little brakes. Am I missing something? Thanks. Quote Link to comment Share on other sites More sharing options...
Disco-Ron Posted July 17, 2014 Share Posted July 17, 2014 Are all the bleed nipples at the top of the calipers??..... I have a bleeding tool that sucks the fluid through, its brilliant, never failed yet, but I would also advise a few pedal pumps whilst doing it....

natas Posted July 18, 2014 Author Share Posted July 18, 2014 Got it sorted. Mechanic was bleeding without a hose and jar of fluid so it was sucking air back up 20 minutes with the proper method and now she is fine again. Thanks. Quote Link to comment Share on other sites More sharing options...
Retroanaconda Posted July 18, 2014 Share Posted July 18, 2014 Not the most experienced mechanic then!? Also, why put PAS fluid in the brakes? Quote Link to comment Share on other sites More sharing options...
