Master Cylinder is Not Pumping Fluid

Updated 05/12/2017 | Published 05/11/2017

Question:

Do I need to prime it to pump fluid again.....or how can I check to make sure the master cylinder is pumping fluid. When I pump the master cylinder I dont see any fluid coming out the line disconnected from master cylinder. Thanks

If your actuator, like part # T43397007K, is new and you are testing the master cylinder without it being in the fully assembled actuator then that would be your problem.

If your actuator is not new then you will want to look for any clogs in the brake line. There should be fluid moving through the line even with it being disconnected from the brakes. Try cleaning the brake line and if that doesn't help let me know and I can help you to troubleshoot further.
