Questions: Is there a retainer to hold the plunger in place? Mine pulls away from the master cylinder and will not stay engaged with the piston.
Question By: Eddie on Mar 9 2019 11:03 PM
Make to double check your free pedal travel. That sounds like the issue.

Questions: My old push rod does not seem to be long enough and it is not adjustable (Rusted beyond moving). First, how much will this push rod adjust, and how do I know when it is adjusted correctly? Thanks
Question By: Neil Netoskie on Jun 26 2017 3:52 PM
You want 1" of free pedal travel. That is how you know. The push rod is theaded and adjustable.

Questions: I have been involved in a project for too long now. jeep basket case one problem after another. Trying to do the brakes not only does the master cylinder not fit but now I find the pushrod is way short. - that is what I assume. the brake pedal sits way down by the engine block before it does anything which leads me to believe that there is a difference in brake pushrod lengths especially considering two listings in descriptions for pushrods. Am I correct?
Question By: Chris on Apr 3 2015 12:00 AM
Yes, there is a small difference in push rods from vehicle to vehicle model. That is why we list different ones. CJ-2A did you two different style master cylinders (805223 or A556) and two different push rods (647606 or A183) from what you've written above sounds like that is what you have.
