Have both 99 models of TJ & XJ, both 4.0 litre - need new brake booster vacuum check valves - the part numbers appear different on the parts manuals I can find, yet they appear identical when compared side by side and are fit interchangeable - but are the internals the same specifications, gaps, pressure allowed/created, etc.
In reality can I / should I use one in the other, etc.?
Any guidance from a real expert or experience with braking systems appreciated.
