It may be a good idea to follow the fluid flow. First check that you can get fluid to flow from the master to the line (loosen the fitting at the master cyl while someone steps on the brake) then lock it down and move to the other end and do the same thing at the valve. then, on the outlet side of the valve. If the valve is stuck, replace it.

I need to replace the neutral safety switch on a 1989 Jeep Comanche 5 speed manual transmission

I think you are referring to the clutch pedal safety switch. If so it is located behind the clutch pedal under the dash.

How do you set the valves on a 1989 Jeep Comanche straight line 6?

You have hydraulic lifters that do not need to be set. Make sure the pushrods are centered in the lifters and tighten the rocker bridges down alternating sides to keep them even. Pretty sure torque on those is 15 foot lbs. If installing new parts always put a swipe of white lube or pre-assembly lube on all pivot points to keep them from galling before the engine oil can reach them.

1988 jeep comanche shakes when braking 2wd

A faulty stabilizer could be causing a shake like that, especially if you run bigger tires or a lift. Also check your alignment and make sure other steering components are tight and there is no steering play.

check control arms and front axles. worst case scenario the brake calipers may be flexing.

Hope helps (remember to rate and comment this).
