I own a 1979 CJ-5 with a 401 dropped in it. It still has the stock exhaust
manifolds. I don't like aftermarket headers: so they will stay ! The problem
that I have is after 2-3 hours of 4 wheeling the brake lines heat-up and I
lose my brakes. I had this happen while I was near a stream. so to prove the
point to myself I cooled the brake lines with water and after that they
worked fine again. The flange of the manifold is but a scant 11/2 inches
from the bake lines on the frame. will consider all possible solutions.

 

Have your brake lines power-flushed to get all of the old and most likely
contaminated brake fluid out. It sounds like you have moisture in your
brake fluid.

Run DOT 5, it was designed for high temps, and re-route the lines.

Sounds like you're blaming the exhaust as if it passes too close to
one of the lines, if so, relocate them, or place a piece of sheet metal
in between to deflect the heat.
