Been there, done it! Easy fix!
Here is what is happening, you have high resistance in the large wire
going to the + terminal of the battery from the relay block, it isn't
noticeable except during the loads you put on it, this resistance
indirectly removes the battery from the system, which in turn, acts as a
shock absorber as you add or remove a load, when you step on the brakes,
you have applied a load, when you release, you create a spike. To
correct this problem, get a good Weller Solder gun, one that goes
200/260 watts (2 stage) minimum, then get some good 60/40 rosin core
solder and some rosin core flux, clean the area as best as you can, soak
the cable and eyelet with flux, get it real warm, enough to melt the
solder, then just let it melt and absorb in the cable around the eyelet.
Have it done if your not familiar with soldering, good heat is critical,
or you'll end up with a "cold solder joint" and the same problem.
Believe it or not, we have seen this quite a bit, on 94-95 4Runners
only.
