Advice on a couple of problems with the Arrow

Pinging the collective wisdom of the r.a.o folks on a couple of
maintenance issues:

1) Our engine monitor (JPI EDM-700) sometimes indicates sporadic EGT
values for #1 cylinder. It behaves like a sensor or connection issue as
the engine runs fine and the fuel burn is within expected values. #1
CHT value dances up and down fairly rapidly +/- 25 degrees or so of the
value as compared to the other cylinders. The value changes fairly
rapidly (much more so than with the other cylinders). The problem has
come and gone consistent with some sort of wiring issue. Anyone seen a
similar problem? Engine is IO-360.

2) Right brake pedal travel is noticeably more than the left. Stopping
power of both brakes is fine and the fluid level is only slightly down
from the full line. Applying the parking brake while rolling causes the
plane to slightly turn left, consistent with the left brake applying
ahead of the right. No hydraulic leaks anywhere that I can see. Could
it be air in the system that needs to be bled? I'm familiar with this
in cars and have done my share of bleeding brakes and hydraulic
clutches. The airplane domain is new though.

Thanks!
