I had a similar issue once I had rotated the brake block to be in line
with the swing arm and found that on occasion the block would contact
the inside of the tunnel on retraction if there was enough force on
retraction to move the arm past the up position due to the momentum of
the arm.
I tried using aluminium angle but soon discovered that there was enough
overthrow in the arm beyond the normal up location to bend the angle out
of shape within a couple of retractions. I am now using a fairly strong
piece of angle with triangular insets welded in place to support the
angle. The contact surface is covered with a rubber pad to buffer the
impact.
If you do this you will need some way of dissipating the force along the
tunnel wall. Driving a couple of bolts through is not going to do the
job so you'll need to look at a support plate either inset or bonded and
glassed onto the tunnel wall.
