If you happen to crack your rear rotor housing vent by
tapping it out for a 1/4 pipe  here is how to fix it.
This is a Mazdatrix idea. I used a dremel tool to
get down to the bare metal around the crack. I then
put JB Weld on the 1/4 pipe threads inside the hole. I also
coated the outside of a 1/4 pipe to 1/8th pipe
adaptor and screwed it into the hole.
don't try to unscrew it after the JB Weld sets up.

Best to use a 1/8th pipe tap here from the get go as there
is not really enough meat around the hole  for a 1/4 pipe tap.
