[TR] TR3 10" rear brakes

[Andrew Uprichard]

I have always dealt with 9" rear brakes, so help me out here:

 

The smaller brakes have a pin which comes through the shoes and is held in
place with a clip.  The 10" set-up appears to have a pin which screws in
from the outside and is secured with a nut.  Does this pin abut against the
shoe or should it go through ?

 

And while I am at it, what is the purpose of the hole in the drum?  Air
flow?  Cooling?  Access?
