<VV> Knocking Out Adjuster Knockouts in Brake Drums

[J R Read_HML]

Either method works.  The rubber plugs work.  You may want the knockouts 
removed for some time in the future when you want to back off the adjusters 
for drum removal purposes.

If you don't have a wheel cylinder that is stuck on one end, then the likely 
source of your pull is either contamination of the brake lining or a rubber 
hose that is disintegrating on the inside.

I have no experience with the Kevlar.
