<VV> Brakes

[Frank DuVal]

If it is always the left rear locking up, you can check shoes by 
switching them from the left to the right, etc.

My bet is always on the brake hardware and flexable hoses. Take the 
springs off and see if one side was harder to remove than the other. 
Drop the springs on a concrete floor and see if any sound different. 
Overheating and/or stretching cause changes in the spring rate that can 
be heard. So if similar spring sound different, change them.

I NEVER turn drums unless there is actual damage to them. This is a pet 
peeve of mine. Why do mechanics turn drums as part of a typical drum 
brake job when there is no damage? Any unnecesary metal removal make the 
drum that much closer to the scrap pile. Now Corvair drums are plentiful 
used, so not much problem here, but try to find aluminum finned front 
drums for a 60's Buick....

OK, off the soap box!

I would have bled the fronts when bleeding the rear. This flushes the 
whole system.

Is the backing plate lubed where the shoes ride?

Make sure both sides are adjusted the same.

Again, hoses can go bad internally with the outside looking great.
