Hi and welcome.
Good to see you've got your priorities right, brakes first!

You'll may be aware there's a sub-forum especially for Suburbans andPanel trucks and also a forum for the heavier load rated trucks.

Between them i'm sure you'll get all the help and info you'll need.
BTW Pictures would be nice....
Good luck.
Jock.
