Re: [Amc-list] Power brakes to manual brakes on 81 Concord - couple questions

[Wrambler242@xxxxxxxxxxx]

I can't remember the mount setup for manual brakes.
IIRC it uses two studs in the two holes that align across the hole side to side that the pushrod runs through.
Place bolts in the other two holes and tighten them as it holds the steering colomn and brake pedal support braket to the firewall, You don't want that coming lose!
To get a rod.
Buy a rebuild master is easiest.
It should be less than $20 and the rod is usually loose in the box.
Line side should not matter, just as long as they fit and you get them bolted to the same front to front, rear to rear configuration.
  On the pedal arm inside, you will see two holes.
Whatever hole it uses now with power brakes, well, it's wrong for manual, move to the other hole. One hole is for power, one for manual. I forget which is which. It is slightly possible it is allready in the manual hole. Sometimes people get it wrong when they work on them. Usually only happens with manual brake cars as the booster does not get swapped out often.
   Once you have it all working and your happy, sell the power brake stuff.
someone will want it!
