[T3] Brake Pedal Pushrod?

[Dave Hall]

I've sent the diagram to Jim.

It starts for Beetles from chassis 119 480 132 (Jan 1969?), but I'm not sure
if that's when dual circuit came in for them, but does not specify a chassis
number for the Type 3, so I presume it applies to all of them. 

I guess you would want the brake and clutch pedal in the same plane, so I'm
not sure the brake pedal can be set up closer to the bulkhead, and if you do
that with the clutch pedal, you lose some of the throw, which might not give
full movement on the clutch mechanism.  I may be forgetting the situation,
not having worked on that area for years, but doesn't the stop plate work on
the clutch pedal, rather than the brake?  

The Type 3 parts book definitely specifies the longer pushrod from the dual
circuit change-over.  It also specifies the earlier boot for the single
circuit push-rod.

I wouldn't use the shorter brake push-rod on a dual circuit system - I think
you wouldn't get the second system working if the other failed.

If you check out the replacement pan parts, you'll find lots of notes to
replace various parts for various different earlier VINs, but none of those
changes occur at the 3x7 123 nnn region, and none mention replacing the
pushrod, so I don't think they moved the pedal cluster. 
(Unless they did, and forgot about it when writing it up in the parts list.
That would be unusual, but not unheard of.)

Once you installed the late pushrod, did you have to readjust the pedal stop
to get the free play right? If so, maybe the whole thing comes down to a
change in the relaxed pedal position, to get more stroke for the tandem MC.
If that's what happened, I'd expect the setting gauge drawing to call out
that this was just for cars after
3x7 123 nnn. I hope Dave will check the drawing for this.  

If that's what happened, that would move the relaxed position of the pedals
back toward the driver 2-3", which seems like a LOT.

Maybe someone else can tell us whether the pedals on earlier cars are much
closer to the floor.
