Sheldon, you have me really interested in this now<G>!
I pulled out a Studebaker Service Operation Time Guide, the oldest one
I had for the mid-to-late fifties, and early sixties. This is what I
came up with, from the time guide:
R&R brake linings, adjust front wheel bearings, bleed brakes = 2.9
Wheel cylinder rebuild including honing 0.7 each = 2.8 hours
Install front brake hoses (subtracting the bleeding) = 0.2 hours
Rear brake line (didn't have this specifically, but used other tasks to
estimate) = 1 hour
Wheel studs (not in guide, didn't know how many, guessed) = 0.5 hour
Note that these times did not include cutting the drums on a brake drum
lathe, which would have been an extra 2.2 hours. Also, no time was
added for messing around with the hill holder.
This total (without cutting the brake drums or messing with the hill
holder) is 7.4 hours. Would there be extra time (based on problems with
stuck fasteners, rust, unfamiliar tasks such as rear drum removal, etc)
working on a 60 year old car versus a 1 or 3 or 6 year old car?
Probably, but I don't know how to factor this in.
