Lots of close tries on the brake connection issue, but no complete
answers that I've seen yet. None of the brake manufacturers, neither
factory nor OEM suppliers, were consistent about which end of the master
goes to which end of the car. If you have a proper master cylinder for a
disk/drum setup, the reservoir will be divided into large and small
volumes. The front disks are fed from the end with the larger reservoir,
and the rear drums from the end with the smaller. The larger reservoir
is a safety feature allowing the pads to wear, which increases the
volume of fluid required, without running out of fluid. If your master
does not have different size reservoirs, it's a drum/drum master. You
can use it, provided the diameter is correct, but be sure there is no
residual valve under the tube seat to which you connect the front
brakes, and be *especially* careful to check the fluid level frequently.
On the residual valves, they can go anywhere between the master cylinder
and the point where the lines split right and left--10lb valve for the
rear and 2lb for the front, as posted by another. The purpose of the
rear residual valve is to keep a small amount of pressure on the wheel
cylinder seals to prevent the entry of air. The purpose of the front
valve is to prevent siphoning of fluid from the calipers to the
(low-mounted) master cylinder when the front is high. They can do those
jobs no matter where they are located.
The adjustable proportioning valve can go anywhere in the rear brake
line between the master and the point where the line splits to the rear
wheels. OEM type combination valves as used on later vehicles must of
course be located close to the master because both lines are routed
through them.
