Brake Fluid - Hudson Terraplane 1950 Owner's Manual

HUDSON OWNER MANUAL
The brakes are of the Bendix Duo-Servo single anchor type, employing wider shoes
and larger wheel cylinders at the front than at the rear for maximum brake efficiency
and smooth stopping. The shoes are expanded at the top or anchor end by the wheel
cylinders, which are actuated by hydraulic pressure exerted by the master cylinder
through foot pressure applied to the brake pedal.
If at any time, the hydraulic system should fail due to an accident or some other
cause, continued pressure on the foot pedal automatically applies the mechanical
reserve system on the rear wheels.
Numerous rubber parts are used in the hydraulic system which makes necessary the
use of brake fluids that are entirely free of mineral oil and other ingredients which are
detrimental to the rubber and may cause swelling and early deterioration. Hudson
Hydraulic Brake Fluid meets these requirements.
The master cylinder is self-compensating
and should be kept at least half full at all
times. Always wipe off the master cylinder
at the filler plug before removing plug to
check the fluid level.
The hydraulic system must be bled if air
enters the system. A spongy feeling pedal
is usually an indication that bleeding is
necessary.
Have your Authorized Hudson Dealer
inspect your brakes and check the fluid level periodically,
to insure proper operation. This should include a check of the mechanical follow-up
linkage.
To insure proper functioning of the mechanical reserve brake, it is very important
that the clevis at the front end of the pull rod attached to the brake pedal be adjusted
to maintain a clearance of 1-1/4" between the rear end of the slot and the clevis pin at
all times.
Brake adjustments should be performed by your Authorized Hudson Dealer.
However, if an emergency arises where the brakes must be adjusted before you can
reach an Authorized Hudson Dealer, the following adjustment procedure to compen-
sate for lining wear can be used.
1. Jack up all wheels clear of the floor.
2. Be sure hand brake is fully released.
3. Remove wheel backing plate adjusting screw hole covers.
4. At each wheel, with a screw driver or suitable tool inserted through the slot In
the brake backing plate, expand shoes against drum with adjusting screw by
moving outer end of tool toward center of backing plate until a heavy drag is
noted when wheel is turned by hand.
