Thanks for sharing this
Richard!,
Your father is absolutely right, you need
to adjust the cam adjusters (4 in the front and 2 in the rear)
frequently to get a good working braking system.
I have adjusted the way you father
described it, and I must say I have a firm pedal that travel only
halfway to the floor!
Maybe the other 60 owners, Paul, Tom,
Kenyon and Charles can jump in on this and tell us how much pedal travel
they have?
And since we are talking about 1960 Imps
here, what is the correct reading for the temperature of our
cars?
Since the weather is almost freezing cold
here, my car doesn't reach normal operating temperature. It just passed
the Cold mark on the dial and thats about it. Since it is a Californian
car I thought the former owner might have installed another termostat
that opens earlier, so I checked it and I was right!
The previous owner installed a 160 degrees
thermostat!, I guess to prevent the car from overheating in hot
Californian summers.
I now have installed a 180 degrees
thermostat (OEM standard temperature) and the needle on the gauge goes
higher then ever before! It now stays exactly in the middle of the
dial.
Is this correct?
I have never seen the needle climbed that
high before, so I am a little worried allthough common sense tells me
that the middle of the dial sounds quite good...
Just curious to know the readings on other
1960 owners temperature gauges!
Thanks,
Robert

Subject: IML: 1960 Imperial brake
bleeding
Hi Folks,
After spending countless hours working on the brakes on my '60
Crown they are finally working properly. I think we bled them
entirely three times before getting everything repaired
properly. The shop that "restored" my chasis did not double
flare the brake lines correctly and had overtightened the flares at
the bronze blocks creating distortion and leaks. We ended up
replacing all of the lines again and the blocks as well, at the front
frame and on top of the axle. The IML web site was helpful but
did not really address the issue of pedal going to the floor.
See below. Another tip, we elevated our brake bleeding bottle on
a small step ladder, that really helped keeep the air from returning
to the cylinders during the bleeding process. After all of this
my father had this to say:
For Imperial Club under "Repair" , "Brakes", "Brake
Bleeding".
The 1960 Imperial and like years brake systems can be
perfectly bled and the pedal still go to the floor if the brake
shoes are not adjusted to require minimal movement to
brake the drum. The bottom line is that with six cylinders
to provide fluid too, the master cylinder will be at the end of its
stroke (to the floor) before the wheel cylinders have enough fluid
(pressure) to push the shoes tight against the drums. Chrysler knew this,
as in the Maintenance Manual under "Pedal goes to Floor" you (a) check
fluid in master cylinder and (b) adjust for worn
linings. The obvious implication is that it does not
take much slack at the brake shoes to allow the pedal to go to the
floor. With the shoes properly adjusted tight against the drum
and just loosened enough to allow the wheel to turn freely you still
will not have a firm pedal until you almost reach the floor.
That's just the way it is. If you want to see this then tighten
all the shoes against the drums and then see how much pedal
you have. You cannot see this by pumping the pedal as the strong
shoe return springs will push the fluid back out of the wheel
cylinders faster than you can stroke the master cylinder. Adjust
the shoes properly and frequently and you can get good
braking.
