Subject: 300C Front Brakes
Mark,
I'm just curious if you have replaced both front brake hoses. Its possible you have an internal breakdown in the left front hose that is not allowing the fluid to return back towards the master after an application of the brakes.
Also, how much size difference is there now between the diameter of the left front drum versus the right front drum. Center plane brakes are unusually sensitive to variations in diameter.

Subject: Re: 300C Front Brakes
Hi,
I've also a similar problem on the front brakes of my '57 Imperial: when
i start the car after a week the first braking are very hard. The car
goes immediatly to the left and the left wheel blocks if i push too hard
the pedal. After some miles the braking is different: the car goes
slightly to the ..right ! But braking continues to be too hard,
especially at slow speed and if i push too hard the pedal. The
passengers are throwed in the windshield or in the backrests ..
And yes the car is dangerous because if i must do an emergency braking i
don't know where the car will go !!
I've tried several times to adjust them , seems to be good at first
check then the problem arises again.
I suspect the lining (the front brakes are squealing when they are hot,
like disc brakes) , maybe too soft so too efficient ?
The front end is new as are the brakes parts (except backing plates)
Note that a friend of mine had problem with rear brakes (locked after
some miles with brake lights "on", smoke , etc..). After a lot of
checks, exchange, etc.. we found that it was the .. new rear brake hose
! It was new (from Kant..) !! The fluid went to the wheel cylinders but
couldn't go back ...

Subject: Re: 300C Front Brakes
Philippe,
The only way the situation can change from one side to the other is
if the first side that is locking is getting hot first. As that
side experiences "brake fade" from the overhot condition, then the
other side becomes more effective.
I do not like Kanter hose quality.
I would like to see someone go to a street rod supplier making steel
braided hoses and get a quantity made for our cars. I care more for
safety than authenticity.

In addition to what has been posted by others, brake shoes must fit the
drum. New shoes with a proper arc will have about .020" clearance at the
ends when seated in the drum (drum and brake shoe off car). If the ends hit
first, a very erratic brake action will result.
Proper tools cam grind shoes to fit the drum. Tooling to accomplish such is
far obsolete; operator health concerns, mostly. Practice of arcing shoes was
a necessary operation when drum size was above a reasonable limit. That
limit is not set at (generally) .060" above nominal and relined shoes are
factory cam ground to accomodate this number.
Something we see in high mileage drum brake cars and trucks is wear at the
support pads where the shoes rest against the backing plate (brakes noisey
and grab and don't release smoothly). These pads must be super smooth and in
a plane. Welding and grinding will restore the surfaces. Light coat of
synthetic brake grease (I still use NeverSeez) on the pads lets the shoes
move smoothly.
I live in a DRY area. Even so, the slightest bit of moisture in the air and
after an extended park period, I will have a first application brake noise
situation with, in particular, one of my cars.

Subject: 3.08 or 3.07 rear axle gears for 56 300 b
Again I am posting a request for any tips on leading me to a 3.08 or .07(some folks say) ring and pinion for a 56 300 B.
This ratio typically was factory installed only on Torqueflight/Imperials that were sold in the flatlands of America.
If no success I will probably switch entire rear axle assembly to a 57(which these gears are easily acquired for).
Any problems that I should be aware of here(except point deduction at Chrysler 300 meets which I can live with)?
Anyone know what is different between 56 and 57 pumpkin that precludes using 57 gear in a 56 rear end?
Car is currently equipped with a 3.54 which makes lifters sound like swapping holes at 70 mph. Yes I am aware that some will say that this is a happy sound but on a long drive it is getting harder for my old ears to hear Rush on the radio.
Check those old Imperial rear ends out there.
Thanks for any help

Subject: 300C Front Brakes (take 2)
Greetings 300 Club Members:
Thanks to those who replied to my brake problem. Let me try to explain what's happening. My first attempt may not have been clear.
My 300C was pulling to the left when I test drove the car before buying it December of 2002. The seller said the car recently had a new brake job and I found the receipt to confirm it. The master cylinder was rebuilt too. I was hoping that after a little driving the brakes would free up and the problem would go away. :-) No such luck.
I then tore the front brakes down. The brake shoe linings looked pretty good but the inside of the right front drum was not smooth. It was a bit wavy (at a microscopic level). The machinist at NAPA had never seen that before. He then mic'd the drums and said they could be turned. So I had them turned. The machinist was out when I picked the drums up so I do not have the drum IDs. Hopefully they are both the same.
I then bought some old brake shoes from a club member in Brookfield, WI and had them relined. No one that I called arcs brake shoes any more. I was told that arcing went out with asbestos brake shoe linings. Can you imagine the asbestos brake shoe dust when shoes were arced 15-years ago? The newly restored shoes do not fit perfect to the drum. There is clearance at both ends when centered in the drum. I'll have to live with that and "break the shoes in".
I noticed that the right front brake shoe contacts the drum at the top end of the shoe (rather than the middle) when installed. It can be seen by rub marks when adjusting the brake. The front shoe won't center itself either like the right rear shoe does. Also, the front shoe doesn't adjust correctly. The adjusting cam needs to be backed off way to much for the shoe to come off the drum. That's why I think the brake shoe return spring is weak because the shoe is hanging up and not returning. The brake support plate is also suspect because the shoes could be hanging there when returning.
Wayne Graefen suggested replacing the front hoses. I will. It seems the inside of a hose can break down and prevent fluid from returning to the master cylinder. I heard that from others too.
Joe McCormick gave me a lead on return springs from Northwestern Auto Supply in Grand Rapids, MI. I'll call them first thing in the morning.
Any other comments are truly appreciated. Sorry this note got so long.

It was said at one time that the late 60's - early 70's cars had a heavy
duty brake spring, exactly like the 57 spring. MIGHT be another source
to ask about!!
BUT I think there are a fair number of folks that would be interested in
a possible source today!

If there are any members that are thinking about rebuilding there 413
engines. I just bought a new set of Federal- Mogul Pistons for $ 61.12
for all eight. They only have .030" oversize. and 9.7 to 1 compression
ratio Thats about a $ 250.00 savings over most suppliers. I just
received mine today. I bought them through www.rockauto.com
. They also carry other 300 parts of all years.

Probably tool chatter from a bad setup on the part of the lathe operator or
something like a dull bit. Hard spots in a drum show up as islands in the
braking surface and does not sound like you have this condition. Drums with
hard spots must be ground to restore the braking surfaces. Finding someone
to grind drums may well be as hard as finding a brake lining arcing machine
(which BTW have big vacuum cleaners attached to catch the dust; oh, yeah).
Hard spots are noise makers.
I do not have the drum IDs. Hopefully they are both the same.
I definately like the diameters to be equal (replace drums in pairs) but
have seen .030 difference side to side and no problem.
There is clearance at both ends when centered in the drum. I'll have to live
with that and "break the shoes in".
There should be, must be clearance at the ends with the shoe centered on the
drum braking surface. This relationship is what the cam grinder does (when
the shoes are relined). The lining should actually rock but slightly.
Clearance should be something and up to .020" and do not try to make it less
as brake lining will seat in just fine and very quickly.
I noticed that the right front brake shoe contacts the drum at the top end
of the shoe (rather than the middle) when installed. It can be seen by rub
marks when adjusting the brake.
This is exactly what will cause uneven braking, grabbing etc. This is why
brake lining must be ground with clearance. If your shoes fit the drum
properly off the car and are hitting on one end or the other when installed,
there is a problem with the installation of the shoes (etc) on the car.
The front shoe won't center itself either like the right rear shoe does.
Also, the front shoe doesn't adjust correctly. The adjusting cam needs to be
backed off way to much for the shoe to come off the drum. That's why I think
the brake shoe return spring is weak because the shoe is hanging up and not
returning. The brake support plate is also suspect because the shoes could
be hanging there when returning.
There is a good product to use where the shoe rests on the anchor and where
the shoes rest on the backing plate. It is made by CRC; Sta-Lube Brake
Caliper Synthetic Lube. A little bit will work wonders at letting shoes
return properly providing that backing plate surfaces are super smooth, flat
and clean. Needs to be used on anchor also and too much will screw up brake
linings.
There are some truck brake configurations that benefit from using the brake
pedal to center the linings in the drum during adjustment.
Wayne Graefen suggested replacing the front hoses. I will. It seems the
inside of a hose can break down and prevent fluid from returning to the
master cylinder. I heard that from others too.
Joe McCormick gave me a lead on return springs from Northwestern Auto Supply
in Grand Rapids, MI. I'll call them first thing in the morning.
New brake hardware is cheap and with a big positive payoff. New hoses; the
same. ALL the hoses BTW.
There seems to be a list of problems with the front brakes on this car but
the rear brakes can cause pulling also.

Hi All,
I spent some time playing '63 horn repair this weekend and have reached a dead end. Everything in the system tests fine until I get to the steering shaft. It doesn't provide the ground that the relay needs. If I take the horn ring cap off and ground the shaft, everything works great. Put a meter on the shaft and I get no continuity anywhere. Anybody had this problem and if so, got a solution they'd care to share?

Hi Russ,
Sounds like your problem is with the copper grounding strap that provides
ground to the actual shaft itself. This copper "sheet" wraps around the
rubber steering insulator that fits between box and shaft, and grounds the
shaft to the box.
Solution is removal of outer jacket of steering column, and examination of
the end of shaft where it meets box. Probably a good idea to replace the
rubber steering insulator same time, as it is probably shot or falling
apart...

Horn;
Russ I had the same problem after taking the outer shaft off about ten times. I discovered the reason there was no ground was because the wire that attaches to the steering wheel copper ring, was in fact broken . I tired to re solder it but it broke again in a day, so I drilled a small hole were it attached to the copper ground on the wheel and it has worked fine ever since . There are only two grounds on the wheel and at the end of the shaft . If both are at ground it has to work.
