brake springs - 57

["Vath, Michael J." <mjvath@xxxx>]

Using the eyelets worked fine for 7 of 8 C wheels...
On the front driverside of my C coupe, however, the persistent squealing noise Phillippe mentions was the eyelet-mounted return spring coming into contact with the inside ridge of the brake drum! Wider shoe? Mis-shapen spring? Worn bearing? I replaced everything, but ended-up simply bending the shoe eyelet ever-so-slightly to make the squeal/contact go away. Just a few taps to move the spring inward was all it took.	Its now quiet, and the brakes are very strong. Moving the springs to the inner mount would also work, but is difficult to do - and would seem to provide slightly less spring stretch.
No problems so far....it stops very well.

The T-code coupe is to make its grand debut at the 700-car Canton, GA cruise-in this Saturday -- about 5 miles from the chicken coop it spent the last 25 years in. Rain forest weather permitting, that is.

Hi John,
It's a question that i ask myself since a lot of time !!! The (US) ' 57 
FSM shows that FRONT springs are anchored through the hole of the shoe 
and not through the eyelet (fig 57x48, 57x49 etc..). The REAR drum 
spring are anchored through the eyelet (fig 56x177A). Note that front 
springs have 4 coils and rear have 5 coils.

BUT, on canadian 57-59 Mopar FSM: " insert the 4 coil (5 on rear)) 
return springs in the hole in the brake shoe webs". Two pics, the one 
showing front brakes (fig 1408-57) with spring throught the hole and 
another pic showing rear (fig 1409-57) with spring in the eyelet !! Next 
page the rear spring is in the hole of the shoe (fig 1410 or 1411-57) !...

Who knows what is the correct mounting ?

On mine i have anchored the FRONT springs in the eyelet since my 
restoration and i posted this yesterday on IML :
"Today i drove my car in a lot of "stop and go" (2 miles driving with 
several braking then stopping, then go back 2 miles, then stopping 
etc.. ) and i notice after 2 or three travels that front (drum) brakes 
make some squealing noise when i brake a little hard, especially when 
the car stopped. After another 2 or three travels, the noise increased 
and came sooner and also every time i brake the car . This noise is like 
the one you've sometimes on disc brakes or the same than when a train 
stopped at a station !!! Then i stopped the car for 1 hour or two. When 
i took again the car, no noise when braking... But it came again after 
20 or 30 braking ..
The noise came from front (left i'm sure but it seems also that right 
drum makes noise) not from rear... The braking (except the noise) is 
correct. "

I just wonder if ther's something wrong with springs anchored in the 
wrong place !!
