Re: [Chrysler300] 1958 300D Brake shoe lining

I agree with Gil about total contact brakes. 

On my 3rd set of 62 brakes, I did everything "by the book" and they work as new. 

The Sport Conv. had little use for 30 years and the leaking DOT 3 fluid had done it's job of corroding nearly everything. 

I removed, cleaned, painted and or replaced everything including all cylinders,springs and backing plates.  

I replaced or turned all 4 drums and most importantly had the new shoes "arced" to fit each drum. 

I then purged the steel lines and am now using DOT 5 silicon fluid. 

By the book adjustment was easy and no pulling to either side has yet been experienced.

Thank you, Henry. That is exactly the idea of the Chrysler Total Contact 
braking system introduced in the 1956 MY and continued thru 1962. I have 
heard all the complaints about them, but when set up properly, they work 
fine. (They are somewhat---some would say very---particular.) I remember, 
while at Chrysler, talking about that with an engineer who was in the brake 
lab at that time. He stressed the importance of everything being set up just 
right. Now, if only Chrysler had combined the two leading shoe idea with 
Buick's great finned aluminum drums.....

Note that for the 57 models, the front brakes have two leading shoes. 
That is, both get pulled into the drum with the car going forward. It doesn’t 
matter that one is upside down. The rear has leading and trailing shoes. 
This gives more braking torque on the front than rear, as it is needed. 
Later cars with leading/trailing shoes on the front and rear generally used 
different sized wheel cylinders (or drums) to give the necessary brake bal 
ance. Also note the 57 Chrysler workshop manual clearly shoes all shoes 
front and rear have a full length lining. You could probably get away with a 
shorter lining on the rear of the rear brake but I wouldn’t do that on the 
front as they may get hot at different rates leading to earlier fade. 
Suggest you look up a 58 manual to check.

Not sure if 1958 shoes are any different but whenever I purchased brakes 
shoes the set usually had two shoes with the lining on the Whole shoe and it 
also had two shoes with the lining ending an inch or so before each end of 
the shoe. 

The shoe with the shorter lining goes on the front half and the shoe that 
has Full lining goes on the rear half. I did an internet search to verify 
this and it's shown below. 

Where does the bigger size brake shoe go front or rear in drum? 

The smaller shoe should go on the front. The larger shoe should go to the 
rear, but not because of why you might think! 

When the brakes are applied the front shoe tries to jam itself into the 
brake drum. It is that front cohesive part that has the strongest braking 
force - pressing most-so upon the forward-facing shoe. However, even though 
the front shoe is where the majority of braking force is applied, it does not 
get the larger shoe! 

As noted, in a braking mode, the majority of the force that the 
decelerating vehicle applies to the brake shoes is applied against the forward shoe 
by the forward-most area of the inner brake drum, this makes the forward 
shoe the stronger, braking-wise. To help even things out, the rear secondary 
shoe is designed to be larger, to more equally match the braking power of the 
smaller, but more powerful front primary shoe. 
Ergo: The proper place for the larger shoe is to the rear.

Could someone tell me when relining the brake Shoes 

Should the lining cover the whole shoe? 

The reason I ask I,s I have purchased re-lined shoes from different 
suppliers 

>From one supplier the lining covers the shoes completely & the other there 
is almost an inch at each end with no lining 

Thanks
