RE: [Chrysler300] 1958 300D Brake shoe lining

["Henry Schleimer" <henry.schleimer@xxxxxxxxxxxxxxx>]

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 balance.  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.

 

Regards

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
