[Chrysler300] Re: 12 “ total contact front brakes

It has been a few years since we did the 300C and 300D so I don`t recall specifically what was the difference between 57/58 and later 60/61 brakes , we did a swap to 60/61 brakes on a C or D and yes there were some stuff that was different between the two . Once I get the D back from the paint shop, I can check visually what is different between each type of brakes, I can compare between my F coupe and the D. D will not be back in my shop for a few weeks though...

Hi , I did not state this correctly , sorry , additionally meant to ask if rear brakes/ shoes mounting etc follow the front shoe changes ? And the when ?

Involves I think contact pads and / or vees that hit on backing plate “ bumps or pads” so backing plate changes ? Also small retaining pins and springs from backing plate move too , holes in shoes are in different locations . Possibly large spring too .

This info may exist in service bulletin or something ? I seem to remember seeing it ..?

Sorry for double mailing,

John

Subject: 12 “ total contact front brakes

Hi ,
Need some help or advice ; JY mentioned to me in the past some issues around how the brake shoe return spring is attached to the shoe , such that different ( and apparently not interchangeable) 12” shoes exist ? There may be other differences too ? I have a pile of 12 “ brake parts , probably like many others , and trying to assemble compatible 12 “ pieces .
Is anyone familiar with this and when it changed — and differences across the years before Bendix ?
Thank you ,
John
