Re: {Chrysler 300} 300F brake dragging



hi master would have nothing to do with it ? 
The fronts are fussy 
If not driven a while , drum can get rusty , causes aggressive self energizing , as in face hits window in spring . Took apart brakes myself for nothing a few times long ago,  an old timer ( me now) told me -- if that problem , other wise were fine ,  brake car  aggressively in reverse a few times cleans  it off     
Was it ok? 
If a "real " problem / new brakes , shoes are often not the diameter  of turned drum  (Often turned for nothing other than " have to do that ")  ( opinion ), makes drum too big for shoes , = grief for 1k-1.5!k miles . It is ok if drums are scratched , new pretty ones will soon be 
They used to arc grind shoes to match within a few thou . Cannot find that today .  I never turn drums now  
Or , a mix and match wrong shoe designs / backing plates , different " platform "   complicated by aftermarket shoes intended to fit both designs ( that got me)  this changes springs and attachment places   
I assume you have excellent service bulletin on setting up brakes ?-- tells you about all this, Mr Merritt may have on tech section ?   
They are ok once " dialed in "or " "worn   in " . Leave alone if half used . Not going 100k more, just brings you grief ( mho)!

Your photo doesn't show the brake shoes or the surface of the drum.  If there is any contamination on the surface of the shoes or the drum face, it could certainly lead to the symptoms you are describing.  Also, I can't tell or remember if the shoes are supposed to be equal length, or if there is a specific 'leading' and/or 'trailing' shoe, but I'm sure there are experts on the server who do remember.

After repairing a leak at the master cylinder and bleeding my car would pull to the right on braking.

Then on my last trip my right front brake remained engaged after braking.

Fortunately I was a few blocks from home and was able to continue slowly.

Here is a photo - I expected to see a broken spring but everything looks normal. Both wheel cylinders extend and retract when I lightly press the pedal.
