DRUM Brake Overhaul - Now, for something totally different...

Don't under stand why your pumping the pedal. I used Dot 5 in my new system. Manual brake's half pedal before brakes engage but stop's firmly. But every thing is new on the car. Have you replaced the master cylinder. Could have a leaky valve.
Since yours engages "normally" at half pedal, can you do me a favor and next time, pump them once and
see what happens?
Thanks!
 
Note to self: The factory wheel grease dust cap part number is 1613416.
New arrivals in the mail today:

Them's factory parts, y'all - but from what I've seen, they're going fast!
Dorman has already stopped making them and after the factory stuff is used up,
we're stuck with that Chinese repop a lot of the usual suppliers sell.
I can't comment as to the quality of those, but I can say these Mopar ones are
as thickwall as ever. :thumbsup:

Interesting tidbit with the dust caps:
I could not find ANY replacement dust caps locally the other day, Chinese or otherwise.
We dug around at Advance Auto and came up with something that is close to the same
diameter, but when I tried to install it later, it wouldn't seat all the way down to the flange.
It's on the left here:

When compared to the Mopar new one on the right, the height is readily apparent obviously.
"Ok Ed" you say - "obviously the crap cap on the left was bottoming on the spindle itself."
Well, that's what I thought also - until I just went to swap it out for the Mopar one...

The new Mopar cap also refused to seat all the way down to its' flange, much to my chagrin.
It's obviously not bottoming on the spindle, so what is happening here?
Turns out...the race for the outer bearing in the hub, despite being seated all the way against
the stop in there, still impedes the cap from plunging all the way into the hub opening.
The race bumps heads with the cap, in other words.
No idea what to do about that, short of replacing the race/bearing - which I'm not inclined to do
right now.

I seated the Mopar cap as well as I could with a deadblow plastic-coated hammer and called it good.
We'll see...
 
Got the flat cap's at O Reilly auto parts. Seated to the ring on the dust cap. But had too bend them a little so the would fit snug.
 
What about the caps from Bill Rolik? I keep kicking myself for not looking at his stuff first. Got a great set of strut rod bushings and ends from him and could not find anywhere else. Here are his grease caps:

Those are the "Asian" repro's I mentioned that many vendors are offering, yes....
and they're not going to certainly be any better than the Mopar ones I now have (and installed on one side).
Oh...and for at least right now this minute, the Mopar originals I just bought are even slightly cheaper than those. :)

Fair enough. I’ll make due until I find oem stuff.

Easy peasy - right now, anyways.
Rick Ehrenberg has a few (where mine came from). He's on eBay under the username "rehrenberg".
Less than $15 each + a little shipping, but you best hurry.
 
My noggin is probably not all the way on, but the rt. pic doesn't look good. TOO tall, but I defer to more knowledgeable members. Maybe just the camera angle? Mine (oem) look more like left side(?) Agree to disagree.

You may well be right, but what I got is what Mopar was selling for all 57-72 (except 9" drums
on Darts) - and honestly, "too tall" doesn't hurt a thing to me, even if it is.
The original Mopar part number is 1613416 - but I wouldn't swear Ma didn't do some parts consolidation over
the years.

Here's the repro from Herbs:
https://www.herbsparts.com/proddetail.php?prod=1613416
(Notice they reference the exact same Mopar part number I just bought 2 of - as do every other supplier I've
seen).
It's pretty typical of any of them I've seen.
They fit inside my Magnum 500's and they are nicely finished. I'm happy with it.
 
UPDATE JULY 4TH!
(And this one is an "Ed story", so you've been warned!)

After a busy Friday capped off by the first actual Cruise-In of the year (the first couple have been
rained out), Fred got some miles on him - enough that I decided it was time to finish this project...
once and for all...
one way or the other.

What was left, at least in my estimation, was the follow-up check/possible adjustment of any shoes
and more importantly, determining the status of the fluid in the system (and subsequent bleeding that
may or may not be needed).
When I awoke at the usual 2-something AM this morning and the right parts of me ached, I knew it was a
good day to roll around under Fred - I mean what the hell, they hurt already right?
Might as well give them a reason to...:icon_fU:

I started off by informing my wife I was going under the car and not using jack stands, figuring the wheels
staying on performed that function, right?
She took it another way though - "I best get out there, he's about to do something stupid again".:rolleyes:

After consulting both John @khryslerkid as well as the FSM, I determined kinda in between that if the brakes
showed any drag at all when the wheel was spun, it was good and to leave that part be - which they all did -
which I in turn did as well.
All seemed to be fine functionally...at least from the outside.
(Yes, this is foreshadowing - insert dramatic pause here).

Next, I grabbed the MightyVac or whatever that thing is and decided to one-man bleed things to have a look
at the fluid (which had less than 1K miles on it, far as I knew). The master cylinder and all the lines had been
replaced years ago, right before I bought Fred - but there was little actual mileage on any of that.
But...
When I found a freaking METRIC bleeder screw had been forced into the RR wheel cylinder by someone before
me though, things sort of went left field - in a hurry.:mad:
It turned out, the bleeder was 7mm (or 9/32 if you like). Sumbeech, I got no box or open-end for that size...
only sockets.
Oh well, get the thing loose and hook up the suck-n-vac, then finish off with a good old fashioned two-man
(or man-wife) operation, eh?
Yeah, well....about that:
The moment I opened that bleeder, then attached the vacuum jobber, the fluid that came out was MUD BROWN.
Not a little dirty....not even moderately filthy....but MOCHA, man.
frustrated.jpg
I gave my wife a quick refresher course on manning the master cylinder/fluids and as she kept the master full,
I kept pulling nasty, rotten fluid through the line.
She accidentally let the reservoir go dry once, then proclaimed from the front of Fred "it's NASTY in this thing,
too!"
Well, of course it was....so she took a paper towel to it until it was clean inside as well, then we resumed...
and eventually, clean fluid emerged from my end of the circuit.
Hallelujah.
We then bled....and bled....and bled, with me and the underside of Fred eating some premium petroleum
products and she proclaimed the pedal good.

Figuring the drivers' side would be similar, I tossed all the miscellaneous toolage to that side, then just rolled
like a log over to that side, rather than get up.
The wife started to make a joke about calling Greenpeace for help. I "AHEMED" her out of that notion, real
quick-like. :blah:

I was greeted on the drivers' side rear to *gasp* a normal-sized bleeder screw!
Naturally, this meant all the tools I had under there now didn't fit.
So much for not climbing out of there...*sigh*
I'm getting pretty nasty at this point. The wife is only growing more bemused.
Ol' "Phoenix risin' from the ashes" dug out the right tools and set back in there....and things went much
better this time!
Woah hold it....now the wife pronounces the pedal has gotten worse. MUCH worse.
:mad:
Up I climb again, back to the bench, fetch the metric crap, back under the passenger side again.
Wife fills the master again and we bleed the RR - AGAIN.
First time, wife now announces the pedal is ROCK HARD.
Well, far be it for me to question her judgement on such a thing, right? :lol:
Why it took that sequence to get it to that point, beats me.
It just did - this time - with this car - and this floundering walrus underneath it.

From there, things went quite routinely at the front sides. Both ran clear pretty quickly and bled fine and
the wife kept saying "you're not gonna believe this pedal!"
I purposely ignore that and instead cleaned up everything, put it all away, checked for leaks, refilled the
master - anything but step on that pedal myself.
Why? Morbid fear, I imagine. I was too nasty, pissed off, sore and hot at that point.
She takes off for the house, dog in tow, headed for the a/c - and THEN I headed for the brake pedal, half
expecting the worst.

*sigh* "Ok Fred, what you got for me?" *flinch*
Hit it - and that pedal was, indeed, "rock hard". :eek::eek:
Hmmm.... ok, went off to clean up some more and came back a few minutes later....
Hit it again - and that sumbeech is STILL high and firm, first pump!
I'll be damned....
I head in to the house and she gives me that look of anticipation, wanting to see me happy from all the
wrestling that has just occurred - and I won't crack a smile. Nothing.

I go wash up in the kitchen sink, just like I've always done since I was a teen in mama's kitchen, using
dishwasher liquid and a scotchbrite, staring out the window - and remembering.
I've always done that because I saw my Pop do that, time and again, when I was growing up.
It's just something a kid grows into, emulating his dad... doesn't even think about it.

It also occurred to me then that this was the end of the brake project - and probably the last time I'll ever
attempt such a task
- and it actually had turned out as well as I had hoped it would.
I did give my wife the satisfaction of my grinning in satisfaction - but she saw the melancholy in my eyes, too.

Thanks to everyone who followed along with me in this nonsense - or takes the time to read it in future
years. As you can see, it wasn't just an exercise in working on an old car - but it never is really, is it?

Thank you Lord!! Still waiting for couple month report on brake shoe efficiency. Jeff
 
WHEW! Glad it all turned out good after all the hard work you did. Keep us posted as to how it's all holding up from time to time. This is/was a great thread!
:usflag:

You and me both, sir. We took Fred to town to run a couple errands today and the pedal position did settle
a bit with usage - probably has about an inch and a half at worst travel now - but pumping makes no difference,
which tells me the bleeding was completed.
The shoes are already biting pretty good and will only get better as they cut into the old, hazed over drums.
Good enough for my wife to fuss at me for allegedly attempting to head butt her into the dash, anyways. :)

You're very kind, my friend. You've been very supportive the whole way and I do appreciate that a lot.
I reckon the only thing I could do to improve the brakes now would be new drums but really...with these
old ones still sort of in spec, would new ones help much?
Probably not.
 
I bet Wife's right leg is stronger than the left after all of that! :rolleyes:

You have a good woman there that gets involved and is not afraid to get dirty. And actually understands what's going on! Rare find for sure :)
 
Well, a couple days later

Update to this:
After much research on the proffered brake shoes (I now know way too much about the codes stamped into
brake linings - sheesh!) as well as actually contacting the suppliers' tech line, the shoes are indeed China-
sourced, regardless of who the American retailer is here who sells them.

I've been told by said retailer that "nobody makes brake shoes in the USA anymore, hasn't for years"....
as if that makes it better or easier to accept.
Well, at least for me - it doesn't.
I'm not quite ready to accept defeat on this just yet - even if it means my eventually buying "inferior" old
(but new in box) linings to use.

Remember the point of the exercise - I want to see if it's still possible to do a basic "brake job" on Fred's
factory-built drum brake setup using all USA-made parts.
To be continued...

Hey @JG71B -
Just curious as to what you disagreed with in my post above?
