Squeaky Drum Brakes & A Terrible Mechanic.
« Reply #150 on: April 08, 2021, 08:21:40 PM »
New update.
I ordered Dorman cylinders and they sent Wagner’s. They fit- almost... I needed to grind the top of it ever so much for clearance to fit.

Cleaned up the backing plate nicely too.
But noticed the bottom two landings have a nice little groove in them... Can I still get more life out of the backing plate?

...Check the shoe lands ... for deeply incised grooves and, if necessary, sand them just enough to remove any abrupt edges that may cause the shoes to catch.  Smear a dab of white lithium grease on each of the lands...

Thanks guys.

Good to hear to still use them, as I just discovered the same on the drivers side.

Sanding them isn’t getting me very far, but they’re sanded for sure.

But they’re by no means flat.

Use a sharp mill file if you have one followed by 80-grit paper.  A better method is to use a 60-grit sanding disc to touch it up.  Just make sure there are no lips that can trap the edge of the shoes.

I suppose a metal grinder would be over kill...

I have a sander, but only 150 for it at the moment. I’ve been using coarse emery cloth at the moment.

I don't know, with a closer view, look like you might want to do something.

Well, per bd, you don't want them to catch, but it doesn't look like there are any burrs or ridges.

Couple of fixes: A: Weldy weld, grindy grind smooth. B: Braze and fill, grind smooth. C: JB weld, grind smooth.

Maybe B & definitely C would require removal of the plate so as to apply work to a flat surface.

In the grand scheme of thing, your brakes are going to ignore those grooves.

That's a wood rasp.  Good luck using it on steel.

I’m gonna be burning the midnight oil assembling the brakes- I’ll post pictures to confirm my assembly when I’m done.

Yet, one last question for the evening:
In the picture, from bottom to top- outer lock nut, ‘tab lock’, inner lock nut, and.... what is the forth piece?

I only had one on the drivers side, not the passenger side. Is it essential?



So, after I finish assembling these brakes, bleeding the brakes and posting final pictures to confirm, I'll be looking to get the drum on for adjustment, before the tire.

Question still remains... This forth piece I have for the drivers side, do I need one for the passengers side? If so, this is gonna put me another two days behind schedule.

Haha- believe it or not, it did the trick.

There’s a groove, but less of one with no significant lip!

Be aware that filing them smooth lowers the plane the other lands are on. In other words, the shoes will not touch those lands.

Better to fill and grind smooth or just leave them alone.

I would run them...

It's a keyed spacer between the bearing and the first adjusting nut. Originally came one for each side. sorry... ::)

You can pry get away without it, but...

It doesn’t fit snuggly against the bearing though- it floats around.

I missed it when I originally disassembled everything, and then it fell out of the drum a day later when I flipped it over.

So, you’re saying I need another one?
Don’t happen to know the part number do you?
