Rear drum brakes, replacement discrepancies...

Malicious · Apr 13, 2016

Hi, got some replacement shoes and drums for my 68 8 3/4 rear end. The shoes I have, have a few differences so I thought I'd check here before I do attempt the install.

Pic below: the first thing is the top hole, which is a cross between a square and a circle. I've pulled the park brake lever off the old shoe, I assume it should just slot into the square/circle, but the hole is slightly undersized. Am I fine to give it a light file?

The second thing is, one shoe from each pair has a lower peg, which my current don't. Are these just not used for my application? Or is the a new way to attach to the park brake cable?

That's it, thanks for your help!

the top hole looks like for later models that slip into the hole rather than older clipped types for the emerg lever. I can't imagine filing the opening would hurt anything.
I'm not sure about the peg but I'm thinking it's for later model adjusters.

Thanks Glenwood, I wasn't sure if the metal was spring or tempered etc. I'll give it a light file to get it in then.

So the post is in the bottom right (or left) shoe on your pic. My brakes look very similar except they don't have the spring on the wire 'stabiliser'. Is that a newer thing? Pic from before I rebuilt the first time below:

The pic is from later model mopars but I'm not sure from what model. I thought the shoes are basically the same although the openings look a little different but seem to be in the same place. I hope that helped.

I don't know how you're going to attach your e-brake leaver? I would take them back and have them pull another set or try a different set for a year or two older vehicle.

Thanks guys, very light file got the park brake lever in easily. Also a light tap with the hammer got that peg out, so good to go.

I did notice during assembly that the boot has basically a pin hole it it with a little bubble/froth when moving the cylinder in and out. I think I might have caused the pin hole by pinching the boot slightly. I removed the boot and there was maybe a drop lush of brake fluid in there.

The cylinder is new hardly any use although I brought them 2 years ago they would have had maybe 50-100 miles put on them.

Is this level of seep normal/with in tolerance? Or should it be 100% dry?

Just wanted to check before I decided either way. No point stressing if it is normal, also no point assembling if I need to replace the cylinder.

Cheers

I don't think so. Sounds like a bad seal on the cylinder. just my opinion though...

I believe they are supposed to be dry, I had those same good ol' made in USA ones you have and had to replace both rears in 3 years. They totally gunked up my brakes which is how I noticed something was amiss. Replaced them with some Chinese ones, can't remember the brand so we'll see how those ones hold up. Made me sad that I had to take off USA parts because of premature failure.

Thanks guys, luckily the local had a replacement, that's amazing because I'm in Australia. Thought I might have to wait in a parcel. All good now I think.

Suppose to be dry. Otherwise, fluid will get all over and more importantly, on those new shoes.

Thanks mate, figured that would be the case. Or at the least, I'd rather play it safe so changed it up.
