    Ughhhhhhhhhhhh

    I'm ready to pay for a fix because I'm so over it . Haha.

    My front drums been rubbing so bad I finally figured out it was the backing plate. Got one from ebay and I'm very happy. Whole thing went smooth, bled them out..no more noise.

    But wait... Rub rub rub.. Rub Rub rub.. Now I can hear the rear!

    Took off drum... Broken shoes. Bonded became unbonded. No wonder grandpa always said get the ones with the rivets. ‍♂️

    Had the shoes laying around.. Put them on... Drum don't fit. Okay... Adjuster all the way closed.. No go. Parking brake not stuck... No go . Opened bleeder tried to push wheel cylinder in further... No point , top of shoes already as far as they'll go.

    No idea.. Old and new shoes look good to the eye.. I ended up putting the shoes on without the adjuster in there. I had to move the car. I guess I'll try a new wheel cylinder and adjuster just in case.. But that was frustrating..

    Anyone else run into this tomfoolery?

    TrunkMonkey Totally bananas

    You sure you have a front and rear shoe and not a pair of front shoes?

    What material are the shoes? I had an issue with some semi metallics several years ago on my 58. Bought organics and the drums fit over them better

    They're Bendix RS340, supposedly organic...

    With a fresh mind this morning I feel like I'm going to show my work to someone and they're gonna point out something dumb that I missed.. But I dunno..i took pictures of everything before I removed the old shoes just to be double sure, and it all looks the same to me!

    Maybe put a fresh turn on the drums if there is enough meat on them. Also check the show to the drum itself before installing to make sure the arc is the same. It doesn't take much for them to not work right, or at all.

    I've posted the originals..


    Right now I'm doing a bit of cooking for the holiday and I won't be able to get a picture of the new ones today.. But now I'm thinking.. Maybe it is the shoes.. On the new ones, the hole where the adjuster attaches wouldn't accept the hardware and I had to drill it a little.. It wasn't round, it was oblong. Just off a hair tho. But maybe that means the quality stinks. I do like that the new bendix shoes are powder coated, but that don't mean jack if I can't install them!

    since the old ones are the example I mimicked maybe you guys spot something that was wrong the entire time

    There sure isnt much meat on those shoes. The fronts are about 1/2" wider than the rears. I ran into that with a box full of shoes from the motor parts. Rear drums wouldnt seat since the fronts were wider. DUH. The things that you forget. Being listed on the boob tube at the parts store,companies sold and parts reboxed with lazy kids shelving the parts and picking them for the counter doesnt mean theyre gonna be correct. Compare the old ones side by side with new ones.
    Most of the junk today is bonded. Bonded AND riveted is a bit harder to come by. Its all about due diligence on the consumer. Poor repair shops hafta eat the labor on wrong parts all day long. Chinaman be raffing allll day long! This shows the '64 fonts, after sitting since 1980. OEM B&R shoes, leaking wheel cylinders, and OEM wasp nests too. The bottom pic is B&R rears off the '72. ws

    I ended up kicking the drums on with both feet... terrible idea in practice, I know... but since the last shoes went metal to metal i figured a little rub for a mile on organic wouldn't be so bad.
    I drove it around less than 5 minutes up the street about a mile down and a mile back... it smoked a little...... since then no smoke and good stopping with no noise and now it's easy to turn by hand.

    I DID end up finding Raybestos shoes that are bonded/riveted and when I get the drums machined I will be putting those on properly.

    I'm going to chalk it up to crappy brake shoes made in China. They were just a little off all over the place but at least I can go down the block now and stop and have no lockup and no smoke.
