Title: Drum brake issues
Post by: Dfalca on April 15, 2018, 21:18:15
Hello pagoda world,
I am working on r rear drum brake 67-230sl. Removed shaft checked seals and bearings and put back on. Reassembled everything (replaced brake cylinder that bleeder valve goes into).  Now that I feel it is good to go I place the hub and tire back on and it grinds to a halt. Meanwhile the left side rolls perfectly. I have a few questions because my frustration is high.

Did I smack the axle in too much? It seems like it is 3-4 mm “deeper” in than the left side.
Is it the drum pads? I believe they are pulled together as tight as they can go, but I am not sure how to check this?

What is grinding? It doesn’t seem like it is the pads? Once the tire is on tight it won’t move at all.

Ugh, I don’t want to take off the whole assembly again, but if I need to I will.

Can the shaft be pulled out a few mm without taking apart the backing assembly??
I feel these few mm may make a difference in whatever is rubbing.

All advice is welcome.

Thxs
Dave

Check the order that you mounted the brake shoes in. There is an inner and outter and you need to make sure that they are pit on the pivot in the correct order. I had this same issue and it caused grindning on the outter surface if the drum.

I agree with George.

I matched it up to the driver side, but I can switch this pretty easy. Is it possible that I put the shaft in too deep? Or does the bearing prevent that? The tire cannot even move when reassembled.
Thank you for your advice. I'll give it a try.

I think it should be opposite the other side. Look at the off-set at the hinge point of the shoes. I don't think it is possible to drive the axle in too far.
