new brake drum locks up wheel [Solved]
 

hello jeepers,

last summer i had replaced my rear brake pads on my xj 88 including hardware, this all went fine but i knew i had to replace the brake drum and i just did this with a brandnew brake drum. after taking off the old drum i losen up the adjuster so the pads would retrack and this worked fine. now after installing the new drum and the moment of tightening the lug nuts the wheel cannot be turned by hand its really tight.. seems like the tighter the lug nuts go the tigher the wheel is. its still sitting like this right now i moved the jeep back and forth just a few feet but didnt take it for a drive yet.
is this a common problem with brandnew brake drums ? does this have to wear in or is there something wrong ?

[edit] when backing the drum off a tiny bit its not that tight anymore.. seems like but not sure the backing plate that holds the whole brake assembly is too thick ?.. seems like the studs need a washer on each of the five in between the drum and the wheel studs .. could this be right ?? im just guessing here

thanks marc

What model rear axle you have? Maybe the wrong drum.

i have the dana 35c none clip

Have you compared it to the old drum?

i put the old drum on the new drum facing each other with the insides and diameter was the same .. i layed them flat on the carton and both seem to be the same height
i didnt measure the inside but by the looks of it it seems the same except from the part that is worn of course in the old drum

You had no problem until you replaced the old drum so I'd think the problem would be with it. Maybe try the old and new on and see how they compare in reference to the backing plate. Wouldn't happen to have the part # for the new drum?

its the 9inch one cause i needed the smaller 1 3/4 brake pads not the 2 1/2 .. so i think the 9 inch should be the right one

these are the brake pads/shoes i put in last summer

According to Rock Auto the only 9" is for the Dana 44. Even the 1 3/4" they list is 10"'

And according to O'Rileys using your link they don't offer a 9" drum.

here are the picture of the old drum, when i look at the cooling ribs they seem the same as the one i ordered, the rib on the 10 inch look bigger

ive been driving around with the wrong drums for 6 years (this is how i bought the jeep).. hmm .. this is confusing to me as heck

hmm.. i see your link.. so that means i did buy the 10 inch 1 3/4 ones .. then it should be the right drum right ?

[edit] sorry i am so confused.. so both oreilly has the 10 inch 2 1/2 and the 1 3/4 and ive ordered the 10 x 1 3/4 .. there is no 9 inch .. i thought 10 inch is 2 1/2 and 9 inch is for 1 3/4 but i was wrong.. so still i do have the right drum

For some reason O'rileys doesn't list the drum diameter used with the #267 shoes. But they do for the 2.5" wide #481 shoes and it's 10". Same brand to.

Plus the only 9" drum that Rock Auto shows uses 2.5" shoes.

Have you measured the width of those shoes?

Did you get the drum at O'Rileys?

no i didnt meassure the shoes, i had two packages last summer and the smaller ones matched the once that were on the jeep so i returned the bigger shoes.

and yes i bought the drums at oreilly's few days ago.. i only switched one drum cause i am still waiting for a park brake cable for the other drivers side and wanted to do this all at once.

i have to say 'thank you for your quick replies sure appreciate it'

so im not sure if the drivers side will give me the same problem yet.. just wanted to be sure i have to right drum i think they wont take it back if its used or scratched

It's really hard to diagnose a problem when you can't get your hands on it. LOL I'd be trying the old and new drums on with lug nuts but no wheel to see where they each sit in reference to the backing plate and if each still turn. I'd even go so far as to remove the shoes and try them. Just sounds like a mismatch of parts somewhere. Also I wouldn't mess with the drivers side unless it would just be for visual comparison.

Just a thought. Did you replace the wheel cylinders?
