Pulled the right rear drum to find a lip of about a millimeter and a half on one side tapering to no lip on the opposite side (other side different brand drum and has no lip all the way around). What would cause this uneven wear?

The drum is stamped made in Japan and has no oil passage. Should the drum be replaced?

Thank y'all in advance! Smile

Can you get a picture, do the brakes pulsate . The drum may be savable, it's tough to find good new brake drums.

Tried to get a picture unsuccessfully, any tips?

Not sure if pulses, hasn't been on the road since 2002 or 2003. Drums are available new. Consider rather be safe then risk, why replaced all the hard lines as were rusty and didn't want to risk a leak on a single circuit system (have lost the rear going down a grade and wasn't fun). Now that think about it, wonder if could mount it on the axle and check the exterior and interior runout? Been meaning to invest in a guage as need for setting front bearings on another vehical. Just a thought...

are the rubber lines new? old lines will cause shoe dragging, insides degrade and act as a check valve, after replacing several sets of shoes, while bleeding the brakes again i noticed the line bulging while assistant was pumping the pedal.

Would guess the tool/spindle the drum was installed on to lathe the inner diameter at the factory was somehow off. Maybe a metal chip stuck in the dead/live center end. Would not worry about it, now that it has been trued up with the actual brake shoes.

Well, got the drum on, and where the high spot is, even with the shoes all the way in, rubs. What you make of that?

Are the shoes not sitting square to the backing plate?
Is the backing plate bent?
How well do the ends of the shoes fit in the slots in the adjusters and wheel cylinders?

I somehow missed this reply until attempting to combine the threads per feedback into the build thread (https://www.thesamba.com/vw/forum/viewtopic.php?p=9283462#9283462), how about replying there?

In summery, all seems to fit, so once driving, will keep a feel for pulsations, then will replace the rear drums.
