Default rear brake drum removal

Ok, tire is off, drum does not come off. It spins freely, well at least very little friction, can spin with one finger easily. There is a large nut in center but from what I have googled this does not have to be removed to change brake shoes. Sprayed some WD40 to help things a bit, and have tapped moderately lightly with hammer but no movement at all. In other vids those models have two threaded holes for bolts to go in and push drum off, but mine does not have those holes. What am I doing wrong? and how do I get the drum off so I can replace shoes? Any help would be much appreciated.

Can you give us some more info.. Year and engine size, model type, 2wd-4wd.

The workshop manuals I've just had a quick look though show the drum as the complete hub which means the centre nut will need to come off.

Welcome to the forum .

Default old trhead, new post

I had the same issue on a 2009 Swift. The problem was that the drums were worn, leaving a lip on the inner edge of the original diameter. Because the rear brakes are self adjusting with no way to back off the adjuster, the diameter of the shoes was larger than the 200mm diameter of the unworn lip on the drum. I ground the heads off the 2 shoe retaining pins on the backing plate with a die grinder, removed the hyd pipe and 2 bolts from the wheel cyl, refitted the wheel and used brute force to twist, turn, pull & yank the drum off. The lower anchor points of the shoes got slightly bent in the process, as expected, but as new shoes were going on that didn't matter.

I then used a small angle grinder to remove the lip to accurately measure the drum, which was 201.2mm diameter. As the wear limit is 202mm the drums went back on - until next time. New retaining pins were fitted.

mine has a rubber bung covering a slot giving access to the adjusting ratchet to release it for just this very reason. Obviously not fitted on your model. The drums do need to be removed with a puller usually as they tend to bind on the hub centre

That would be handy but this little beast has the rear stub axle and backing plate mounted to a 10x12cm approx plate that forms part of the axle assembly which covers the spot where access to the adjuster would be - I just double checked.

The FSM (factory service manual) simply says: remove the nut holding the drum assembly on the stub axle and use a slider (small one in picture) to remove if need be.

mines the same (2wd) but has a cutout right beside the wheel cylinder to get to the adjuster

The ratchet adjuster is about 2-3cm below the wheel cyl and a bit to the front of it. This is a Swift 2009 RS415 2wd. What model do you have? Curious.

I don't know why the pic is so HUGE - sorry. It's the same size I use on other forums.

I managed to get the right (pictured) drum off with a bit of difficulty but had to 'attack' the left one as described above.
