2010 Rancher 420 Rear Brakes

I just purchased a 2010 Rancher 420 4x4 (foot shift, manual 4x4).

When I went and looked at the quad it was in pretty good shape, but the rear brakes didn't work (parking brake and foot pedal were soft with no braking whatsoever). I knew this was probably an easy fix so I purchased the quad anyways.

I tore apart the rear brakes and everything was pretty normal. No mud or water inside the drum, just lots of brake dust. I assumed it just needed new shoes so I went about my business. Went ahead and replace all the seals, shoes, washers, etc. for what I would call an almost total rebuild. I even replaced the wing nuts, cams, and springs at the rear brake cable. Cleaned out the brake lever cam and greased everything up. Lined up the cam with the punch marks and everything seemed good to go.

Yesterday I finally put the tires back on and wanted check the brakes and make final adjustment before a ride.

I had to adjust the wing nuts at least 3/4 of the way to get any feel in the brake lever and pedal, and it still doesn't stop like I think it should. The only thing I didn't change out was the brake cables and the actual drum. From what I could tell the quad has decently low miles (original tires, appeared to be the first time anyone had opened the drum). The brake arm moves freely and returns nicely (spring is stiff). Both the pedal and lever return nicely.

I didn't check the drum specs when I had it apart (assumed it was within spec).

1) Do you think the drum could be out of spec? The old brake shoes didn't even appear seriously warn but from forums and youtube videos, that might not always be the case. I haven't ever done a brake job on a quad, just cars many times (the shoes on cars can be metal on metal and severely warn before needing replacement).

2) Could it be a cable issue? I dont think so because both cables seem to be affected the same.

Just looking for some advice before I order a new drum and bust it all open again.

very well could be a worn brake drum.

Yeah that's what I'm thinking, but would a drum not last the life of a few pairs of shoes? I mean, it's not like it was dragging or rubbing or anything.

depends ?. how was the brakes used ?, how hard was the PO owner on them ?. was the atv taken through gritty stuff a lot ?. are you 100% sure you installed the brake cam right ?. it's best to measure the drum, and see how worn it is compared to service limit specs ?. :-).

what you can do is ( just a temp fix ) , rotate the brake cam back a couple splines, install, then this will give you less travel on the brake shoes before they engage the brake drum.

Yep, rotate the cam back a couple of teeth. It will give you more adjustment on the wingnuts and engage the pads quicker.

Back brakes on Hondas kinda suck. The good news is, if you have it in 4wd, and lock up the front brakes, it's gonna lock up your rear wheels too since the final shaft that runs front and rear end is the same shaft.

Is the cam not keyed? I lined up the punch marks, and just assumed it would only go on one way. If I can do that, I definitely think it would help my cause.

Nope. You just pull the lever off, move it back a couple of teeth, and tap it back on.

couple teeth, no more, or you won't be able to get the wing nuts back on the cable. MAKE SURE TO PULL THE CABLES BACK BY HAND TO REMOVE THE SLACK OUT, THEN EYE-BALL THE DISTANCE ON HOW FAR YOU CAN MOVE THE LEVER BACK. you can use the punch marks as a reference point.
