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.
