Well I feel like a dumb ass. Just picked up a 312-8 last week. Mowed the yard for the 1st time and everything was great! Hopped on it yesterday to move the tractor around my house from my shed to the garage. The clutch was making a squealing noise and something wasn't right. All of the sudden smoke started coming up from under the seat and I smelled burning. Shut the tractor down. Looked under the seat, smoke was coming from the wheel in the picture. Drove it around to the front, smoking again. Looked in the manual, found out this was the drum brake. Yep my dumb as had the parking break ON! Full disclosure this was only the 2nd time I was on the tractor but that's no excuse. The dash board lights don't work but I probably wouldn't have seen them anyways. My question is, what kinda damage was done. The brakes still work, but you have to press the pedal to the floor and they feel kinda weak. Haven't tried them yet on a hill. Hopefully I didn't ruin the poor thing. Leave it up to me, tractor's been around for 30 years. I get it for a week and try to burn the brakes out of it. I came across basically a brake pad (drum) on ebay (see pic). But it says you basically just use silicon glue to install? Has anyone done this before? Could I adjust the brake to make it tighter? Would I need a new brake drum?
