Hey everyone! I'm still working on this Troy-Bilt Bronco 13aj609g766. I got it free a while back and I've made some posts on it. It's been running pretty good after replacing belts, oil gasket, gapping valves, etc. I had some drive belt troubles where it wasn't pulling hills but I think I sorted it out. I inspected the drive and transaxle and variable speed pulleys and they all were pretty shiny and smooth where the belt goes, so I think they were glazed. I could even see the reflection of the ground in one. I sanded them with coarse sand paper and put it back together and it went up the hills again no problem. Only other variable that could affect my results from before and after the sanding is that when I noticed trouble the first time I had been running the machine for a couple hours and after the fix I tested it after it had been on for only about 20 minutes, so heat might come into play, but I think 20 minutes of continuous driving is enough to warm everything up.
Anyway, the brakes have never worked right and it's almost killed me a couple times now so I want to sort it out. When I got it at first the brake rods that push the pad into the disk (mounted on the gearbox) were siezed. I unsiezed them so they could actually push the brake pad on and cause friction. But I can't adjust it right. If I tighten the adjustment nut about 1/8 turn too much the mower constantly rides/grinds the brakes and locks up in reverse, but if it's much looser the brakes are too weak to hold the tractor still on inclines. Additionally the parking brake mechanism won't stay engaged for more than a few seconds, but I think that's a different issue. Does anyone have experience with this issue? Is my linkage not pulling enough or is the tiny brake pad junk?
