Left brake has been squeaking for a while after I used it (use the brake and it would squeak for a few turns of the tire) so I took it apart to check. The pad and shoes are worn with a big chamfer on the outward side. Worn enough that there is a burr rolled into the metal part of the shoe. Top spring anchor has been dragging too. Like the brake drum is too far in. a few years back I replace the hub on the right side and adjusted the bearing play. It took a lot of shims to get the bearing set right. Did I screw it up and pull the axles towards the right and cause interference on the left brake drum? Manual says bearing play can be adjusted on either side. That’s why I’m thinking I shifted the whole works over to the right. Is this possibel or is something else wrong? thanks
