I bought this ATV a week ago from my friend who had it since 1997. He barely rode it and it sat in his garage for 15 years. Only had 1500 miles on it. Looks and runs like it’s brand new. Brought it home and changed the oil and put a new battery in it and it started right up. The only issue was there was no brake fluid in the handlebar master cylinder. And there was no pressure in the foot brake or the handle Brake. I added brake fluid but still did not build pressure. I figured I would bleed the brakes later. I rode the four wheeler a couple of times and no problems. But today I was riding and I heard a weird noise coming from the front right tire. And the ATV started pulling hard to the right. Luckily I was pulling into the driveway and I parked it. When I got off the ATV there was smoke coming from the inside of the tire caliper area. I got a flashlight and it looks like it’s coming from the bleeder valve hole. Please any suggestions for I am new to ATVs
