Hello everybody.... I recently purchased a 1995 YZF600. It has about 22000 miles on it. Tread is good on the tires and brake fluid is topped up. Recently, I've noticed whenever I use the front brakes, the front end bobs up and down a bit (I don't recall feeling this when I took it out the first few times). It feels like the brakes are grabbing every revolution. My little pea brain is telling me that there is something wrong with the front discs. However, I can't see any obvious problems. I'll be taking it to the shop soon, unless I'm missing something that someone here can point out. Thanks.
