Hi, guys just bought Speed triple RS 6 months ago and so far just put 700 miles on it. Lately, rear brake has been making this weird howling noises (not squeak) and I feel the brake grabbed the disc. Upon inspection, I noticed that the caliper had some play, I mean I could move them slightly up and down and side to side. I tightened the two bolts that hold the caliper and they both were tight. Is this normal on the triumph?, thanks guys.
