“I was bleeding the brakes on a 2008 Honda CR-V when I noticed a bolt on the rear caliper that was loose to the point it spun when I accidentally touched it with my finger.”source ↗

“Honda service manual says do not loosen that special bolt but the previous owner had a shop service the rear caliper and it may have been loose since then. Should I get this replaced or have a shop check it?”source ↗
