Parked, got out and there was a puddle of brake fluid forming on my right rear wheel. I bend down and take a look. I find the brake piston staring back at me over the top of the rotor because the slide pin bolt was absent and no longer keeping the caliper in place.
Got back home, and saw that I was very lucky that the piston had not gotten lost. It was just hanging on to the caliper by the dust boot and somehow did not get scuffed up by the rotor.
So a quick $18 later at RockAuto.com and I have a new set of seals and guide pins with bolts in the mail.
Funny thing is, it has been a good year and a half or more since I had last taken the caliper off to change pads.
I feel like I should safety wire these things in place...
