Hello, The caps on my LR caliper were gone and one of the boots was chewed away. NAPA and Carlson both offered replacement boots with NO CAPS. That's silly. The fine fellows at Tasca had a Volvo kit (p/n 30683788) for >$14 + s+h. I don't know if it was for 1 or 2 calipers. I finally found a per wheel kit from Wagner (p/n H8217) with caps, online for $4.81 + $2.02 s+h. My pins were dry and I'd recommend inspecting them. Removing the pin with a 7mm allen is easy; as is replacing a boot-they simply pull through a hole in the caliper's frame. You can service/regrease the guide pins one at a time without disturbing anything or risking downtime. Kira
