Up for auction is a CNC machined 6061 aluminum  socket for Hope brake caliper bore caps.  It fits the large cap on the mono M4, The X2, and both caps of the E4 and V4 also the large cap of the RX4 Shimano.  This tool is compact, small enough to push into the bore to remove the cap but the big hex makes it easy to turn when to restart the cap. The hex fits 16mm and 5/8" sockets. 

 Brake is not included, only the tool !!

This is made in the USA by WCM!!!
