the bolts that hold the calipoer to the caliper bracket? just hold the caliper slide with a wrench or a vise grip and loosen the bolt with a wrench or a socket.
In the last couple weeks I have:
-replaced battery tray
-installed Optima battery
-shrink tube wrapped battery cables to cover exposed copper
-installed new IAC
-changed oil and filter
-installed hub bearing assembly
I did notice that I will be needing new brake pads soon also
