Hi Lee, those look the same as the one's on my 88 CE , there are 2 bolts that screw into hollow bolts at the back side of the caliper, 15 &17 mm wrenches if I remember correctly.Hold the hollow bolt and remove the inner bolt.The 124 CD has them listed as 'fixed' calipers but they are floating calipers.The calipers in the DIY section are different than what you have. Good luck.
