no u don't have to bleed the calipers, but when u push the piston back in the bore open the bleeder valve so you don't push all that dirty brake fluid back up into the master clyinder, close the bleeder install pads and rotors pump the brakes up now take the cap off the master clyinder fill it up now open up both bleed screws don't touch the brake pedel- soon you will see fluid comin out with no bubbles close them then fill master put the cap on! with the cap off you have 14psi pushin the fluid out, it's called self bleeding////// yes repack the bearings
