Hi, Its a pretty straight foreward procedure. Il just paste the honda manual directions here The piston just pushes straight in like front calipers.
Remove the brake caliper bracket mounting bolts and remove the caliper assembly () from the knuckle. To prevent damage to the caliper assembly or brake hose, use a short piece of wire to hang the caliper assembly from the undercarriage. Do not twist the brake hose with force.
Remove the 6 mm brake disc/drum retaining screw
Screw two 8 x 1.25 mm bolts into the brake disc/drum to push it away from the hub. Turn each bolt 90 degrees at a time to prevent the brake disc from binding.
Remove the brake disc/drum from the hub.
Install the brake disc/drum in the reverse order of removal, and note these items:
Before installing the wheel, clean the mating surface of the brake disc/drum and the inside of the wheel.
Before installing the wheels, clean the mating surface of the brake disc and the inside of the wheel.
Ok, ill tell you how I do it.
Remove the lower 12mm bolt from the caliper, rotate the caliper up and slide it off the caliper upper pin
remove both 17mm bolts that hold the caliper bracket to the knuckle.
Remove the 2 number 3 philips screws from the rotors, you may need an impact driver, for sure use a large #3 plillips driver
Pull off the rotor.
Compress the pistor in the caliper with a large channel lock pliers.
Thats it just reverse procedure to reassemble.
I will be on all day if you get in trouble.....
