Re: Changing Rear Brake Rotors

When re-fitting fronts, before you push the pistons back to allow re-assembly, be sure to open the bleed screw first, and drain fluid into a cup or similar.
That way you won't push crap back into the circuit that could stuff up your M/C or ABS passages if you have ABS.
The rears are different in that because of the handbrake mechanism, you can't just push the piston back for it to all go back together.
You will need to wind the piston back with a special tool. When assembled a couple of handbrake lever pulls will automatically reset the proper rotor/pad clearance.
Anyway, probably also a good idea to change to new brake fluid afterwards.
