Re: How do i push piston in rear caliper back ?

        If it doesn't have two slots on the side, then it must have what looks
like a hole in th middle of it.  There is also a special tool for this.  What I
did was take a 12 or 13 mm bolt and welded a taiwan socket to it.  Worked
excellent to screw the pistons in.
Good Luck,
