Which precaution applies when retracting a screw type rear caliper piston?

  • A.The piston must be wound in, not pressed
  • B.The piston must be pressed in with a clamp, which is the same procedure used for a front caliper piston
  • C.The caliper must be heated
  • D.The bleed screw must be opened first, which allows the fluid to escape rather than being forced back to the reservoir

Answer: A

Pressing a screw type piston destroys the adjuster mechanism inside, so a winding tool must be used. Opening the bleed screw is good practice for any piston to avoid forcing dirty fluid back through the modulator, which makes the last option partly sound. The order in which the effects act is what decides the outcome, so it is worth establishing first. Naming what changes and what stays the same is the reliable route through questions of this shape. Working one numerical case through both cases side by side fixes the distinction better than any rule of thumb.
