How do you adjust a rear caliper piston?
To adjust initially, the piston is adjusted outward by turning the nut on the lever or by cranking the lever. This ratchets the caliper piston outward just like using the emergency brake would do. This moves the piston outward taking up that distance between the rotor and the pads.
How does a screw in brake caliper work?
There is a cone behind the piston and it moves with the piston when the foot brake is applied. When the parking brake is operated, the brake lever turns the screw on which it is mounted (it also is an an adjusting screw threaded through an adjusting nut). The nut can’t turn because it’s splined into the cone.
What causes caliper piston to retract?
Square cut seals around the caliper pistons deform when the pistons move, so when pressure is released the seals want to return back to their original shape. This helps retract the pistons slightly,allowing the pads to kick back away from the rotors.
