The disc brake piston may not be retracting properly due to issues such as a seized piston, worn out seals, or air in the brake system. These issues can prevent the piston from moving back into its original position after braking, leading to brake drag and reduced braking performance.
The teves caliper is a single piston disc brake caliper and the akebono caliper is a dual piston disc brake caliper. The teves caliper is a single piston disc brake caliper and the akebono caliper is a dual piston disc brake caliper.
The piston retracts by turning it back in. You will need a Disc Brake Pad Spreader (Part Number: 648412) and a Disc Brake Piston Tool (Part Number: 648410) found at Advance Auto Parts. The Brake Piston Tool looks like a Rubik cube. Simply line up the knobs into the piston slots and place the disc brake pad spreader between the caliper and brake piston tool. Apply slight pressure on the piston via the pad spreader and turn the brake piston tool with a screw driver while continuing to apply pressure on the brake piston tool. From what I have read they could retracted by turning either clockwise or counterclockwise.
A disc brake piston tool is the best tool to use for removing brake pads on a car. It helps compress the piston back into the caliper, making it easier to install new brake pads.

Turn the piston clockwise and it scews itself in...
First the driver puts pressure in the foot brake, which then pushes a small piston, the piston then exerts pressure in the brake fluid. Then the increased pressure is transmitted through the fluid in the brake lines to a larger piston within the wheels of the car. Each piston pushes in a brake pad which the rubs against the brake disc, and the wheels motion is slowed down by the force of friction.
The best bicycle disc brake tool for maintaining and adjusting disc brakes on a bike is a disc brake caliper alignment tool. This tool helps ensure that the brake calipers are properly aligned with the rotor, which is essential for optimal braking performance.
Screw the piston puck in clockwise. There is a tool for this (KN or KY) that is a box with little dowel pins to fit the slots in the caliper piston. What you are actually doing is resetting the parking brake. As the pads wear and you set the parking brake, each actuation of the parking brake foot lever ratchets the piston outward to componsate for pad wear.
Drum brake? Broken return spring? Bad self-adjuster? Parking brake not adjusted properly? Disc Brake? Frozen caliper? Parking brake not adjusted properly?

To properly install a Shimano disc brake spacer on your bike, follow these steps: Remove the wheel from the bike. Place the spacer between the brake pads. Reinstall the wheel and make sure it is securely in place. Test the brake to ensure it is functioning properly. Make sure to refer to the specific instructions provided by Shimano for your particular disc brake model.
When you are changing disc brake pads, you should use one of the old pads and a large clamp to compress the piston immediately after removing the caliper. This helps to prevent air from entering the brake lines.Use caution when positioning the clamp so that it does not put any pressure on the brake hose, bleeder valve, or anything other than the piston housing.If the piston is difficult to compress, you may have a frozen caliper and/or a leaky brake hose.
