Front Disc Brake Caliper Disassembly and Reassembly: Disassembly

WARNING: This page is about a different car, the 2011 Suzuki SX4. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: If dust or other impurities get into the brake system, they can cause brake failure, which could lead to an accident. Clean the surfaces on and around the caliper with brake fluid before disassembling it.

Remove disc brake piston with air blown into flexible hose joint bolt installation hole.
WARNING: If you place your fingers in front of the piston when you push it out with compressed air, you may hurt your fingers. Do not place your fingers in front of the piston when removing it using compressed air.

NOTE: Using compressed air that is under high pressure can force the disc brake piston quickly out of the cylinder and damage the piston. Use a moderate air pressure to push the piston out of the cylinder slowly. In addition, place a cloth (1) in front of the piston to prevent it from being damaged.
