What happens here

Before installing the caliper, use a C-clamp to compress the caliper piston fully back into its bore. This makes room for the new, thicker brake pads. Be careful not to damage the dust boot. Place the caliper over the new pads and rotor, and insert the slide pins, tightening them securely. If replacing the caliper, ensure the new caliper's bleeder valve is positioned at the top for proper air purging. Install the new caliper, connecting the brake hose with new crush washers on both sides of the banjo bolt, then tighten the banjo bolt. Bleed the brake system to remove any air introduced during the process. Attach a clear hose to the bleeder valve and submerge the other end in a bottle partially filled with brake fluid. Have a helper slowly pump the brake pedal 2-3 times and hold it down. While the pedal is held, open the bleeder valve to allow fluid and air to escape, then quickly close it. Repeat this process until no air bubbles are visible in the hose and the fluid runs clear. Continuously monitor the brake fluid reservoir and top it off as needed to prevent it from running dry, which would introduce more air into the system.

Goal: Install the brake caliper and remove air from the brake lines.

I like to apply a small amount of grease. Get yourself a small C-clamp, compress your piston, and install your caliper. But, now what if you need to replace your caliper? Make sure you have the correct caliper with the bleeder on top so air can exit. You're going to want to put each one of these crush washers on either side of your hose. Disconnect your old caliper. Make sure you remove the crush washer on both sides. Insert your new banjo bolt. Put a crush washer on this side, and install your banjo bolt. But, just bolting this on and adding pads doesn't finish the job. We introduced air into the system, so now we got to bleed them. Get a hose and a bottle. 1 2 3 pump. Crack your bleeder. Close it. Pump. Crack the bleeder. Make sure that it's solid. And don't let your reservoir run dry. Put your wheel
