Can you replace a bleeder screw without replacing the whole caliber?

In most cases, yes, you can replace a bleeder screw without replacing the entire caliper. Bleeder screws are typically much less expensive than calipers, and replacing them is a relatively simple procedure that can be completed in just a few minutes.

Here are the steps on how to replace a bleeder screw:

1. Gather the necessary tools and materials. You will need a new bleeder screw, a wrench, and some brake fluid.

2. Park your car on a level surface and turn off the engine.

3. Locate the bleeder screw on the caliper. It is typically located at the top of the caliper, near the brake line.

4. Place a rag under the bleeder screw to catch any brake fluid that may spill.

5. Use the wrench to loosen the bleeder screw. Be careful not to over-tighten the bleeder screw, as this can damage the caliper.

6. Once the bleeder screw is loose, remove it from the caliper.

7. Install the new bleeder screw into the caliper. Hand-tighten the bleeder screw until it is snug.

8. Use the wrench to tighten the bleeder screw until it is snug. Do not over-tighten the bleeder screw.

9. Add brake fluid to the master cylinder reservoir.

10. Press the brake pedal several times until the pedal feels firm.

Test the brakes to make sure they are working properly. If the brakes are not working properly, you may need to have the brake system inspected by a qualified mechanic.
