Remove the two caliper pins on the brake pump and apply grease, or replace all non-rubber caliper pins with rubber ones. Below is some relevant information about calipers: 1. Introduction: A caliper is a tool used to measure length, divided into non-dial calipers and dial calipers. External calipers are used to measure the outer diameter of a cylinder or the length of an object, while internal calipers are used to measure the inner diameter of a cylindrical hole or the width of a slot. 2. How to Use a Caliper: To take measurements with an external caliper on a steel ruler, place one measuring surface of the caliper against the end of the ruler and align the other measuring surface with the desired measurement mark, ensuring the line connecting the two surfaces is parallel to the ruler. The method for using an internal caliper is similar, except that the end of the ruler must rest against an auxiliary plane, and one foot of the internal caliper must also rest against this plane.

I recently encountered a clicking sound from the brake calipers, like a small hammer tapping on a drum. This issue usually stems from the brake pads wearing down to their limit, where an indicator rubs against the rotor to signal replacement. If ignored, the brake disc could suffer severe damage, leading to repair costs multiplying several times. It's advisable to immediately drive to a professional repair shop to check the brake pad thickness. If they're thin, replacing them will restore quiet operation. Don't forget to regularly monitor brake condition during maintenance to prevent such troubles from recurring. Safe driving is paramount—don't let minor issues escalate into accident hazards.

When the brake caliper makes a clicking sound, I get particularly worried because it could indicate an issue with the braking system, such as stuck or loose guide pins. The last time I noticed this, I went for repairs promptly, and the technician told me the brake pads were nearly worn out, which caused the knocking. They simply replaced them with new ones, and the problem was resolved. If ignored, braking efficiency could decline during emergencies, posing significant risks. Remember, it's best not to tinker with it yourself, especially when it involves braking components. Finding a reliable shop that uses proper tools for the job is the safest approach. Regular vehicle health checks can help reduce such unexpected failures.

The clattering sound from the caliper is often the brake pad wear indicator at work, reminding you it's time for a replacement. It could also be due to rusted guide pins getting stuck, causing friction between the pads and rotors. Have a friend or mechanic check the pad thickness and guide pin mobility with tools as soon as possible. Don't ignore such minor signs, as they may lead to brake failure or costly repairs. Addressing it promptly can restore your car's smooth operation.
