How to Handle Air Leakage in Brake Caliper in Emergency?

Disconnect the brake pipe joint of the brake caliper. Find a thinner plastic bag, tear off a piece and roll it into a ball, then insert it into the air source input port of the brake caliper. Reinstall the brake pipe back to the brake caliper as it was. Below is some relevant information about brake calipers: 1. Classification: Automotive brakes are divided into air brakes and hydraulic oil brakes. Air brakes consist of an air compressor (commonly known as an air pump), at least two air reservoirs, one brake master cylinder, one quick-release valve for the front wheels, and one relay valve for the rear wheels. Hydraulic brakes are composed of a brake master cylinder (hydraulic brake pump) and a brake fluid reservoir. 2. Principle: When the brake is pressed, the oil outlet opens and the oil inlet closes. Under the pressure of the pump piston, the brake fluid is squeezed out of the pipe and flows to each brake caliper to perform the braking function. When the brake pedal is released, the oil outlet in the brake master cylinder closes and the oil inlet opens, allowing the brake fluid to flow back from each brake caliper to the brake master cylinder, returning to the original state.
