How to Release a Locked Trailer Spring Brake?
1 Answers
To release a locked trailer spring brake, you can fully pull out the screw rod to engage the brake. Below is relevant information about spring brakes: 1. Component Parts: A conventional air brake system consists of a brake control mechanism, dual-circuit brake mechanism, brake assembly, air compressor, etc. The brake control mechanism includes components such as the brake pedal, pedal hanger, and manual brake valve. The dual-circuit brake mechanism comprises components like the air reservoir, brake valve, low-pressure alarm, air pressure regulator, brake pipe, directional valve, relay valve, safety valve, and drain valve. 2. Definition: Spring brakes are mostly used in the parking brake systems of medium and large vehicles. The parking brake system of such vehicles normally employs high-tension springs to maintain a constant braking state. When the vehicle needs to move, the driver releases the parking brake by performing an air-filling action, which requires reaching a certain air pressure to overcome the spring tension.
