Semi Trailer Brake Chamber
- Applicable Models: Semi-trailers, flatbed trailers, lowbed trailers and box trailers equipped with standard air brake system
- Function: Convert air pressure into mechanical force to actuate trailer braking system
- High-strength Steel Housing: Anti-impact, corrosion resistant, long service life
- Durable Rubber Diaphragm: Good elasticity, oil & water resistance, leak-proof
- Fast Response & Stable Force: Reliable braking force in repeated and emergency braking
- Strict Air Tightness Test: Prevent air leakage and braking failure
Description
This semi-trailer brake chamber is the pneumatic actuator for trailer air brake system. It converts compressed air pressure into mechanical thrust to push the brake slack adjuster and S-cam for braking. Housing made of high-strength steel, fitted with durable rubber diaphragm for stable response under air pressure. Corrosion-resistant, dust and water proof for long service under harsh road and weather conditions. Compact structure with fast brake response, stable braking force during repeated braking. Each brake chamber passes air tightness, pressure endurance and stroke test before delivery. Fixes common faults such as weak braking, air leakage, slow response and diaphragm cracking. Key pneumatic replacement part for semi-trailer brake system maintenance and overhaul.
