How to Adjust the Gap of an Electromagnetic Brake?
2 Answers
Loosen the mounting bolts evenly with a hex wrench. Adjust the hollow screw with a wrench and also adjust the air gap at the mounting bolt of the interval until the air gap at all positions meets the standard. Then tighten the mounting bolts with a hex wrench. Use a feeler gauge again to recheck whether the air gap meets the standard.
Adjusting the gap of the electromagnetic brake is indeed a technical task. First, I put on gloves and use a wrench to loosen the fastening nut, locating the adjustment bolt. Then, I measure the original gap with a feeler gauge, usually keeping it between 0.3-0.8 mm. Slowly rotate the adjustment bolt while continuously checking with the feeler gauge. Once adjusted, immediately tighten the lock nut to prevent loosening while driving. Finally, test it by shifting to neutral and spinning the tire—there should be no friction noise, and braking should provide noticeable resistance. The key is controlling the rotation amplitude; adjusting too tight can cause brake overheating, while too loose affects braking performance. It's recommended to use a vernier caliper for precise measurement, as this directly relates to driving safety.
