What causes brake drum overheating?
Dec 05,2024
The main reasons for overheating of the car brake drum are:
1. The gap between the left and right brake drums and the brake pads is inconsistent;
2. The air pressure of the left and right tires is inconsistent;
3. The left and right brake lines are blocked, resulting in different hydraulic or air pressure on both sides;
4. The brake shoe return spring is broken or too soft;
5. The slave cylinder piston is Mika, and the return stroke is slow;
6. (Oil brake) The brake fluid returns slowly;
7. (Air brake) The brake camshaft does not return;
8. Corrosion of the support pin;
9. The brake drum is out of round;
10. The wheel hub bearing is adjusted too tight;
11. Insufficient or excessive gear oil, and the gear oil viscosity is too low.
[Warm Tips] Please try to drive in places with good road conditions, avoid sudden braking and frequent braking, add the specified type of gear oil, and pay attention to the amount of filling. The bearing clearance needs to be adjusted at the service station.
Treatment method: Please do not pour water on the brake drum to cool it down. The brake drum cools suddenly and shrinks unevenly, which is easy to cause rupture. When the brake drum temperature drops, drive the vehicle slowly to a service station for inspection.
