Some BMW 850i owners report experiencing brake jamming issues after short drives when the engine is hot, which may be attributed to brake calipers seizing. This problem can result in the brakes binding and overheating, even after attempts to clean the calipers, bleed the brakes, and replace broken seals. Symptoms of this issue often include unusually high engine revs with slow acceleration, leading to difficulties in driving at low speeds. To mitigate these concerns, owners are advised to check for signs of caliper seizing and monitor the brake system for binding or overheating, especially in hot conditions. If the issue persists, consulting a professional mechanic or BMW specialist is recommended to diagnose and repair any underlying problems. Regular maintenance and inspections of the brake system are essential for ensuring safety and optimal performance in the BMW 850i.
