In winter, brake pads can suddenly seize from ice. An expert from Behind the Wheel, Alexey Revin, shares practical steps to free them without damaging the system. The goal is to restore a safe braking response while avoiding harm to the components themselves.
One item to keep handy for winter trips is a length of hose. It can be stored in the trunk for ready access. When needed, the hose is positioned to channel warmth toward the brake area, helping to melt ice and restore release. This method is designed to work with typical braking systems, though results can vary depending on the vehicle and conditions.
To use this technique, the hose is routed to the exhaust area and the engine is started. The other end of the hose is directed toward the brake mechanism to introduce heat. If the vehicle has alloy wheels with spokes, the hose can be threaded carefully between the spokes. In vehicles with outriggers, wheel removal may be necessary to access the brake components more effectively.
For drum brakes that have frozen, a gentle tap on the drum using a wooden block can help break the bond. Care should be taken to avoid hard blows that might damage the drum or internal mechanisms. This approach does not guarantee success in every situation, but it can reduce the resistance caused by ice buildup.
Another straightforward method some drivers rely on is applying heat by boiling water and carefully pouring it onto the affected brake areas. After addressing the ice, it is important to dry the wheels completely. A practical way to do this is to drive for a period with the handbrake lightly engaged, which allows the pads and rotors to warm and moisture to evaporate. This technique should be performed with caution and awareness of road conditions and overall braking safety.
