How to Operate Dragging Brakes?
3 Answers
Poor return of the brake master cylinder. This condition generally results in the phenomenon of multiple wheels "dragging brakes" simultaneously. Blockage in the brake pipeline. This usually occurs on a single wheel, requiring replacement of the pipeline and inspection of the cause of the blockage. Poor return of the brake slave cylinder. Due to possible moisture content in the brake fluid, the piston of the slave cylinder may rust, preventing flexible return. Due to aging and damage of the dust cover on the guide pin, rusting occurs, causing the brake slave cylinder to fail to return in time.
As a car enthusiast, here are the key steps for operating the handbrake when towing: First, turn off the engine to ensure safety. For manual transmissions, shift directly to neutral (N), while for automatic transmissions, refer to the vehicle manual as some models may have a towing mode setting. Then, release the handbrake—either by pressing the release button or pulling the handle loose—to ensure the brake pads don’t rub. If not released, the wheels may lock during towing, potentially damaging the brake discs, chassis, or even the engine. I’ve seen cases where improper towing led to transmission failure. Also, check that tire pressure is normal to avoid skidding. If storing the car long-term, start it periodically to prevent rust. In short, thorough preparation protects your car and saves on repair costs.
I pay attention to safety risks when performing towing brake operations. Releasing the handbrake and shifting to neutral is fundamental. For manual transmission vehicles, shifting to N is straightforward, while automatic transmissions require key adjustment or checking indicator lights to avoid forced towing that could damage internal gears. I once experienced an incident where the tow truck operator didn't release the handbrake, resulting in overheated and deformed brakes, leading to costly repairs. Therefore, before operation, carefully read the vehicle manual to clarify requirements; monitor the vehicle's condition during towing to prevent accidents. Don't overlook small details—safety first to avoid trouble.
