Understanding the causes of car brake lockup and finding ways to fix them is essential for drivers.
Car brake lock is one of the common problems that can be dangerous for drivers when driving on the road. What causes brake lock and how to handle it?
Brake pad wear
Excessive brake pad wear is one of the causes of car brake lock. Excessive brake pad wear leads to worn brake discs. This causes the brake piston to be pushed beyond its limit, unable to return to its original position, causing the brake lock.
This is mainly due to the user not checking for regular maintenance. Therefore, when encountering the above situation, the car owner can remove the wheel, remove the brake assembly, use a screwdriver to push the piston back to its original position, then bring it to the repair center.

Brake master cylinder is rusted.
When braking, the brake piston will exert a large force on the brake caliper, helping the brake to work effectively. However, if rusted, the brake caliper cannot return to its original position, leading to brake lock.
In this case, the owner can remove the battery to clean and lubricate it. In addition, the brake piston, brake pads and brake discs should also be checked. If the battery and rubber gasket are damaged, these parts need to be replaced.
Deformed brake disc
This is also one of the common causes of car brake lock. Due to external impact, the brake disc is deformed, does not rotate evenly but has a wobble phenomenon. At that time, the brake pads are always in a state of pressing tightly against the brake disc surface, leading to brake lock.
For this reason, the simplest temporary fix is to remove the stuck brake pads until they are fully repaired.

Many inexperienced mechanics adjust the brake pedal amplitude too small, causing the brake pads to always press against the drum or disc. When the driver steps on the brake, it will cause the brakes to lock up instantly.
The best way to handle this is to choose a reputable garage to thoroughly handle the problem. If left for a long time, it will lead to wear and tear on the brake pads and discs.
Brake pads swell due to water absorption
After driving in the rain or washing the car, water gets into the brake system, causing the brake pads to expand. This reduces the braking performance. The wet brake pads are pressed against the brake drum, causing the brakes to lock.
To fix this, the car owner must dry the brake pads. If you stop the car immediately after driving through a flooded road, do not pull the handbrake immediately. The best way to handle this is to shift into reverse for a manual transmission car (or P for an automatic transmission car) and then back to forward until the brake releases automatically.
In addition, there are some other causes that can cause brake lock related to technical problems such as broken brake pad return springs, broken brake master cylinder. In these cases, you need to take your car to a reputable garage for inspection and repair.
