Parking Brake Failure: Causes and Effective Solutions

Anh Tuan, owner of a Dongfeng B180 truck operating on the Hanoi – Bac Ninh route, once had a near-miss accident due to a faulty parking brake. While parked on the Nhật Tân Bridge to deliver goods, he forgot to engage the parking brake. Luckily, he noticed the truck rolling and reacted in time. Since then, he always reminds himself and fellow drivers about the importance of regularly checking the parking brake.

So, what does “parking brake failure” mean? What causes this issue, and how can it be fixed? Let’s explore this with XE TẢI HÀ NỘI!

What is a Parking Brake? Its Importance

The parking brake, also known as the emergency brake, is a secondary braking system that supplements the main brakes, keeping the vehicle stationary when parked on slopes or uneven terrain. This system is especially crucial for trucks, which often carry heavy loads and navigate various terrains.

Causes of Parking Brake Failure

Several factors can contribute to parking brake failure, including:

• Stretched or Broken Parking Brake Cable: This is the most common cause. Cables can stretch due to prolonged use, friction, or rust.
• Worn Parking Brake Shoes: Worn brake shoes also reduce braking effectiveness.
• Faulty Parking Brake Adjuster: This component regulates the tension of the parking brake cable. If it malfunctions, the parking brake won’t work efficiently.
• Seized Brake Shoes: Dirt, grime, and rust can cause brake shoes to seize, leading to parking brake failure.

Signs of Parking Brake Failure

Early detection of parking brake issues allows for proactive solutions, preventing potential accidents. Here are some common signs:

• The parking brake lever feels loose and doesn’t provide a secure feeling when engaged.
• The vehicle rolls even when the parking brake is engaged in the “P” or “1” position on a slope.
• Unusual noises occur when engaging or releasing the parking brake.

How to Fix Parking Brake Failure

Depending on the cause, you can apply the following solutions:

• Adjust the Parking Brake Cable: If the cable is stretched, you can adjust it yourself or take your vehicle to a garage for assistance.
• Replace the Parking Brake Shoes: Worn brake shoes need replacement to ensure effective braking.
• Repair or Replace the Parking Brake Adjuster.
• Clean the Brake Shoes: You can clean them yourself or have a garage do it.

Note:

If you lack experience, it’s recommended to take your vehicle to a reputable garage for inspection and repair by qualified technicians. Attempting repairs without sufficient knowledge can cause further damage to the braking system.
