What Are Parking Brake Shoes? Symptoms, Replacement Cost & When to Replace Them

What Are Parking Brake Shoes?

Parking brake shoes are small brake shoes located inside the rear brake rotor or brake drum that help keep your vehicle stationary when the parking brake is engaged.

Also known as emergency brake shoes, handbrake shoes, or e-brake shoes, they are separate from the primary braking system and are used only when the parking brake is applied.

When the parking brake is activated, the shoes press against a drum surface to create friction and prevent the vehicle from rolling.

How Do Parking Brake Shoes Work?

Parking brake shoes work by pressing against a drum surface when the parking brake is engaged. This creates friction that helps keep the vehicle from moving while parked.

Unlike the primary braking system, parking brake shoes are used only when the parking brake or emergency brake is activated. Their purpose is to hold the vehicle in place rather than slow it down while driving.

When should you replace parking brake shoes?

To ensure your vehicle stays parked safely, it is essential to replace the parking brake shoes when they become worn or damaged. The friction material on these components will wear down gradually over time and can compromise their ability to keep your car in place. Additionally, rust, corrosion, and other factors may cause damage to the parking brake shoes that must be addressed as soon as possible.

If you're noticing the following symptoms, it may be time to replace your parking brake shoes:

Reduced efficiency: If your parking brake is not providing the same level of stability that it once did, then this may suggest that its shoes are worn and require replacement.

Noise: If your parking brake shoes have been worn, an audible grinding or scraping noise may be produced when the brake is engaged.

Vibration: If you experience a pulsation or vibration when applying the parking brake, it could be indicative of warped shoes or an uneven wear pattern.

Visible Damage: If the parking brake shoes are visible signs of wear and tear or show any kind of cracks, breakage, it's time to replace them instantly.

To guarantee the proper function of your parking brake system, it is advised that you have it inspected by a qualified mechanic on a regular basis. They can identify any worn or damaged parts and make necessary replacements to ensure everything works properly.

Parking Brake Shoes vs Brake Shoes

Although they look similar, parking brake shoes and brake shoes serve different purposes.

Parking brake shoes are used only when the parking brake or emergency brake is engaged. Their primary job is to keep the vehicle from rolling when parked.

Standard brake shoes are part of the service braking system on drum brake vehicles and are used every time the brake pedal is pressed.

How much does it cost to replace parking brake shoes?

Parking brake shoe replacement typically costs between $150 and $500 depending on the vehicle and labor required.

Average Cost Breakdown

Parts: $30 - $150

Labor: $120 - $350

Total Average Cost: $150 - $500

Luxury vehicles and vehicles with complex rear brake assemblies may have higher replacement costs.

Can You Drive With Worn Parking Brake Shoes?

Yes, in most cases the vehicle will still drive normally because parking brake shoes are separate from the primary braking system.

However, the parking brake may not hold the vehicle securely when parked. This increases the risk of vehicle movement, especially on hills or inclined surfaces.

For safety reasons, worn parking brake shoes should be replaced as soon as possible.

How Long Do Parking Brake Shoes Last?

Parking brake shoes often last between 50,000 and 100,000 miles because they are used less frequently than regular brake components.

Their lifespan depends on driving habits, vehicle design, and how often the parking brake is used. Vehicles that are frequently parked on steep inclines may experience faster wear.

What happens if you do not replace the parking brake shoes?

Driving with worn or damaged parking brake shoes can lead to several problems, including:

Rolling Away Risk: As the brake pads of your vehicle's shoes wear down, they become less efficient in restraining it when parked. Sadly, this can lead to an increased risk of rolling away and causing a painful accident.

Damage to other components: Not only can a ruined or worn parking brake shoe cause pricey repairs, but it may also jeopardize the safety of your vehicle. It could damage other components of the parking brake system like a rotor or drum, costing you even more money and putting yourself in a dangerous position.

Increased Repair Costs: When your parking brake shoes become worn or damaged and you continue to use them, expensive repairs could ensue as the damage builds up. Avoid excessive repair costs by taking care of any wear-and-tear issues in a timely manner.

Safety Hazard: A malfunctioning parking brake poses a possible risk of danger, especially when you rely on it to keep your car stationary while parked on an incline or hill.

To conclude, the significance of replacing worn or damaged parking brake shoes cannot be overstated. A faulty parking brake system can compromise safety and efficiency, as well as result in greater repair costs and potentially cause harm to other parts. Therefore, it is essential to get your parking brakes checked regularly and replace any defective components immediately for ultimate protection.
