Why Brake Line Flaring is Important
Brake line flaring is a critical step in brake repair because it ensures a secure connection between the brake line and the brake caliper or wheel cylinder. A properly flared brake line connection is essential for several reasons:
- Safety: A secure brake line connection is critical for safe braking performance. A loose or improperly flared connection can lead to brake failure, which can result in accidents and injuries.
- Reliability: A properly flared brake line connection ensures that the brake system functions reliably, even under heavy braking conditions.
- Prevents Leaks: A flared brake line connection prevents brake fluid leaks, which can cause damage to the brake system and lead to costly repairs.
Types of Brake Line Flare Tools
There are several types of brake line flare tools available, each with its own unique features and benefits. The most common types of flare tools are:
Manual Flare Tools
Manual flare tools are the most common type of flare tool and are used for most brake line repairs. They consist of a handle and a flare forming die that is used to shape the brake line into a flare.
Hydraulic Flare Tools
Hydraulic flare tools use hydraulic pressure to form the flare, making them faster and easier to use than manual flare tools. They are typically used in high-volume brake repair shops.
Pneumatic Flare Tools
Pneumatic flare tools use compressed air to form the flare, making them fast and efficient. They are typically used in heavy-duty brake repair applications.

Step 1: Prepare the Brake Line
Before you start flaring the brake line, make sure it’s clean and free of debris. Use a brake line cleaning brush to remove any dirt or corrosion from the inside of the brake line.
Measuring the Brake Line
Measure the brake line to ensure it’s the correct length for the repair. Use a brake line measuring tool to measure the length of the brake line.
Step 2: Cut the Brake Line
Use a brake line cutting tool to cut the brake line to the correct length. Make sure to cut the brake line at a 45-degree angle to ensure a proper flare.
Deburring the Brake Line
Use a brake line deburring tool to remove any burrs or sharp edges from the cut end of the brake line.
Step 3: Form the Flare
Place the brake line into the flare tool and tighten the die to form the flare. Make sure to follow the manufacturer’s instructions for the correct flare size and type.
Forming the Flare
Use the flare tool to form the flare, making sure to apply even pressure to the die. Check the flare to ensure it’s properly formed and free of defects. (See Also: How Does a Emergency Brake Work? Unveiled)
