CM-041125 Types of Brake Lines & Flares

Description

Brake lines are vital to vehicle safety, made up of durable tubing, fittings, and connectors designed to withstand high pressure. Most modern vehicles use steel lines for strength, while copper offers easier bending. Fittings—typically brass or stainless steel—ensure a tight, leak-free seal, and proper flaring is key to maintaining hydraulic pressure. There are two main flare types: double flares and bubble flares. Double flares, common in newer vehicles, use a 45° angle for a strong, high-pressure seal. Bubble flares, often found in older models, create a rounded end for specific fittings. Choosing the correct type depends on the vehicle’s design—always verify using the service manual or by inspecting the existing line. Mastering proper flaring techniques with quality tools ensures safety, reliability, and professional results for every brake line service.
