The correct sequence for bleeding brake lines on most front-wheel drive vehicles typically follows a pattern that ensures any trapped air is removed efficiently from the brake system. The chosen sequence starts from the furthest brake line from the master cylinder and moves to the closest. This approach helps to maintain pressure and ensures that any air bubbles are released in the proper order.

In this case, bleeding begins with the rear right (RR) brake, followed by the rear left (LR), then moves to the front right (RF), and finally the front left (LF). This sequence helps in effectively clearing any air from the brake lines. Following this specific order is significant for achieving proper brake performance and maintaining safety.

It's important to note that other sequences might start with different brakes, potentially leading to air remaining in the lines, which can compromise brake efficiency. Each vehicle may have specific recommendations, but the sequence chosen aligns with the standard practice for most vehicles, especially those set up with a diagonal brake system.
