What are "banjo" fittings and bolts?

A banjo fitting is the ring-shaped connector at the end of your brake hose with a hole in the middle. A banjo bolt is a special, hollow bolt that passes through this hole, allowing brake fluid to flow from the master cylinder, through the bolt, and into the brake line (and vice-versa at the caliper).

How do I properly bleed my brakes after installing a new line?

Bleeding brakes removes all air from the system. Start at the caliper furthest from the master cylinder. Have a friend pump the brake lever a few times and hold it, then you open the bleeder valve briefly to release fluid and air, then close it. Repeat this process until no more air bubbles come out. Tapping the brake line can help dislodge stubborn air bubbles.

Do I need new crush washers every time?

Yes, absolutely. Crush washers are single-use items made of soft metal (like copper or aluminum). When you tighten the banjo bolt, they "crush" to create a perfect, high-pressure seal. Once crushed, they will not seal properly again and will likely cause a dangerous brake fluid leak.
