Is any special tips/processes when replacing all the brake lines?

Replacement of the brake lines only requires normal bleeding procedures - it just takes a long time and lots of brake fluid to purge all air from the system! As a rule, the brake circuits on most vehicles with anti-lock brakes can be bled in the usual manner, provided no air has gotten into the ABS modulator assembly. If the only components you replaced were downstream of the modulator (calipers, wheel cylinders, brake hoses or lines), chances are normal bleeding procedures will clear the lines of any unwanted air. Brakes can be bled manually, with a power bleeder, injector tool or vacuum bleeder. It does not make any difference which method you use as long as all the lines and components are flushed with enough fluid to remove any trapped air bubbles or air pockets. The most common bleeding procedure is to bleed the brake furthest from the master cylinder first, then bleed the other brake that shares the same hydraulic circuit (which may be the other rear brake on a rear-wheel drive car or truck, or the opposite front brake on a front-wheel drive car or minivan). After these have been bled, you then bleed the other brake circuit starting with the furthest brake from the master cylinder. Always refer to the vehicle manufacturer's recommended bleeding sequence as this may vary from one application to another depending on how the system is configured.
