I bought new master cylinder and brake lines. The master
cylinder is the bus type and has the brake fluid reservoir
built into the top (WRONG!). The Bus Master cylinder has a
larger diameter and requires too much pedal pressure to
stop your car. Use the master cylinder that matches your
brakes!
You always need to look
closley at your brake lines. If they are cracked or you can't
blow through them easily, then replace them. Rubber brake
lines are required in most states because their failure mode
is to plug up rather than leak. The stainless steel brake
lines are more durable, but when they fail, you lose your
brakes!
