There is probably air in your brake lines. Or you might have a bad master cylinder.
I believe they are 3/16"
Why would you want to replace all the brake lines? You can flush the entire system and install fresh DOT3 brake fluid. I can see no reason to replace all the brake lines. Why are you doing this? Unless your brake lines are rotted out or someone has cut them... there is no reason to replace all four lines.
In the master cylinder. The same place it's located in a 1998 Buick or any other other car for that matter. I imagine you're asking where the brake fluid master cylinder is because that's where all brake fluid is stored until it's pushed down the brake lines (which, by the way are also filled with brake fluid all the time). What you're looking for is the power brake vacuum device is is on the firewall between the engine and interior on the front of the car. It's usually on the driver's side.
Loosen the power steering lines at the lowest point and drain into a bucket. Remove the 98 LeSabre pump belt, then remove the lines. Unbolt and remove the pump, then bolt in the new one. Connect the lines and belt before filling the pump with new fluids.
Disconnect electrical connection Remove and cover brake lines Remove mounting bolts Pull Master cylinder off power booster Install in reverse order, but remember to BENCH BLEED master cylinder prior to installing

The master cylinder can be easily replaced with a new unit, by disconnecting the brake lines, capping off the brake lines, detaching the old master cylinder by unscrewing two bolts.You must bench bleed the new unit before installing. Then reverse the above. Protect surfaces from brake fluid spillage.
