Question about 1999 Daewoo Lanos
First make sure the threads on the flare fittings are in good shape... I've saved a few with a thread file... if the threads going into the master are messed up, My advice would be a new or remanufactured one. start the fittings before you tightem the master to the booster... much easier to get them started... don't force 'em or you be back to where you started

Honestly your guess is as good as mine. But I don't think the master cylinder is NOT bad you still have air in the system. Get a big bottle of brake fluid bleed all four sides until you run out of fluid or your brakes work properly. You should divide the bottle's content in four, then use each quantity in each side. You'll be removing air and contaminated fluid from the system. Get a small hose that fits on the bleeders and an appropriate container. I have a good feeling if you do this your brakes will work just fine. I don't know how you are bleeding the brakes. I'll let you know the proper way just in case. This is a two man job, with the wheel off, have someone start the car. Have them pump the brakes a few times to get pressure. 1With the brake pedal UP open the bleeder, 2then have your assistant press the brake pedal all the way down and leave it completely pressed down. 3Close the bleeder valve, once close and only with the valve closed have'm release the brake. Repeat as necessary, bake depressed, open valve first then press brake. DO NOT depress until valve completly closed. Close valve THEN depress. Good Luck!

Did your mechanic use a DRB III or equivalent scanner before performing the bleeding procedure after installing the master cylinder? This is a requirement by the manufacturer (Chrysler) when bleeding the brake system.

SOURCE: no brake pressure
There IS one place it can still leak. behind the brake master cyl - into (inside) the power brake vaccum booster, although that doesn't seem the problem. You first need to make sure your master cyl is bench bled. with a hose bleeder kit, you can bench bleed in-car. you should be able to bleed sys through abs sys with no problem. Sounds like the master cyl needs to be re-bled.

do u have the antilock brake bleeding tool? if not you will need to have the dealer bleed the brakes, the ABS control valve must be electricaly held open to bleed the brakes there of course is a special tool for this.
