Yes. But the mechanic who replaced the brake line should have done it before it even rolled out of the service bay. Your power brake booster has a vacuum leak if you can hear it.

OK...here is a simple way to tell if the power brake booster is bad. Get behind the wheel and pump the brake pedal until all the reserve is gone ( engine off ) this usually requires 3 to 4 pumps...after the pedal is hard to push down ( reserve gone ) hold the pedal down and start the engine.....you should feel the pedal move down with the pressure you are applying....IF this happens...your power brake booster is good. If you had air in the brake lines the brake pedal would feel " mushy " and soft. I hope I helped you.

Brake booster makes a hissing noise when the diaphram is bad. Ready for another repair expence? I have never heard air in the brake hydraulic system but I do notice spongy brake pedal. When bleading brakes follow manufacture bleading procedure. Each car is different. And bleed to clear clean fluid at each wheel. I start by empting the resv with a turkey baster or syringe. Fill the resv with fresh clean fluid from a just opened bottle. Then keep an eye not to empty the resv between each wheel bleeds.

Yes, that air noise would be the power brake booster. It doesn't mean anything is bad or broken, maybe just working better than usual with the tweaking done recently.
If the brakes are working without the pedal hittoing the floor then there shouldn;t be any air in the brake lines.
Good Luck!.

No the swap isn't impossible, but in short, they will not work. You can do anything you want if you have the money. Do some research, find another car made off of the platform you are using. Drum brakes are very effective on that car. One of the reasons disc brakes are used is because they tend to dissipate heat better than drum brakes. Drum brakes provide more stopping power, per square inch. That's why you see them used on semi trucks, they can haul 120,000 pounds, and stop better. A properly adjusted set of drum brakes are fine. If you are looking for power, get a wrecked supercharged Bonneville, and use it for the 3800 supercharged engine and transmission. That would be fun. The swap isnt easy. I have done it to a 1988 Lesabre T-type, it is a bolt in application, but the wiring is complex. It isn't for the average person to try to take on.

you wont be able to hear the air in the brakes, if you do hear air when you mash on the brake pedal,its the booster that's going bad on it,but it might be a good idea to re-bleed all the brakes,but the air your hearing,isn't from the lines,good luck ,hope this helps.

Any time you open the brake system and replace anything you NEED to bleed all wheels.Just to make sure all the air has been removed.This is done for your safety.
