    Hi Friend: I need more information to beable to help you. Did the Brake pedal just go all the way down to the Floor ? Do you have any brakes when you pump the brake pedal? Can you see any Brake Fluid on the inside of all your Wheels? Is your master Cylinder (where you add Fluid Full or not?       Please tell me how or what happen when your brakes stopped working,And was there any Noises when pedal was pushed down.                 I'll be Glad to Folow up after you give me some more Information.   Thank You:

Hi again: I'm almost 100% its your Master Cylinder has gone bad.And needs replaced. Should solve your Problem. After you Change it and have the New one on,You'll need a Couple Quarts of Brake Fluid, Cause you'll have to bled the Air out of the System, and 2 Qts so you can Flush out ALL your Old Brake Fluid its probally contaminated. To Bled Start at the Passenger Rear Wheel, next Drivers rear Wheel, Next Pasengers Front Wheel,And Last Drivers Side Front Wheel. You'll need a Helper for for 2 reasons 1st reason he wil need to push the Brake Pedal to the Floor HOLD it UNTIL you Open Bleeder Valve and leave open until no more Fluid or Air is Coming Out, Then Close it do it again and again,Then Go to the next Wheels as i told you above and repeat the same thing on each wheel but do it in the order i told you above. 2nd Everytime you open the Bleeder Valves and Fluids coming out ,Your Helper needs to Keep checking the MASTER Cylinder and Keep it Full ALL the TIME. or you'll get AIR in the System and the Bleeding will not Work, Without a Full master as you Bleed the Brakes. Continue doing this until you See Cleaner Brake Fluid Coming out ALL 4 Wheels Bleeder Valve. Remember KEPT THE MASTER CYLINDER FULL. AND ONLY have your HELP PUSH the PEDAL down even to the FLOOR DON"T PUMP IT> You'll get a Pedal as soon as you have Continued to Keep Bleeding the System. This should Solve your Problem.

SOURCE: I need to replace the

Husband found it but it did not solve the problem. But we can now hear the pump energize but the car still will not crank over and start. It acts like it is going to but just dies right away. This problem first started whenever I would go up the slightest incline, it would start running rough. Then on level surfaces it would go back to running fine and then one day it just would not start. Any suggestions?

More than likely (and we will hope) it is the oil sending unit. In comparison it is a very cheap and quick fix to replacing the oil pump. Auto Zone has a pretty good componet location section that has tips for replacement if you cant find the sending unit or the oil pump. Try that first it may save you a lot of work.

What is a vaccum leak on a 1999 buick regal

All engines have vacuum created in the intake manifold, because the pistons are pulling in air into the cylinders from the intake manifold, resulting in a pressure drop in the intake. A leak is caused when the intake manifold gasket is bad, or when a vacuum hose off the intake becomes disconnected or breaks. The hose will then **** extra air into the intake, causing a higher than normal idle, maybe a rough running condition, and can be identified by a slight whistling noise at the break or at the disconnected end of the vacuum hose.

Think about it, you are creating a direct SHORT in your seat to create heat. So yes, it can happen. Luxury stuff breaks. Id still bust the balls of the dealer or maybe try talking to your car insurance. They might know how to get that fixed by buick instead of by you.
