Taiman, It sounds like you have a vacum leak. Does the engine idle a little rough and smooth out when you accelerate? Try this little test, get a empty spray bottle, fill it with warm water, the add one tablespoon of dishwashing liquid, put the sprayer in and shake it up, then run the engine for a bit and shut it off and start spraying the solution in the area of your noise and when you hit it with the spray the noise will stop or change for a second. That will show you where the leak is and all you will have to do is repair it. Good Luck. quicbric (the volvo man)

Brake problems


by repressurize, do you mean 'pumps up'. If everytime you hit the brakes (allowed to sit for a few moments between uses) it starts applying the brakes near the 'normal' pedal position, then it sounds like the master cylinder has gone bad.

Other less likely causes, lots of water got in the brake fluid (assuming nonsynthetic brake fluid) and has turned to junk.... Might try power bleeding the system, but my bet is the master cylinder.

Peace,

2001 Chrysler Concorde pressed the brake


That sound you hear is coming from the Vauum Brake Booster...Sooner or later the Brake Pedal will get hard, because the seal inside of the Brake Booster is leaking..And the only way to repair it, is , to replace the Brake Booster...But also check your Vacuum Hose that is instaaled on your Brake Booster..It goes from the Brake Booster, which is behind the Master Cylinder...From there to the Intake Manifold...Just make sure that there are no cracks in that hose, and make sure it is on all the way...because if the hose is bad, then thats all you will have to replace....Goodluck...

Brake light on, power brakes seem gone


Chk. for vacume to booster, or loss of vacume like a break in vacume hose, do you hear a hissing noise when you step on break peddel. If you don't hear anything chanses are its the booster. When peddel gets hard to push you either lost vacume or booster went bad.
