While driving there is a constant beeping sound but as soon as i hit the brakes the sound goes away only to return when i release the brakes. I had new brakes installed on all four corners last year this time. It been 23,000 miles and I checked brakes and they look half worn. Rotors dont look so good.

1. Is this beeping sound the brake sensor?
2. Plan on replacing with Centric rotors and Centric ceramic pads. Is this a good option.

 

could worn out rotors also cause the brake sensor noise to go off.... car has 95,000 miles...

 

Brake sensor???? thats a new 1, what year????

 

Its a 2004 Vanden Plas.... The beeeeeeeeeeeeeeep or innnnnnnnngggggggg sound can even be heard after i turned the car off for a few seconds then it drowns out.

 

theres no brake pads sensor on your car. its something else. what warning lights are on or messages in the display?

 

There are no warning lights on the in dashes message board... i figure it atleast has to do with the braking system since everytime i press the brakes, even the lightest touch the sound disappears. I think i might have to record a video and youtube it!!!

 

well thats what I need to here, I susoect the noise is under the dash and is coming from you brake booster....you have a vacuum leak in the diaphram that leaks when stationary. The fact that it goes away ":when you push on the brakes" is the tell tale...Slide under the dash and listen to solate and press on the brakes. The only thing I know you could try short of having the brake booster replaced is to spray thick lube like lithium grease around the push rod for the brakes where it goes into the booster at the inside firewall

 

Went for a short ride and after about 5 minutes the humming noise started. When i returned home i left the car running and opened the hood. Opened the compartment to where the brake fluid resevoir is located and BINGO!!! There was where the annoying whistling, iiiinnnnnnnngggggggg, beeeeeeeeeeeeeeeeeep noise was coming from.

Thank for the help.... plan on getting this fixed as soon as possible

 

Brake vacuum assist cylinder or the vacuum hose going to it.

 

You need to ask this question in the S-Type forum.
