What The Hell Is That Tapping Noise

[E36k224]

when my foot is on the brake pedal
I can feel a slight tapping
It also makes a tinking noise about every 5 seconds
It drives me insane! ghead

what the hell is this?

have the DSC/ASC lights ever come on or the ABS light? are the catalitic converters original? try putting the car in gear and pulling up on the hand brake until the car stops and see if it still makes the noise. if it does then it might not be in the braking system. it could be the cats. going bad and starting to rattle.

even if it was in the brake system the handbrake and pedal brakes operate two different ways, so it could still be in the brakes. I notice a clicking noise in my brakes when i depress them but it only happens once. i think it basically tells the abs system to watch for slipping wheels once it is pressed past a certain point.

sorry if this is a little off topic, but my abs light turns on sometimes for no appearent reason while i'm driving. i've never heard any wierd noises, and tried testing my brakes while the light is on, and the antilock system seems to be working fine, is this just a bad connection in the sensors that make the light turn on??

i know the hand brake and the rear brakes operate diffrent from the regular brakes thast why i said it. if it IS the actual brake system you could find out by pulling the hand brake up, and if the noise doesn't happen then you have narrowed it down to the brake system. and the ABS system is always active to watch for slipping, no matter how far you push the brake pedal. the BAS module looks at wheel speed at the whell speed sensors.
