clicking sound when braking

My daughter's 97 6 cyl Malibu makes a clicking sound when you hit the brakes. I read somewhere that this was happening and the dash lights were dimming at the same time, so it was a battery or ground problem. We aren't noticing anything but the clicking when you hit the brakes. My husband thought maybe a brake light was out - but we checked that and the lights are all working when the brake pad is engaged. It seems to be coming from inside the car - it doesn't seem to be coming from the brakes themself - which are all new by the way.

Any ideas?

I had something similar but that turned out to be one of clips on the calipers being installed improperly; but if you say its not coming from the brakes that might not be the case. The lights dimming isnt anything unusual though, mine does it too.

Does yor Malibu have ABS?

Does it happen when you brake at a corner or when in a straight line?

Sorry for the belated reply. Just to update - yes the car does have ABS brakes. Found that the left caliper was locking up, so my husband replaced that - and whether a fluke or maybe just an intermittent thing, the clicking has stopped completely - so unless it starts again, it may have been the caliper.
