hi every one on the forum. i have a 1997 honda accord. i recently had both front disk changed. the problem now is that after u turned it on and start driving is makes a sound like something is loose and the break pedal pulsates a lot when braking, after few minutes, the ABS ligh comes on and break pedal stops pulsating and the noise that something is loose stops. car breaks still breaks with out a problem...anyone might know what the problem might be?

 

It is spelled brakes not "breaks".

 

Check ABS Fluid. Make sure cap is snug.
Also Check Brake fluid.
