Question Brake pedal pulsing

hello, I am interested in finding out why is it when I push the brake pedal I can feel it pulsating. I have a 1999 lincoln navigator with a 5.4 litre eng and it is all wheel drive. I have just changed my brake pads figuring that would be the problem and that didnt work. I only have 120,000 miles on it. does anyone out there have a solution to this problem? Thanks

I'm thinking your rotors need turning or changing but that is just my first thought. Hang in here for the pros for a qualified answer.

Warped rotors if the pulsating occurs when you're moving. If this happens when you're sitting still it could possibly be the ABS.

The ABS works on a rapid application/relaxing of the brake pressure to avoid lockup of tires. That type of of pulsing is much faster than a warp rotor would produce.

Hope this helps,
