Not just doing the anti-lock dance, is it? Do you hear odd noises from under the hood while its going on?

 

That's hard to notice the diesel is so loud I couldn't till you for sure. It hasn't been a smooth feeling pedal for quite some time now. When you depress the pedal it vibrates a lot when you press hard on it. It's worse when you are steering and braking at the same time witch Is a sign that it's low on power steering fluid. I'll full it and it's better but there's still the vibration in the pedal.

 

How do your rotors look?

 

Anti lock dance...My 98 did it after a full brake job.
