What a great feeling to have a perfectly working braking system. I replaced the front rotors, calipers and pads, it turns out I had a stuck piston on each caliper that was causing the rumble when braking. The rotors and pads were worn bad. Of course it didn't go smoothly as two caliper support bracket bolts snapped, I had to ride my moutain bike to the auto parts store and replaced all 4 bolts with new ones. It was well worth the $300 in parts, now to replace the struts and springs.

Good work! Always feels good to successfully complete a car project. Good luck on the springs and struts.
