Clunking when Braking Hard

[Kristeun]

Only happens in the rain when I'm stopping pretty hard, almost always when slowing down for a stop sign going down a hill. Hear a loud clunking from the front and feel it in the pedal. What would be causing this?

Check:

motor/trans mount rubber
CABs
diff mount bushing (yes rly)
caliper mounting bolts on front brakes

ABS still functional?

Oh yea forgot to ask. Could this just be the ABS doing it's job? Not really sure how it should feel? It's pretty loud though and only coming from the front so I assumed it's not.

Edit: Oh and I replaced the pads and rotors recently. Only did the rears myself though and the mechanic said that the front right caliper is getting stuck sometimes. Could this be the issue?

Sorry, have very little mechanical knowledge.

When the ABS engages, the brake pedal should sink down and vibrate.

That rather sounds like ABS activation on one of the front brakes. How good are the tires?
