whats up w/ my brakes

[WickedGen3]

ok.. i found out that i have abs on my gen 3.. now my question is that.. when i brake ( 20mph-30 mph or sometimes under 10mph) and i hit a bump/pot hole. the wheel seems to be shaking.. and the brake also shakes like it has lost control or something.. don't know why .. is there someting wrong with it? i check and i got plenty of brake fluid.. i don't think my car uses any of those brake fluid.. i had them bleeded last year and now its still full.. i'm using DOT 4.. if it matters.. i mean.. thats the only thing bugging me..

this has happen also when i'm at speeds of 50-60mphs.. if i hit a bump on the road.. it will shake and the car can't slow me down as fast ! . ...
can it be the master cylinder or the brake booster??

thanks in advance guys

warped rotors? been braking hard lately?

also have u ever felt the abs at work?? i mean it does shake a lot because of the brakes doing an on-off sequence in a matter of seconds... to prevent the brakes from locking... if u just serviced ur brakes have ur rotors and pads checked out for consistency ... i mean new pads/ new(machined) rotors

get a suspension check
sounds like the tie rods or the ball joints

Yea sounds more like suspension problem than brake problem to me.
