Brake peddle pulses over bumps when braking
Anyone know what would cause the brake peddle to feel like ABS is kicking in when braking and rolling over small bumps in the road? I don't have ABS.
The only work I did recently was pull off the drivers front wheel to inspect my suspension and put it back on.

I'd like to think it was wheel bearings, but I just replaced all four wheel bearings.. I'll check the rotor though. Who knows, maybe the lugs are loose or something simple. Could it be because the GC sleeves are shot and perhaps are rocking under braking?
New precision front bearings, timken rear, rpkg tie rod ends.

I've elected to pull my suspension and swap in my NB subframe+suspension as I'm getting the vmaxx xxtreme track pack delivered Friday after work, together with a full set of eccentrics from 949 I am hoping this problem goes away. However while disassembling things tonight I noticed my driver-front pads+caliper are grabbing more on one area of the rotor than the rest. In any case I'll update as more information comes to light.

Here is a video that i use to explain lateral runout, and thickness variation. it's a coppy of a vhs tape, but it explains it perfectly.

So far I'm still in the process of installing Grease Zerks and it's taken a lot of time; I just have my rears to go, then mount the rack+tie rods and bolt everything up.
4sfed5: I DO get a fair amount of flex, it's like the more I tighten things up, the more things I notice need to be serviced lol. I'll figure something up for the flex, might cave and get a premade since I'm so strapped for time.
duffbuster243: I have SS lines, however it could maybe be air in the lines, so I've opted to bleed them if the above doesn't work. It's good practice anyway though.
OG Racing: Good news: I'm swapping for NB uprights, so I'll get to see if those help fix the problem.
