Squiggly Brakes

[justin_boy]

Hey Guys

Been having some problems with my brakes recently

about a month ago i had z1 stainless steel lines installed on my akebonos about a month and right after install i noticed if i was pressing my brakes between 10%-50% my steering wheel feels shaky, then when i get harder on the brakes its smooth until it gets into ABS

the problem went away for a little bit but then just recently i installed a brake master cylinder brace and also carbotech xp12 fronts and xp10 rears, and went to buttonwillow

i felt the same thing, even though they're breaking fine, they it is shaky in mid braking

just ordered z1 2 piece rotors front and back to see if that will remedy it cause i thought maybe the rotors are hot spotted or warped,

but can anyone tell me what they think this problem is?

thank you
