all 4 new calipers and hoses and rotors ?
how bad will it pull ?
has the 4 wheel ABS been touched yet ?
was all that work done to correct this issue ?
nothing was done at all to where now you have this problem ?
with everything new all rotors and calipers and hoses and it still does this the issue should not be the hydro-booster but more so a fluid difference at the wheels which would cause a pull
if the ABS electrical connector is unplugged off the ABS unit will it still do this ?
if it does the only thing left with everything you said new and assuming no kinked or damaged metal brake lines is the ABS hydrolic unit assembly as the proportion valve and metering for the fluid to the wheels is all done inside that unit and it would need to be changed
yes you can unplug it yourself and it will drive normal just NO abs will work if you need abs on the road test
internally some debris can stick a valve or two or a week spring on one of the valves can cause this issue
it is not very common but we have seen this issue before
the only true was to be 100 % sure is to find an older shop that might still have a brake pressure tester to test the pressure at each wheel
but most of the time you are down to you have eliminated everything but the ABS unit
how are you making out ?
