Default Possible ABS issue

SI since I bought my 2000 DTS I've had an issue with if I brake moderately hard the car dives to the right after letting off, back to the left. Usually after a brake service the problem goes away. After some recon however I did notice some fluid around the ABS motor on the subframe. So anyone have experience with this?

If the brakes were serviced recently(replaced) then its possible a line was ruptured while the pistons were pushed back into the caliper. I highly suggest NOT to drive the car until this leak is found and repaired. You are probably only using 60% of your brakes.

Sounds like a internally collapsed rubber brake line to the caliper or the caliper itself on the left side. Good way to check is jack the front end of the car up. Apply the brake pedal and spin the front wheels.

Usually with a fluid leak, the brake pedal will fall to the floor all the time.

Yes, and yes I know not the smartest idea, but really don't have too much of a choice. Another symptom I think my be related is two things a slight vibration that seems to be coming from the passenger side and when reversing out of a parking spot I sometimes notice a creaking noise from the passenger side, starting to suspect maybe the axle is the culprit, there is a fair amount of axle grease on that lower A Arm

That still doesn't account for the possible brake fluid you found around the ABS unit. I highly suggest you get this to a shop because we aren't going to play guessing games if your not going to get something looked at.

Sorry for not getting back my recent move to Vegas got me sidetracked. So, finally got the thing up on a rack up here. Turns out it wasn't too complicated there was a blown bushing on the passenger lower control arm. Replaced it that issue is gone. So down to the next problem at hand, have way more vibration in the wheel then a caddy should. That and the service suspension light came on, I converterted the air ride in the rear with the Strutmaster conversion kit was thinking of doing: Monroe or KYB ready mount front struts, new hub on the passenger and possibly the axle. Any other suggestions? That and was curious if there is a resistor to override the system like there was in the rear for the air suspension, thanks for the advise

kyb tends to be a tighter ride valving than monroe, depends what you want. monroe is a floatier ride. no sure about the resistor. vibrations are normally brakes, bearings, tires, rack parts/rod ends, or bushings, like control arm, or subframe mounts for the control arms if your car has that
