Anyone know why my 1995 E320 would cause the brake pedal to pulsate softly/gently ONLY while turning right (into a parking space and slowing down), and ONLY at speeds below 10 m.p.h.? I'm told it's probably the right front wheel ABS sensor. Can anyone confirm this?

My personal experience with ABS is that it engages under heavy breaking. I've also had it engage while breaking over a patch of ice, probably doing under 10mph.

Right. There is definitely no ice though nor sand, Just slow movement while braking and turning right.

This sound like a right front ABS sensor.
When turning right the right front wheel turns slower than the left wheel, if the sensor is not working properly the ABS system thinks the wheel stopped turning.

Defective right front sensors are very common, mostly a broken wire.

Since you have this problem only when turning it may also be a dirty sensor, take it out and clean it first.

Right, thanks. That's what I thought it was but I wanted to make sure that someone else has heard of that before i spend $100+ for a new right sensor.

I would start with brake pads...just like a regular brake job...start at the beginning and work forth...I have my reasons for suggesting this...I'd be more than happy to expand if anyone is interested...otherwise

Well a new wheel speed sensor didn't change anything at all. I even cleaned the socket the sensor slides into. I also was due for a front brake pad change, so I replaced the front pads and rotors, and made sure the two pad retaining pins were in place. No difference, I still have a very slight brake pedal pulsation only when turning right (like into a parking space) and only at speeds less than say, 5 m.p.h. What gives?

I offered but you guys know so much more....change your front brake pads...you will no doubt find that whatever pad is left has broken off the the backing plate and is floating gently within the caliper ...it's crappy pads floating in the caliper and making it look like it's the ABS...like I said...just change the front brake pads...

I did. Read my post, both approaches solved nothing.

I replaced both front wheel bearings with the MB bearing kit (I did this because I wanted to - good experience etc.). While doing the bearings, I had the opportunity to remove both front hubs. I noticed the ABS grooves cut into the hub were all corroded and had grease and other crap all over them. I cleaned both front wheel hubs with a wire wheel brush and a drill. They were shining when I was done cleaning them. I was convinced this would solve my pulsation problem at really low speeds turning right. It did nothing. I even cleaned the head of the sensor on the driver's wheel of all its metal shavings. So far, I have replaced the front brake pads & rotors (because they were needed), the passenger ABS wheel sensor, and have cleaned the ABS rings. Anyone have any ideas as to why this is still happening?

What kind of shape are your lower ball joint and the guide rod mount in?

On my SEC the guide rod mount made/makes some interesting noises once it got pretty worn, as well as shuddering when turning at slow speeds.

edit:
I just re read what vehicle you're working on, after having mixed it up with a w126 I was just reading about.

I don't know if your car has anything equivalent to the lower suspension mountings of the w126 cars, but I'd check there, since you seem to have taken a good look at the brake system already.

Best of luck!

The control arms/ball joints appear OK/intact. No issues with them. This is definitely ONLY felt in the brake pedal, not the front end. I'm still trying to figure this out.
