"Weird" feeling in left foot during braking

3erdrive · 07-23-2011, 11:09 PM

Hey all, my E93 JzB (I will post pictures in a new thread) feels.... unusual during deceleration/braking, the best way to describe it would be like if the floor underneath my left leg during driving (damn dct! Not involving the other foot) is rumbling and vibrating, it's an unusual feeling and I've never felt it in the 335i. Is this normal, or was there an issue in PDI?

are you braking hard enough to involve the abs?

Do you feel the same if you use your right foot?

I saw this on a different forum, but this lady had the same problem as you.

Are you left-foot braking when you feel this?

I am braking as normal. My left foot is resting flat on the floormat.

Sorry, I have no idea. The reason I ask, when becoming acclimated to left-foot braking, the ABS intervention under threshhold braking feels a bit different, as does everything else until the left foot is trained.

I think you have brake pad material on your rotors.

Does the petal Pulsate at all when braking? Is this during Highway braking or intown? If you brake on the highway or at any speed really, if you remove ur hand from the steering wheel or just gently hold it, does the steering wheel shimmy and/or shake under braking?

Your left foot is going through withdrawal and is convulsing a little. It's tough you know, for it to come to terms with the fact that you don't need it to do a rev-matched downshifts while decelerating anymore. Perfectly normal. It will go away soon. Either that or it will wither up and fall off. Either way - problem solved.
