Brake Light Switch ABS/BAS/ESP
i swapped out the brake switch last night.. and took it for a spin no more errror messages thank god!!
but i still have some vibration in my brake pedal... help please... anyone go thru this?
I think his 99'' had coil springs and shocks . my 2001 doesnt have airmatic ride .
lil update i still have the problem
its not from rotors or pads its my abs unit...
ive disconnected my abs so basically driving around in dyno mode... car actually feels way better in dyno mode lol
but anyways in dyno mode i get no pause no vibration in the pedals brakes are nice and smooth how it should be
im thinkin i have to replace the lines that run underneath the car... because this started happening after i got stuck on some rails and i think maybe the lines got pinched and is makin the abs go haywire...
anyone else have any advice? or have done repairs to their abs unit?
thanks in advance

Looks like I'm going to be driving my POS Durango until I get this taken care of.
BTW, 2003 was the first year for Airmatic on the E Class.
I took the car out a little while ago and the problem didn't happen again. I'm still going to replace the brake light switch on it anyways. It's cheap and at least will let me know if something else is going on.
Now if I could just figure out the vibration that I randomly have. It seems like it started when I got the car lowered (everything is installed correctly) so the stock springs are going back on in a few weeks.

As, you know once a car is lowered it adds stress to the front end. I would check for any play in the front end before going back to stock as it would stink if the vibration didn't go away after going back to stock.

My steering wheel shakes even more when hard stopping, it goes nutz. I'll prob. won't even do the rotors till next spring as winter is around the corner and I keep the car in the garage. (she got enough work to her done this year)


Just to clarify, my vibration is not related to the brakes at all. They need to be done soon, but they're still smooth.
I'm also thinking it might be tire related (Nitto NT55's with about 2,000 miles on them). I'll probably try swapping my stock wheels back on before changing any other parts just to eliminate that.

I also picked up a new brake light switch today. $35 at the stealer for it. I didn't feel like buying it online just to save a few bucks.
Hi all-
Thanks to the great tutorial, I was able to replace my brake light switch ($24 at Walnut Creek MBZ). I started the car, excited to (not) see the ABS warnings, etc. No joy. Still have the warning as soon as the brake pedal is touched, and no brake lights. Next steps anyone?

For quite a while my ESP BAS light has been glowing so no cruise control but what I did not know was that I had no brake lights working
I had it plugged in and they suggested a new brake switch
I replaced the switch and checked the fuse to the brake lights ( fuse ok)
On restarting the car the warning lights remained on and the brake lights were still out.
But after several hours and restarting the car the warning lights went out and the brake lights worked correctly.
This only lasted 2 days and I am now back to square one with warning lights back on and no brake lights !!!!!!
Any bright ideas ???
