Just got my first benz! 1986 300SDL



I still kinda wish I could've found one in graphite or black, but this is pretty classy, and cops won't bother me as much!

I have two or three gripes that I've noticed since i picked her up:
(before I complain too much, she was only $2800 and has only 161,000 mi!)

The climate control never changes between feet, vents, and defrost. I assume there are probably some vacuum hoses that have dried and cracked or something to blame for this

The brake pedal occasionally vibrates when I'm coming to a stop. But its a really rough, jagged sort of vibration that worries me a little. The guy I bought it from said he had just done the brakes himself. That actually worries me a little since he didn't seem to know much about the nature of these cars!

It's also characteristically slow, but it's been getting better since I drive on the freeway a lot. The guy I bought it from didn't drive it very much at all except for little trips here and there. For a diesel that is torture!

Anyone have any suggestions for things I can do to fix any of these things?
Also if there are "must see" or "must buy" items for a new w126 owner, please direct me!

-Thanks!!!

Does this happen at real slow speeds?

There are wheel speed sensros for the ABS.

Pull them and clean with brake cleaner also spin the wheel and spray inside the sensor housing.

yeah really low speeds. that sounds like a likely cause, I guess if the computer thinks the wheels are moving at different speeds, it would activate the anitlock. the antilock light has been coming on intermittently also, i guess thats probably why!
Thanks for the tip!!
