Brakes or suspension compenents (bushings, tie rods, etc.)?

warped rotors and/or unbalanced tires.

thanks for making a vastly vague question then expecting a direct and concise answer.

How is it vague? When you brake, you can either feel vibration through the pedal or the steering wheel. I just can't remember which symptom matches which condition.

brake pedal would be rotor, steering wheel would be bushing, tie rod, control arm etc

My experience: Unbalanced Tires. And it is the cheapest way to fix. If you have warranty for tires, the shop should balance tires for free. Hope that helps.

grind your rotors down or get some new ones

Generally speaking......

On (almost) any car, if vibrations occure in the steering wheel while applying the brakes, it is due to bad front brake disks, the pads should be changed also (highly recommended).

Specifically on E36's, it could not only be the brake disks, it could be the front control arm bushings (rear bushings i believe).

100% agree, I had exact same problem, f***ed front rotors. Changed them 6 weeks ago, vibrations stopped.

Believe in us, it is front rotors. When you change them do wheel balance.

definitly front rotors, had the same problem on my last e36

As we speak, im doing the front and rear brake disks, along with new pads (front and rear).

Althought the disks don't have much grooves in them, and the run out are fine, they are in terrible shape once you take a closer look.

The front disks are not flat, if you feel them with you're finger, there are some high spots on them, like a wave (lower and upper parts of the disk are the same, the middle has this raised area if you will).

Also, they have been skimmed well over the limit. This is what happens when you let a company driver take you're car out to get a 'brake job'.....

Did i mention how everything was ovr torqued? how wrong everything looked?.......it's a good thing im such a major DIY-er and use manuals for torque specs and lots of copper based grease ;)

Thanks guys, I'll get them machined and get new pads.

Make sure that before and after skimming that you still have enough disk left, i do not know what is the limit, but make sure on this.

I'm sure the shop won't machine it past minimum rotor thickness.
