brake rotors and pads

After 12 years and 41k miles, my 2003 540 looks to be needing some new front rotors and pads. I am starting to notice some faint vibrations when braking.

What's a good brand(rotors and pads) to get? I have a 2003 540 M sport model.

After 12 years and only 41K, this vibration could be due more to leaky thrust arm bushings rather than rotors/pads. There are many differing opinions on pads. Search for them.

Suspension is certainly something to look at ... but ... I ... for one ... would look more directly first than indirectly ...

As Fudman alluded to, lots of things can CAUSE vibration, but, if it's BRAKE-related vibration, the FIRST thing I'd consider is the most common (Occam's Razor) which is that YOU (the OP) caused the vibration (by your braking habits).

It's almost NEVER the rotor, by the way, although the temporary cure is almost ALWAYS the rotor (while the long term solution is for you to change your braking habits).

Such are the riddles when you begin to UNDERSTAND the enigma.

My 530i steering started shaking a couple of weeks back.
I got under and found I could twist the tension arm by hand.
Replacements are going in shortly.

The OP may well have pad/rotor issues, seems a logical 1st place to evaluate. I have personally experienced shudder/vibration when braking and it was in fact due to the brakes, mine had more miles by a ways than OP but ALL shudder went away upon installing set of new pads and rotors.
His car looks like a Sunday driver, how lucky! I'd say stock brake components are fine, unless his weekend drives are in the racetrack

Exactly. My wife's Mazda CX9 had this same symptom last year. I change the rotors and pads and it has been vibration free since then.
