need help with my breaks!!!

Ok so this is my first thread on here. I own a 97 bmw 540i and i been noticed that my breaks were rattling in the rear. So i just installed new breaks in the frount and the back i use break grease and the noise went away for a while but it came back. so i took the breaks apart and greased up everything up again and the noise went away but after a week the noise came back. I did noticed that when i took the breaks apart that my inner brake pad was loose that i could make the same noise by moving it with my finger as driving down the road. My question is that why did it come back? Is there a way or procedure to install the breaks so that they don't rattle? I have all 4 anti-rattle clips installed and all the breaks are brand new if someone could help!!! thanks!

Welcome.

My very first thread here was also a brake thread so you are just like I am (or was).
- One user's example of a complete brake job with all torque figures, specs, measurements, fluids, decisions, tools, tricks, mistakes, suppliers, costs, etc., that it entails (1)

The veterans made good-natured fun of me in my first few dozen posts (their well-mannered criticism was well deserved) ... and I'm gonna likewise make fun of you (see below, just as deservedly) ... but if you continue to read and learn, you'll do just fine because EVERYTHING I ever needed to know about doing brakes properly we put into that thread (some of which will be covered below):

They're called B R A K E S (not breaks).

The reason it matters is because written communication is the medium of this forum: out here, you ARE what you WRITE ... (and you probably don't really want to know what we think about you when we see you consistently use the word BREAK for BRAKE because you have to be worth teaching for us to expend the energy to try to teach you).

BMW clearly says NOT to use ANY grease on an E39 brake job:

What do you mean by "all the brakes" are brand new?
- new calipers?
- new pads & shims?
- new shoes & springs?
- new anti-rattle clips?
- new rotors?
etc.

Doing a search for E39 "brake noise" in the forum, you may find one of these useful:
Brake noise from right rear. SOLVED
Weird Brake noise
just did my brake pads but im still getting noise tssk noise
brake noise
What the? Brake noise on new pad & rotor
brake noise
Weird noise (i think its coming from the brake)
Help With Brake Noise...
brakes noise and brake pads
etc.


PS: Whomever I chastise, I still offer to help, because attitude trumps ignorance.

You need to remove the inside pad and spread apart the metal clips that push into the caliper piston. Make sure you spread them far enough to make a tight fit.

No hard feelings I was working night shift when I wrote it. But I I just bought the car a couple of months ago and it was making the rattling noise. So I changed out the brakes in the frount and back I used the grease and spread it in the back of the pads. A week went by no noise then all off a sudden it came back any ideas?

When you say you have 'noise', does it happen only when braking? At all speeds? When you brake at slow speed on bumps?

Is it a rattling noise?
Is it a high-pitched squealing noise?

Did you replace the rotors?

Did you run a 'bedding' procedure when you installed the pads?
