I searched the forum and couldn't find anything like this.
Every time I press the brake pedal (while the car is moving) there is a loud click from the front of the car. It only does it one time per braking. No noise when I let off the brake.
I think it something needs to be lubricated in the front end, but not really sure. I was hoping someone could help. Thanks in advance.

 

What year ? # miles ? Any recent brake or suspension repairs ?

If not a brake pad fitment (pads loose in the caliper / anti-rattle shims not installed) issue another source of a clicking sound when braking is worn control arm bushings.

 

The worn control arm bushing should be the culprit based on the sound.

It's a 2005 545i with 77k.

No recent repairs. The brakes have been maintained.

Thanks for the reply

 

i had this same problem right after i took my car in for service at the stealers... i never had the clanking before, and when i was gettin my car back, my SA told me the control arm bushings were cracked and that they would fix it for $800 i think they're like $100 for the parts!! anyways, it clanked for a week or so and eventually went away... i'm still convinced the stealers had something to do with it as i have no warranty and they have a huge smile on their faces every time i take the car there hopefully your's is just a "phase" as well...

but either way, check the bushing, if they're the culprits, look for an independent shop to fix em cuz $800 is highway robbery IMHO

part number i believe is 31120305612 @ $98.93 for a pair


or a quick google search gave me this:

but find out if its the bushings for sure before you buy because I'm no expert here!!

 

Thanks! I'll take it to my independent shop and have them check it out before I buy any parts. I appreciate the advice!

 

This happened to me on an older 5 series. It scared the crap out of me because it was such a loud bang every time I broke. The harder I broke at higher speeds the louder the bang. An engine mount had cracked and broken so everytime I broke the engine would bang off the chassis. Costed ?130 including labour.
