R32 Clunk then Brake Pedal Pressure Drop

[Matchew]

Hi,

I have a small problem and I was hoping some of you here might be able to point me in the right direction.

Tonight I was about to leave my Girlfriends house, so I started the car as normal and put my foot on the brake pedal to put the DSG into D. As I did this once the brake pedal reached it's normal stopping point there was a loud metallic clunk from under the front of the car, then the pedal seemed to drop further than normal.

The brakes are still there when I drive the car, it just feels as though there is suddenly more pedal travel available and required than there has always been before.

I had the 60k service done in may and they replaced the front pads and rotors, so if all else fails I will be returning to the dealer to have them check things out. I had been driving the car all night start and stop and had no issues until this one time. I haven't tried to start the car and put my foot on the brakes again to see if it repeats.

If anyone has any suggestions as to the cause or solution it would be greatly appreciated.

Thanks.

Maybe it was a sign ~ Your brother R32 was telling you to stay at your girlfirends overnight

Just thought i'd sub to this, as I get this sometimes when coming to a stop, and could never explain it like you have. Let me know what you find out.

maybe a caliper bolt snapped?

Buzuki, I think you're on the right track, my girlfriend rang this morning and told me she found a bolt in the driveway where I was parked. Time to make a phone call to the dealer principle where my 60k service was done. I'm not impressed.

This is the bolt that fell on the driveway.



Seems the service department don't know how to re torque bolts after they replace things.

If anyone can identify where this bolt may have come from, presumably somewhere in the braking system, most likely a caliper retaining bolt, that wold really help my conversations with the dealer. I've spoken to them this morning and the dealer principle is trying to tell me 5 months is a long time after a service for something to go wrong. I'm not buying it.
