Horn blows when Braking

[RandallNeighbour]

"My horn blows without my help" brings back a lot of memories. This was my first repair. Cost me $200 at the stealership. I didn't learn about the rig-fix until much later in Boxster ownership.

Now I have a 3 spoke and that doesn't happen to these wheels from what I hear (or don't hear).

Thanks so much guys for the good info. What an annoying problem !
