I have a 2005 Legacy 2.5GT. Great car..but it is my first Subaru. Upon repeated braking, such as the descent for a mountain, I am encountering steering wheel wobble upon braking....very similar to rotor warpage. Subaru insists that the rotors are perfect. This only happens after repeated braking and usually at higher speeds. It will not occur in around town driving. Anyone encounter this issue with any Subarus??????

I'm having the same problem on my 1992 legacy actually. Much worse around 120 - 130 km/h. I figured it was warped rotors, but not too badly to be concerned about.

The brakes were more then likely not bed in properly. What happens is pad material is unevenly distributed on the rotor, and when you heat up the brakes good, the coefficient of friction is different between the pad material on the rotor and the rotor itself, so you get the shudder you're experiencing.

 

I'm assuming your GT doesn't have too many miles on it, so I doubt it's a "warped" rotor.

 

To properly bed brake pads, you need to do about 10 consecutive 60-10 mph stops by applying firm/medium brake pressure. You don't want to jam on the brakes, but you don't want to do light stops either. Drive around for 15 minutes to let the brakes cool, (during this time, try not to leave the brakes applied for an extended period of time, like at a traffic light. This is a contributor to uneven brake pad deposits.). After that 15 minutes of cool down, repeat the 10 consecutive stops, and cool down.
