Evo X

On the exit of a corner, I dipped what I thought was the left rear of the car off the candy stripe into the dirt, but for all I know it could have been the left front or the entire left side. As soon as I got back on I felt vibration from the steering wheel at speed that had not been there before. My brake pedal also became softer and brake fluid was slowly leaking out of the driver's outside bleeder nipple.

In the pits, I took off both left side wheels and checked for loose components. Nothing. I bled both nipples of the driver front caliper and regained some brake feel. I then reinstalled both left side wheels and torqued them down. However, going back on the track, I felt the vibration in the steering wheel at speed again.

What do you guys think the problem could be?

 

Best guess: you threw a wheel-weight and it hit the caliper in the nipple.

(And now the 14-year-old boy in me will go have a giggle at the sentence I just wrote.)
