So I just finished replacing the master cylinder and booster bled the whole system except the clutch. And took the car out for a cruise to celebrate having power brakes again. About 5 miles in I came to a right turn and as I was pressing the clutch in it fell down and white smoke came into the interior through the steering column. After this the clutch was super low but still worked so I pulled the car off the road and checked in the engine bay and didn’t notice anything wrong. Called a mechanic friend and he told me to try to drive it home and pull over if it happened again to get it towed. On the way home not only did I not experience the issue again but the clutch started to feel normal again. Any ideas? Everyone I’ve talked to thinks it might need to be bled but no one can seem to explain the smoke.
