After swapping to Brembos the wagon is pulling to the left a bit. It's been in for alignment twice now and its spot on apparently, yet still pulls left (steering wheel centres off a bit). The Brembo parts came of a straight car, so its not that. The calipers are not binding either. Its not very bad, but on a long journey gets a bit tiresome. Tyre wear is consistent.
Any more ideas people? Ta.
