Y reg L&K , 50,000. Bought recently. With car document showing that alignment had just been checked/corrected. Car drifts gently to right , can climb slight camber of road.. Swapped front tyres over. Still drifts. Doesn't pull to one side under braking.

Any suggestions about what is wrong & how to fix it ?

Is it on one particular piece of road?

I'd imaging you're on 205 tyres... can be quite prone to tramlining.

Tyres Goodyear Excellence 205/55 R16. Type of road does not seem to make a diifference.Checked temp of disks, rear cool, nsf hot, osf v hot. Test by finger touch - ouch. Perhaps osf brake binding - cure ?
