My '67 OTS will pull to the left OR the right when just starting to drive (even on warm day). Once I've been driving a bit, problem goes away and there's no more pulling to one side or the other.
Replaced master cylinder recently to remedy problem but this has had no impact.
Could it be vacuum servo? Don't seem to be losing any brake fluid but I've heard that even a small leak in the servo can have bad consequences.
After decades of driving civilian cars, I got back into old English cars a couple of years back. Used to work on my '59 TR3 and my father's '56 XK140 when I was in high school in late 60's. Currently have the '67 OTS (restored 20 years back by previous owner) and a '66 FHC (lots of miles but nice shape).
Thanks for any help with this unusual problem.

Hello Joseph
Have not checked front wheel bearings for at least a year. Will do so this weekend (and will check ball joints). Thanks for the tip.

Henry,

Master or booster cylinder problem would affect both sides equally. Have you checked clearance of front wheel bearings?
