TR6 Brake Bleed

Bleed the brakes last night on the TR6 in an attempt to fix the pulling issue. After the work, the car is still pulling a bit to the right but not near as much as it was. Only thing I can figure now is that the caliper on the front right is sticking. Guessing that the pistons have gone a rusted to the caliper much like the fronts in the TR4 did. I am going to put in a few more miles this weekend a see how the brakes hold up. This will determine if I go ahead with the 4 piston upgrade for the front brakes or if I can hold off on that. If I do go ahead with replacing the calipers I may as well replace the steering rack boots (which I have), double check all the front suspension bits, and replace the rear lever shocks (which I have). So driving impressions from this up coming weekend will determine what I do next to the car....
