Greasing brake caliper pins
When changing calipers and installing new brake pads do you put
some synthetic brake grease on the pin that holds the pads?
I ask this as I found that the corvette was pulling to one side when
braking. When I pulled the calipers and brake pads there was grease
on the brake pads. I did not notice any grease on the pin but the
last time I serviced the brakes I did put a liberal coating of synthetic
brake grease on the pin.
The only other thing I noticed are that the grease cups for the upper
ball joints on both sides have ruptured. Is it likely that excess grease
from the upper ball joints could have gotten on the brake pads on one
front brake caliper and not the other side?

I agree, no grease, maybe a slight dab of anti seize though and you either have a bad caliper or a rubber brake line that is deteriorating. I once had that problem on a friend's vette. But after replacing the caliper, the problem still existed. I found out that the rubber hose was detriorating and causing a restriction to the fluid flow. After replacing it with stainless braided lines, the problem went away.

In your example, I'd look at the passenger side for problems since the driver's side seems to be working.

But when doing a repair on brakes on the front, always do the same exact thing to both sides. That way, the uneveness will be prevented. You can buy a pair of calipers from Muskegon Brake here on the forum. They also sell the hoses.

I agree with Z-Man.
The car will pull to the good side. If the bad side has grease/oil on the pad or rotor, it will not brake. Therefore all of the braking action will be on the opposite side, and the car should pull in that direction.

Corvette pads don't move ( much ) they are not like late model single piston brakes where the whole caliper has to slide around.
If you have a sticky caliper it's probably something else.

Been doing 'em for over 30 years.... no grease on the pins. The pads only move a tiny bit, and the holes where the pins ride are way over-sized. No grease needed.
It will melt & run.
If you're bothered by the rust, you can get stainless pins.
