I just put on rebuilt front calipers from Volvo and then did a pressure bleed of the fluid at all 4 caipers. I cleaned off any spill and then pumped the brake pedal and held it under pressure several times. All looked well and dry.

When I came back a few minutes later, each front caliper bleed screw had weeped a drop of fluid onto the caliper. I cleaned it off, pumped and held the brakes and the same thing. Dry but later a drop weeped out.

Neither caliper bleed screw was removed. Each is very tight. I don't want to tighten them any more for fear of stripping the threads.

Any suggestions?

My only thoughts are either both are defective, which seems unlikely, or both got a piece of grit between the mating surfaces during the bleed.

Any help you can provide would be greatly appreciated.

Thanks.
