Today I replaced the rear left brake caliper and when I tried to bleed it there was little to no pressure. Tried bleed the right side and had no problems just very little pressure on the left side. Can anybody help? Thanx.

 

vdub, from the sounds of things, you need to pump more fluid through the caliper as you were still filling the caliper. The other possibility is that you did not have the bleed port open enough and that was acting more like a restriction than a bleed port. I would say to give it another try and make sure that you can get the bleed port open a full turn before bleeding and that you are getting lots of fluid out of the caliper.
