New Calipers, rotors & lines = breeder valve leaking?

[1967ls2]

Just installed some new calipers, pads, rotors, and lines on my 67 camaro. There seems to be a persistent leak coming from both bleeder valves. I put rubber nipple covers on the valves but they still leak. Any suggestions?

Guessing you bought them at autozone or peep boyz ? I had a few bad ones from them , I had to rebuild or repair them after I bought them.
Did you try to install new bleaders? rubber nipples will not help, they are just dust covers.

Return/exchange the calipers if you can. The bleed screws seal against a tapered seat inside the caliper, so if either the bleeder screw or the caliper is corroded, pitted or otherwise damaged, you can get a leak. If it's the seal on the caliper body, nothing short of remachining that surface will fix it. Alternatively, you may just have calipers with the wrong bleeder screws, causing them to bottom out on their threads or something similar before making hard contact with the sealing surface.

I purchased the calipers in a disc brake conversion kit which came with rotors, pads, calipers, bearings, dust caps, etc. The bleeders were pre installed. I just went to the auto parts store, picked up some speed bleeders and installed. Pumped the brakes a few times and didn't see any fluid seeping. Will check again tomorrow after work to see if it's leaking our not.

When I pulled the pre installed bleeders out I could see where the bottom of the bleeders were making contact with the caliper seat and it looked like the wear mark wasn't making full contact.

Thanks for the response!
