Removing 301 redirect from 2.5 yr old domain

[Modi]

Hello, Need Advise. We are in Automobiles

• We have an Automotive site - build 3 yrs back - which is our main site (Site A)

• We built a separate niche site on Used cars 2.5 yrs back (Site B - url http://www.usedcarindelhi.com) - did seo - promote it for a year and later on in feb 2013 - did 301 domain redirection to Site A

Now - we thinking to rebuild Site Site B again and remove redirection

• Will there be any harm on Site A, as we have now removed the redirection or shall we pass on link from home page of Site B to Site A i.e say Powered by Site A (on Top) or at all no direct linking is actually needed.

PS :- Also - can anyone let know the backlink quality of www.usedcarindelhi.com. Its PR 3, DA - 18, Majestic Citation Flow - 18, Trust Flow - 11 .

Pl advise

If you remove the redirection, you remove the link juice from any links to site B that was flowing to site A.  Having a link or two from B to A won't likely provide near the link juice of the redirects (I see 10 domains linking to site B today).

Still, we're only talking about the link juice from 10 domains, so it's not a huge deal.
