It is known that the Einstein field equations in five dimensions admit more general spherically symmetric black holes on the brane than four-dimensional general relativity .
We propose two families of analytic solutions ( with g _ { tt } \not = - g _ { rr } ^ { -1 } ) , parameterized by the ADM mass and the PPN parameter \beta , which reduce to Schwarzschild for \beta = 1 .
Agreement with observations requires | \beta - 1 | \sim| \eta| \ll 1 .
The sign of \eta plays a key role in the global causal structure , separating metrics which behave like Schwarzschild ( \eta < 0 ) from those similar to Reissner-Nordström ( \eta > 0 ) .
In the latter case , we find a family of black hole space-times completely regular .
