[abridged] Here we present the analysis of multifrequency data gathered forthe FRII radio galaxy PKS B1358-113, hosted in the brightest cluster galaxy ofAbell 1836. The galaxy harbors one of the most massive black holes known todate and our analysis of the optical data reveals that this black hole is onlyweakly active. Based on new Chandra and XMM-Newton X-ray observations andarchival radio data we derive the preferred range for the jet kineticluminosity $\sim (0.5-3) \times 10^{45}$ erg s$^{-1}$. This is above the valuesimplied by various scaling relations proposed for radio sources in galaxyclusters, being instead very close to the maximum jet power allowed for thegiven accretion rate. We constrain the radio source lifetime as $\sim 40-70$Myrs, and the total amount of deposited jet energy $\sim (2-8) \times10^{60}$\,ergs. The detailed analysis of the X-ray data provides indication forthe presence of a bow-shock driven by the expanding radio lobes into the Abell1836 cluster environment, with the corresponding Mach number $\sim 2-4$. This,together with the recently growing evidence that powerful FRII radio galaxiesmay not be uncommon in the centers of clusters at higher redshifts, supportsthe idea that jet-induced shock heating may indeed play an important role inshaping the properties of clusters, galaxy groups, and galaxies in formation.We speculate on a possible bias against detecting jet-driven shocks in poorerenvironments, resulting from an inefficient electron heating at the shockfront, combined with a relatively long electron-ion equilibration timescale.
