We discuss the results and implications from deep Chandra and multicolor HST observations of two jets hosted by the powerful quasars 1136--135 and 1150+497, together with new radio observations. The sources were selected from our previous X-ray/optical jet survey for detailed follow up aimed at obtaining better constraints on the jet multiwavelength morphology and X-ray and optical spectra of individual knots, and to test emission models. In 1150+497 the X-ray, optical, and radio profiles decrease in similar ways with distance from the core up to ~ 7\arcsec, after which the radio emission increases more than the X-ray one. In 1136--135, downstream of the most prominent knot at ~ 6.5\arcsec\ from the core the X-ray emission fades while the radio emission brightens. The X-ray spectrum also varies, with the X-ray photon index flattening from \Gammax ~2 in the inner part to \Gammax ~1.7 to the end of the jet. We intepret the jet behavior in 1136--135 in a scenario where the relativistic flow suffers systematic deceleration along the jet, and briefly discuss the major consequences of this scenario.
