i need to do an emergency brake swap tonight
So tonight I was heading down to ft lauderdale from my house in west palm beach, fl in my 1996 200sx se-r and long story short, I was going 80mph and started hearing a noise somewhat like an exhaust leak and a few seconds later I lost all power and white smoke started pouring out from under the hood I quick pulled over (5 lanes of rush hour traffic coasting) not fun but I grabbed my fire extinguisher thinking it was a fire, jumped out and find the top radiator hose blew off and nothing was left in the radiator (gague in dash stayed normal temp the whole time) so I let it cool a little to get the steam to clean and it kinda melted the rad outlet, I took off the oil cap and it smelled just like what was in the radiator but oil is at the same level, I tried to crank it over and it turns like the spark plugs are out and doesent catch or run, so now I need to get my 1.6 on the road but the rear beam and drums are all rusted and everything is leaking, I have a rear beam for disc sitting in my garage if I just swap that beam in tonight how bad would the brakes be if I don't swap in a master cylinder for now, would I be able to stop or would it be worse than the leaking drums
