i know several good DIY guys that open one bleeder screw at a time amd wait until they get a solid flow of brake fluid out of it and then do the next one, I was taught when bleeding brakes with the older single piston master cylinders to start bleeding at the right rear and then do the left rear, then move up to the right front and then finish at the L.F. the one closest wheel cylinder to the master cylinder I do the same way on the new dual piston M.C., bleed the farthest one first and then do the closet one to the MC, front or rear first doesn't matter to me

i know several good DIY guys that open one bleeder screw at a time amd wait until they get a solid flow of brake fluid out of it and then do the next one, My one-person method is to put a piece of vac hose over the bleeder screw, stick the other end of the hose in a partially filled jar of brake fluid so the end of the hose is submerged. Then open the bleeder and pump the brakes until there are no bubbles coming out into the jar. The only trick to it is getting in a position where you can see the jar and pump the pedal at the same time. I have never heard of anyone starting the car to bleed the brakes.

I am really embarrassed to ask such a basic question after owning my Mopar for over 50 years, but here it is: my 69 roadrunner has had a brake failure due to a bad master cylinder; now it has been rebuilt, but I need to bleed the whole system. The car has power brakes, and the question is: does the engine have to be on while bleeding each wheel or can I do it with the engine off? Thank you. Before you go any further with the bleeding of the system, seeing that the master has been rebuilt/replaced, best to check the air gap between the booster's rod and the bore of the new master, even if it's the original unit rebuilt, dimensions can change, too large an air gap, the pedal will always be on the floor, too tight or no gap will result in the front calipers dragging....Mopars generally are good with .060 air gap.....and can we assume you have/plan to bench bleed the master before install? Here's some pics to understand the "air gap"...

Let off the throttle all the way and downshift into 2nd gear and get ready to use the emergency brake when needed to complete the stop. 'I'm glad you and the car were not hurt or injured: up: I went through a 6 ft. tall chain link fence at work when my old 1963 Plymouth M.W. car throttle stuck at WOT while goofing around driving it into our work yard one morning due to the left rear wheel cylinder failing when I jump on the brakes hard to try and stop it. I'm glad that didn't tear the car up more than it did, it tore the 426 hood emblem off and scratched the front of the hood and roof above the windshield, not good. That incident scared the keck out of me and made me think a lot more after that before doing stupid things in a car with some power work:

My brake failure story:
Out in our storage yard in Phoenix, AZ., I was tasked with airing-up the tires on a '65 GTO & moving the car. I started it & backed it out of the slot - it was obviously hard to roll because all 4 tires were flat, but it felt like it had brake pedal pressure. I aired the tires, started it & it was on a high idle, I put it in gear (automatic), & forward I went kind of quickly - I went for the brakes & nothing - NO BRAKES at all! I had about 50' to make a decision on what to do - either plow into a beautiful 1975 Roadrunner I had purchased at a used car lot (with 35,000 original miles I might add), or take the GTO out the gate & into a busy road - Broadway. I took the GTO into the Roadrunner to stop it & I let out a helluva yell as I hit it. I didn't even have time to think about hitting the emergency brake or jam it into park - it happened so fast. I tried to pump-up the brakes but the system had to be empty. I was SO pissed! I stove-in the RR quarter panel behind the wheel about 10", but the GTO came to a rest. I feel the sickening feeling every time I think about it!
