Let the brake master go empty, what now?

[Filthyoutage]

To make a long story short, I pulled my axles for a regear and in the process my brake lines were disconnected. Stupid mistake I know. And now my MC is empty. Can this damage the MC in any way? For reference I own a 97 non abs and the jeeps been sitting for a few weeks. Not sure how long the master has been empty for. Should I pull the master and bench bleed or just do a conventional bleed and see if the brakes feel spongy or not.

I would bleed the master and then the normal bleed process. I wouldn’t think you did any damage.

You should be fine. When I lifted my XJ, the rear brake hose was way too short and pulled loose before I got home. I drove 5 miles with NO brakes or fluid. All was fine when I bought a longer hose, flushed the system and added fluid.
p.s. @mrblaine could tell you with no guess work. He knows all.

Try the easier method first

Fill the master, buy a MityVac, and suck the air out of rhe lines from the master. You would be amazed how simple and effective they are

 

[Filthyoutage]

Appreciate all the reply’s legends. I’ll try the easiest option first, just bleeding it normally and go from there. Was just worried I might have cooked the mc. Not sure where I’d find a mighty vac in Aus, I’ll take a look on amazon or ebay

No Harbor Freight in Aus?

Call the Auto Parts stores if not

Master has to be pulled and bench bled. Use the plugged port method, not those stupid little hoses. For reference, next time, use a stick from the front of the seat to the brake pedal and push the pedal down slightly, that will stop the master from draining.

If that worked, we'd never have to bench bleed a master.

I wouldn't use another one of those pieces of shit if you paid me by the minute and gave me a truckload of them.

No harbour freight here, but after a quick search found it for about 80 bucks

How do you recommend going about it? Just a normal bleed to start?

I'm aware. I'm weary of bleeding brakes to fix problems that were caused by someone taking the advice to buy and use them. They'd have to get a whole bunch better to suck.

Nevermind just saw your comment

I already said you are going to have to pull the master and bench bleed it.

Awesome, cheers mate

My bad mate just read your reply the forum is bugging out on me

Its a good thing you werent asked to do it then

I bought one once...attempted to use it for an hour..proceeded to ask myself "self, why did you buy this piece of shit" and either tossed it in the trash or returned it I can't remember. I then proceeded to grab my wife who works for free and we bled the brakes together in a matter of minutes.

I think what escapes most about them is in order to pull a vacuum, the threads have to be sealed and there is no good way to seal straight threads good enough to hold a vacuum. If you could remove the bleed screw, thread in a port adapter with an o-ring to seal it, that could work but then it becomes stupid when you have to remove it to put the bleeder back in.

We have an actual plug in vacuum pump here for AC that we've rigged up to work on stuff to see if it helps solve common issues. It really doesn't. Pulling a vacuum on a steering system with a large reservoir and two lines so it doesn't just suck up the power steering fluid is pretty ineffective and just fucking messy.

I have one of the vacuum radiator fill systems. Works great until you get any liquid in the vacuum port, then it stops working.

So, we've played with vacuum more than most and it is pretty much useless for actual problem solving unless you are working on AC. We manual bleed brakes, drill bleed holes in thermostats, and manually cycle the steering and we have almost zero issues doing it that way. I need something that works, works every time and doesn't add to the problems.
