Question: I am bleeding the brakes on the Charger,,,and not sure it is going right. I have a Mityvac (see pic below),,,i have used it before without too much problem. I seem to be seeing ALOT of bubbles in the plastic tubing lines when i try and bleed the system. I am having a hard time telling if it is working or not ? I am wondering if some of the problem could be with the bleeder screw allowing air around the threads where it screws into the wheel cylinder ?? The bleeder screw does get a bit "wobbly" after i loosen it up to bleed them,, Dumb question ...but how "loose" should that bleeder screw be ? enough to see a small drip,,stream,,? I am going to try and find the manual for the Mityvac thing i have and see if it has a trouble shooting guide........ thanks for any advice... Doug

that's too loose , you are pulling air back in if it's wobbly. You want ~1/8-1/4 turn

I have heard....HEARD.....that if you are doing it by yourself and you aren't in a rush, you can raise the front end and crack the bleeder screws loose and leave it there for 2-3 days and the air bubbles naturally rise to the highest point in the line (the bleeder screw). tighten em down and raise the rear and let that naturally get rid of the bubbles, crank the bleeders shut and your brakes should be good.
Again, I have never done this, only heard of it

OK let me get this straight because I may try it. Alone with plenty of time. Jack up front, crack screws, leave 2-3 days, tighten and lower. Then do the same for the rear end??

Thats just what I have heard....There is a pneumatic bleeder that a friend of mine used to have and it was awesome. You hook it up like normal, crack the screw loose, and pull the trigger. It had a half gallon jug under neath and it would suck the entire line into the jug. Keep refilling the master and keep doing each corner. He showed me the first time and he was done with the bleeding in 15 minutes for the entire car. Here is one on the E-bag

I use the Vacula bleeding system and it does the job.If the bleed screws are too loose you will see a lot of air bubbles.

Also I put a block of wood under the brake pedal so my helper doesn't push it(the pistons) past their normal length of travel into an unworn section of the bore.

Just run a tube from the bleeder screw to a mason jar half full of brake fluid. Open the screw and pump the brakes slowly and do not let the reservoir run dry. Pumping will pump the air out and the tube stuck in the fluid will act as a check valve so nothing comes back in the lines.
It's the preferred method for us people that don't have any friends.
but gravity bleeding also works (ie crack open the bleeder and let it drip for a few hours). the main concern is to make sure the master cylinder doesnt run dry or you have to bleed that and start all over again

These work really good if you are bleeding by yourself. I have them on two cars.
As mentioned, when bleeding, you only need the bleeder screw open just enough to get fluid and air out. Wobbly is too much.
I always insert the bleed hose into a jar with some brake fluid. With no speed bleeders, it will help prevent sucking air back in.

I use this pressure bleeder,It holds 1 gallon of brake fluid. Top part holds fluid with a rubber diaphan separating the lower half which is pressurized with about 20-30 psi of air. I just recently took it apart and repainted the top half after 20+ years of using it. The diapham inside was in great shape. I have master cyl adaptors for about 6 different master clys including the plastic resovour master clys. I recently replaced wheel clys on a boat trailer and I have a round multi thread cap that threads into the master cly up on the tonque of the trailer on surge brakes.I bled those new wheel clys in about 10 seconds per side and I was done. That's when I decided to clean it up after that job. Anyway it a failsafe way of doing it and it only takes a few minutes to hook it up. The cap adaptor shown is for cast iron dual master cyls like we use on our old mopars. My other mc adaptors are at work.It's great for flushing brake systems too. I store it with fluid in it pressurized with maybe 10 PSI. There's no air to get in there and spoil the brake fluid. So a gallon last me many jobs. [image]http://[/image]

do it exactly like his way.save your money on those bleeders. start from farthest rear tire and then to next rear bleeder valve but keep adding fluid to your master cylinder,dont let it run dry. its also great to do this to remove any old nasty contaminated brake fluid.

I have a little different version of this. I use a mason jar and use 2 tubes. One goes to a vacuum source (engine port usually). The other to the bleeder. Make sure the vacuum line is really long ( so you can reach any wheel ) and is just barely in the jar so you don't suck any brake fluid into the engine. Seal where the tubes go into the jar lid with silicon. Start the engine and crack the bleeder on the wheel and let the vacuum suck the fluid into the jar. Has worked for me for years.
