how do I bleed brakes?

[airmanwilliams]

My help cancelled on me so I am going to try and do an axle swap tomarrow by myself but I dont know how to bleed the brakes. Im sure its simple but ive never done it. How do you bleed the rear brakes? Im putting in a samurai front axle with 5.12 gears and a rear hybrid housing with 5.12 gears.

If they're still spongy when you've done as well as you can, park w/the front tires on a curb, ramps, up a hill, whatever, and wedge a 2x4 or something between the brake pedal and the seat, cage, something. This will let any residual air get out.

It's the Ghetto Brake Bleeding Procedure, but it does work. Sometimes that last little bit is a real b***h to get out.

if anyone is willing to help me out in the swap I dont have much to offer but a rear 5.12 sidekick thirdmember or a warm meal and cocoa throughout the swap.

Gravity bleed....In the past when I swap axle's I just take the bleeder's out fill the res and wait or finish something else till they start dripping.I then put the bleeder's back in.Work's well enough to drive until I can get the wife to pump the pedal and even then there is hardly any air in the line's....work's quite well

What kind of warm meal are you talking?

The people want to know.

I can barbeque some pork ribs and make potatoes and corn.

Here's how I do it:
Find a time wife is willing to help (often time the biggest part of the job)
Get piece of tubing large enough to fit over bleed zerk and going to a small container (helps if container has a little fluid up to end of tubing this will show you as air is pushed through and also if the brake gets released before you tighten the zerk you suck fluid instead of air).
Have wife pump up the brakes and hold pedal down, you under vehicle turn zerk until brake fluid or air comes out when it stops flowing you tighten zerk and then have wife release the pedal and pump up brakes again, rinse, rather, repeat. Keep an eye on fluid levels on the master cylinder if it goes dry you start over. I usually will do each wheel for a few times after I see the last bubble just to make sure all the air is out.

Fluid color will usually show you where you are, a lot of times once the fluid starts to become clear it indicates the line has started pulling new fluid from your master cylinder. Make sure your wife knows to hold the pedal until you say release because when you open the zerk it will go straight to the floor.

My wife has done this probably 20 times over the years.

I start gravity feed as well, then go get her to help. She knows the routine, pump 3 times and hold, repeat, repeat, repeat... until a good solid pedal.

I always start at the furthest from the master and work my way closer.

If you get in a bind, let me know, Im nearby...

thanks chevy crew hopefully I can con someone into coming over to help me do the muscle work and help with the brakes but if I end up doing the muscleing myself and have trouble with the brakes I will send you a message.

... Just make sure the brake lines are attached before you crawl under there and someone starts pumping the brake pedal.

 

[Chevycrew]

Muscle work? Those axles are tiny, I just pulled the rockwells out of the crew alone.

What? That would be ridiculous....

napa has a part that is only $10 that allows you to do the brake bleeding by yourself... its a tub with a one way check valve... you put it on your bleeder screw after you open it a bit and then you just slowly pump your pedal until the air stops coming out... then you close the screw and move to the next...

during this whole process you need to keep filling your master cylinder with fluid... don't let it run out or you will be back to getting all the air out again...

here is the link to napa tool...

muscle work for me im a little weakling man but im going to go to autozone and get the brake stuff and try it myself I just hope this rain crap stops.

Those tubes work pretty good, but air can still get in around the threads on the bleeder screw when its open. I would still do a final bleed with a helper.
