brake bleeding

[stizkidz]

I just replaced all my lines, hoses, and calipers going to the rear of my truck while doing my rear disc conversion. I am on the final step, which is bleeding, and I cannot get the brakes bled. Any tips or tricks to getting fluid to the rear calipers? They are stock chevy calipers as are the hoses. I have bled each side numerous times but still no fluid is getting to either caliper. Help!

try bleeding it at the t in the rear. pain in the ass, but see if you can get fluid there first. also try tapping a bit on the prop valve. did you bleed the master?

go pick up the 3.99 brake bleader bottle
best tool i ever bought.

just jam the hose into the bleeder, open the bleeder and pump till the bottle is full, then dump the bottle back into the reservior, and try to get all teh low spots outta the system

One more thing....make sure the bleeder screws are installed at the top of the caliper not the bottom or you'll never get all the air out

Those little mityvac things work great, and you could also try jacking up the front of the truck a little, then cracking the rear bleeders open and leave the truck alone for a while, just keep checking the resevoir.

When I've had that much trouble bleeding the brakes, it's always been a bad master cylinder.. sometimes the rod has a burr on it, which tears the diaphram, so there's never any pressure. damn rebuilds.

That's what I did too. Get the bottle with the magnet on it. It holds on to the fender so you can keep an eye on it and not overfill. Works great.

What I usually do is get a second person to pump the brake pedal, and hold it while I open the bleeder. I only do this a couple of times at each corner because it takes more pressure than gravity will provide to push fluid through the system and properly position all the pistons and cylinders in the right place for the first time. Then I use my cheap little $3.99 gravity bleeder to complete the job.
