Job not done right !!!
 
Switched out calipers on rearend of 2002 f250 and a couple brake lines. Bled lines several times. Still going to floor and spongy. I need help on this. What am I missing. Thanks

Takes alot to get all the air out...

A LOT.

Well I'll keep
On it I didn't get any air out of
Any of the four calipers. I'm guessing air lock. Thank you

Not tryin to be a smart alec but do you know how to bleed them :humm:

I believe I do. I've done the same thing in the past in on it. But maybe I'm missing something. Started with rear pass to the rear driver to front pass to front driver. Had someone pump up break peddle till it got firm while truck was off. Then I would open bleeder. Did this several times to every caliper and no air. Just fluid. Fill me in if I'm doing it wrong. Thanks

I think I did. Check out my tread and see if it's right.

No it sounds right, only thing I can think of is if you let the master cylinder run empty while replacing lines you might have to bench bleed it. I'd start with gravity bleeding first though. Start at passenger rear and just open the bleeder for 10 minutes keeping the master full, work your way around the truck doing that then go back around pumping them up and bleeding. :c:

So explain to me how to bench bleed. If this isn't correct. I'll make sure reservoir is full before I begin. I crack open the bleeder starting with passenger rear and leave it open and making sure the reservoir stays full. Doing each caliper for around 10 minutes. Is this correct??

No bench bleeding is bleeding the master cylinder with it off the truck. I've only ever had to do that when installing a new master cylinder. I just thought I'd mention that in case nothing else works. Try the gravity bleed first then the pump up and bleed again. I can't understand why if you changed the lines you havn't got any air out, you should have got lots of air. double check all connections to make sure you don't have a loose one sucking air in as soon as you let off the pedal. :c:

no bench bleed you need to take master cyc and bleed it by itself THEN do all calipers and lines BUT thats only if the reservoir ran dry...




yea what he said^ lol talk bout timing...
