i went bigger with my lift so i put extended brake lines on . then bleed and bleed and bleed them and still got soft peddle replace the master and booster and bleed again no leaks all lines are looking good everytime i bleed them . when my jeep is off the pedal is nice and firm but when i turn the jeep on the pedal goes does down to the floor and has no pressure and cant think of what it could be anythoughts

 

Did you change anything other than add longer hoses? (Before trying a booster and master cyl.)

 

Just brake lines . And just tested the vacuum booster while the jeep was running unplugged it and got good firm brake pedal plugged the line back in and pedal went to the floor

 

bleeders on bottom of caliper ?

 

Yup bleeders on the bottom should I swap them and put them up top

 

Bingo air goes up...your not the first bad design flaw...

 

Love the picture by the way

 

Google is our friend ....lol...

 

Gotta switch sides caliper wise ..just so ya remember...

 

Now that ive switched the calipers would I be able to bleed just the front or should i re do the whole system

 

Just the front will do.

 

just the fronts would work. but what would it hurt to bleed it all over. brakes arent something you want to go down the road with out

 

I here yea on that thats why its sat in my drive way and been working on it for last couple of months its been neglected. Also to add to I'm getting better peddle response from swapping haven't got to bleed them yet waiting on a buddy to get over here and then ill probably now if my knew brake booster is really bad or if it was just the calipers which is weird cause they've been upside down for quit sometime and had pressure thats just weird

 

After bleeding air out as long as systems not opened don't matter were bleeder is. But lets leave them on the correct way. Brake lines are not twisted right, now that calipers turned around ?

 

Yea calipers are on right this time air is bleed out still a little slow on the return but they do stop probably going to bleed the whole system again or adjust the rod from the vacuum to the master see if that doesnt fix that
