brakes HELP HELP

[chad reed]

anybody here good at brakes im  :cuss:at my brake system right now .ran all new lines from the master cylnder to the front and rear axle put in the proportioning valve etc .if i block off the front the rear brakes work .if i pinch the front lines i get peddle.im guessing it might be the front calipers but would they go bad from siting for 4-6 weeks ?the rears are they same and they did go bad .ive relaced and checked the master cynder and its good  any help or input   thanks guys

 I dont think they could go bad. Must just have a big air pocket somewhere. I have my friends power bleader but I never used it before..

did you bleed the master cyl
How worn are your front pads, sometimes you can get an air pocket in the caliper that wont bleed out. Compress the calipers with the bleeder open to make sure.

I know it sounds silly but check for seepage, you might have a pin hole leak? Ive had the tube split right at the flair just under the nut which allowed air in. Took for ever to figure out what was going on.

bleed the master,replaced and bleed it again  ,been thru all the lines 4 times no leaks  ,will try to compress the caliper trick  , pads are good thanks all for the help

Friend of mine had the same problem.. took 6 month of him try-n to figure it out.. I showed up and noticed that the bleeder was on the bottom of the caliper (on upside down) left was on the right side and visa versa..  hope it something simple

all these worked at tds and nothing was really changed but new lines   ill figure it out just need to take a break

check the booster    and also the vac line coming from the booster along with the checkvalve

what lines did you replace? i will bet it was the fronts. try to gravity bleed the lines and then re-bleed them with pressure make sure there is fluid in the lines and in the caliper.

i replaced all the lines after looking at it and reading a few things here and elsewhere i think the rears bleed off good cause the caliper and bleeder is at the top 12 o clock. the front calipers sit at about 2 o clock so i think there is air in the top of the caliper im going to try to rotate the caliper to the top and bleed it again. thanks for all the help i will let you know the outcome

Rule: Bleeder is always above the brakeline.. I believe you are correct in thinking there is air in the top of the caliper.. good luck
