I can't believe I'm the only one out there that has had this issue....Any ideas from anyone?

 

Does your pedal have the same feel as it did before? Did you try to bleed the front brakes? Any codes your throwing?

 

Crack the bleed screw and press the brake pedal. See if you're squirting fluid. If you are, you know your master cylinder and lines are good. If your pistons aren't moving, perhaps when you pushed them back into the caliper they are now seized or cocked sideways in there. If you have a high enough pressure air compressor, you can remove the bleeder screw and blow air in there to hopefully push the pistons out. Put a piece of wood or something else in the caliper to catch the pistons so you don't shoot them all the way out of the caliper.

If you aren't getting fluid out of the caliper, you could have some crud or something else blocking the lines from pushing fluid back up. Keep moving up the lines to check if you are getting any fluid pressure when hitting the brake pedal. You may just need a brake fluid flush.

 

Awesome guys, I'm gonna check to see if I'm getting fluid tonight, I never bothered trying that because I never cracked the system open.

So what happened?

 

Ok, so I had the wife get in the truck pump the brakes and hold them down, I get a dribble of fluid out the bleeder no squirt, just a dribble....Bad master cylinder? thoughts?

 

Did you twist the flex hoses when you put the calipers back on?

 

nope...double, triple checked that today....

 

Crack a bleeder screw at the master and see if it squirts. Then you know if it's a bad master cylinder or you have a restriction in between the caliper and master.

 

Try cracking the line at the caliper and see if you get more than a dribble. If you don't get more than a dribble crack the line at the master cylinder and check again. If you get good pressure I would bet the hoses to the calipers are bad. If not you probably have a master cylinder problem.

 

got a little fluid when I cracked the front connection to the caliper (closest to the front of the truck) when i cracked the rear connection to the caliper I go nothing (closest to the cab of the truck)

So, my guess is the master cylinder, can someone please agree with me or give me better guidance...(sorry, I'm so pathetic, but i'm slowly losing my confidence with this) UGH!

 

If you had someone putting pressure on the brake peddle while you did this and there was brake fluid in the master cylinder. I would say you have a problem with the master cylinder. Might try bleeding the master cylinder first to see if it will pressurize. If it wont it probably needs a rebuild or replacement.

 

turned out to be the master cylinder was bad. swapped it out bled the brakes and TADA...I can stop! I love it when I can stop!!!
