Okay so my pedal would go down to floor and so I bled my brakes correctly and helped but then over like an hour it would go to floor again. So I put a new booster and master in but forgot to bench bleed so it had almost no brakes, so I took it off returned and got a new one, then bench bled it correctly and helped, but it still wants to go about half way down before giving me stopping power, no leaks, and solid stream of fluid out of bleeders. Could there be air in the abs pump? When my truck is off it can hold good pressure and feel great but as soon as I start the truck there pretty crappy. Any ideas what's heppening?

 

Possibly a bad abs valve assembly or the module it self. Its very common.

 

My truck has been doing this ever since I got it. Everyone thinks my brakes suck but it's only because they engage so late in the pedal stride. I remember when I was researching the subject I saw that many guys adjusted the nut behind there master cyl. This gave them the pressure they wanted. I haven't done it myself to check to see if it works but I would try it. All you do from what I read is you take off the MC and the but is behind it. Not sure which way you have to go tho

 

I have the same problem but I buy front and rear caliper and also buy a used abs pump an still do same thing when my truck is off it can hold good pressure and feel great but as soon as I start the truck there star the problem again

 

Bring it in.

 

yeah I have to clue what this problem could be :/

 

I wonder if yalls brake lines are ballooning

 

Me too, but I don't think that's the problem

 

I will take it to real brake specialist I hope he can resolve the problem

 

Keep us updated and let us know if it's get fixed and what was wrong
