[iggys68dart]

a good friend of mine owns a mid 90s full sine 4x4 ram and he said it made a loud sound now he has no brakes pedal goes all the way to floor with minimal results he checked for leaks and no luck so he changed power booster still no luck any ideas thanks

Does he still have brake fluid in the resivor?

 

[iggys68dart]

yes he has not lost any fluid

 

[daredevil]

Not enough info. What kind of sound. Pop squeell hiss or bang?

 

[daredevil]

Isn't there a one way valve on late model boosters?

 

[iggys68dart]

he said it was more like a pop

 

[yellowdartdave]

Sounds like a bad master cylinder.

 

[iggys68dart]

we will give that a try today just looking for all angles thanks guys

 

[iggys68dart]

well we replaced master cylinder and booster still no luck or leaks any clue

if the truck has abs brakes or rear anti lock brakes only,most came with rear only anti lock, hydraulic valve could be bad.if this needs to be replace,if i remember correctly was have a scan tool to bleed valve.year of truck would help.
