on my 04.5 I have noticed the drivers side fllor mat has a wet spot I finally had time to look at it. It seems the brake pedal shaft is slowly leaking power steering fluid?? I checked it it is red atf fluid that is in the power steering fluid tank? Anybody else have this problem or know of a fix??

 

on the old chevy,s the hydroboost leaked like that not sure but i think these trucks have a similar set up

 

Remember, there is no vacume on a turbo diesel, brakes get power off PS pump.

 

Im getting ready to buy a new ps pump for my 03. This will be my third one. Check the reservoir for cracks.

 

Sorry to butt in on your thread but the PS pump on my 03 is leaking but not much probably a tablespoon every 400 miles. Cameroneod--did yours start out this way? How much and where did you get your pump? Thanks

 

The leak is from the brake actuator rod going into the hydroboost unit. Don't think it's serviceable, the unit has to be replaced.

Yep...It's the hydroboost unit. Mine startred puking pluid all over the place at 6K miles. Needs to be replaced!

 

right now it is a slow leak onto the floor mat nothing under the truck any prices on the unit
