2005 GMC Yukon XL Denali Question: leaking power steering between the master brake & brake power booster ?

what do i need to change to fix that leak and how much can cost me that. -
Answer 1
is your pedal spongy if so you probably need a master cyl -
Comment 1
CORRECTION...a spongy brake pedal does NOT mean a bad master cylinder...a LOW or SINKING pedal are signs the master cylinder is failing. . . And leaking POWER STEERING fluid will NEVER cause a master cylinder to fail! -
Comment 2
when my hydro booster ran out of power steering fluid my break started to failhey vehicle with hydro booster has a ride to actuatesyour breakmaster cylinder I do not know which one is going outso I believe that the booster does affect your master cylinder -
Answer 2
if your leaking p/s fluid it must be a hydraboost system. poss hydraboost rear seals are bad -
