if your fluid becomes contaminated usually from someone putting power steering fluid in the master.
IM THANKFULL I'M STILL YOUNG ENOUGH ( 72 ) TO DO MY OWN WORK AND DO REASONABLY TO TROUBLE SHOOT MY PROBLEMS.
[email protected] GMC Z71, going through this issue now!!!
another $500, but won't charge me the diagnosis fee, only the part and labor. So have any of you pulled the master cylinder and find the booster is hull of fluid because I'll bet that is the problem.
At this point the fluid has ruined the booster so now you have to replace both.
I', NOT A VERY SMART PERSON BUT MY LONG SHOT THEORY WAS ALL THAT WAS LEFT. I KNOW A JOB LIKE THAT ISN'T A MECHANIC'S FAVORITE THIN TO DO.
