Hello fellas, my brake pedal goes all the way to the floor and there is brake fluid leakage around the master cylinder where it bolts on to the power booster. This truck was sitting for a couple years and the power booster/master cylinder is real rusty so i am going to replace both. I have a question: are there any special instructions i need to know about when replacing the power booster? I have changed the master cylinder before but not the booster so I was wondering if one of you would kinda give me a short list of what not to do and what to do's....Thank you... My truck is an 85 F150 351w two wheel drive automatic transmission with cruise control...
