Brake Booster
Hello to all, I'm having a small problem with my brakes on my 2wd 85 F-150 with a 302 automatic. Basically when i hit the pedal it goes to the floor with no resistance until about an inch from the floorboard. When I don't have my foot on the pedal there is an air leak from around where the rod goes through the firewall. After all the searching I have done, it appears that I have a faulty brake booster, and I would like some input before I spend the $150ish on a new one with a new master cylinder as well. Just to throw another thought out there, could a master cylinder rebuild kit possibly fix this problem?
Thanks in advance,
Michael

I have to same problem with my F250.I called Oreillys for another power brake booster with a master cylinder.Mine leaks between the booster and mc and what I have been told the diaphragm ruptured.O'Reilly Auto Parts qouted a price $109.99 that was the cheapest I could find.

Thanks for the welcome, I've acually been around here for about 3-4 years now from the early days when I had my old 79 F-250 4x4 supercab. I just got my 85 about 3 months ago with 94,xxx miles on it for $1000 from the original owner. Anyway, I acually know how to use the search function so I don't repost the same thing as someone else, but this one stumped me a little and being military I try not to spend more money than I have to seeing I don't get that much anyway. Buy the way, we don't have an O'rieleys around here that I know of do they have a website you can order from that you know of? Shipping would probibly bring the cost up to about the same in the end though.

Don't know if they have online shopping yet, but their website is www.oreillyauto.com it can help locate parts and also store locations.
Hope you enjoy your truck and thanks for protecting the country.

I also have a leaky m/c; between the m/c and the booster.
This is going to be my third m/c-booster combo for my 81 F150.
Time to get a little dirty.

Thanks for the info, but i just picked up the one with-out the m/c so I don't have to fiddle withe the brake fluid at all. I also picked up the upper and lower ball joints, rear wheel bearings/seals and a center drag link. I have alot of fun ahead of me if it will ever stop raining here in Virginia.
