Removing Brake Booster 1986 F150 5.0
I replaced the master cylinder on my 1986 F150 regular cap 5.0 last weekend. After bleeding the brakes RR, LR, RF, LF I took it for a test drive and the pedal sounds like it is bleeding air. Everything that I can find indicates that the booster is bad (vacuum line is pulling a strong vacuum when running). I removed the master cylinder from the booster, removed the 4 nuts inside the cab holding the booster to the firewall, disconnected the booster from the cable and the brake pedal. When I tried to lift out the booster it wouldn't budge. Acts like there is something else holding it to the firewall but I can't see anything. The Haynes manual doesn't show anything. What am I missing? I tried to pry it loose, put nuts back on the booster bolts and tapped it with a hammer after placing a block on the bolts. I'm open to suggestions! This looks like a straightforward job and it is whoopin my behind.

It's a Canadian thing eh!
Its just stuck to the firewall very good from the gasket, basically glued. I had the same problem a month ago on a parts truck and used a pry bar to get it free.

I thought that it might be glued but I was afraid to pry on it because I didn't want to dent the firewall (when I grab the booster I can shake the truck!) I'll give the pry bar a try. Thanks

Once you get the bolts off, just go to each side and work it loose with the pry bar. Firewall will flex a bit but it does come off as long as its all unhooked.
