Brake Booster Woes!?!?!

[FJ-KroozerKrusader]

l8ly my fj62 had been almost dying occasionally if i wouldnt press on the gas and keep it alive. well it only happened like 4 times so far. yesterday i was driving on some trails with a friend and it started doing it again( started to die but cranks immediately after it dies). once cranked it seems to not want to die again. so i left to go home, very close, and my brake pedal began to get stiff, i know some of the guys mentioned i prolly have a tear in the diaphragm in my booster. i just wanted to see if that sounds like it for sure........ also i dont want to shell out that much coin for a new booster if its something else. does this sound like the booster is making my car die from a leak in it? is it hard to replace a brake booster? me and my dad would prolly do it, any special tools required? and what gasket do i need to buy? or should i bring my car somewhere and get it done professionally since its ur braking system. please help if you guru's can-Cody

Check ALL vacuum hoses> Mike

one banana job. virtually anything toyota will fit be it supra, celica, 40/60/80 series, minitruck, etc. may require rod shortening at the pedal and adjustment of the pushrod. lots of threads and info in the 40/55 section. do an advanced search for 'booster' under my name on the 40/55 for plenty of good read

i have an update. i just went to the store to see how the braking system is, it worked perfectly, the pedal isnt stiff now , it has good pressure and is firm. it seems better than b4. can a booster slowly bite the dust? because i dont wanna get my hopes up but i know things like this can seem better for a while and then get worse just as fast. any help is still appreciated. suggestions.....

o by the way, i have zero vacuum leaks anywhere that i can find in the engine bay. i have quadruple checked. where would i check for the transfer case leak, i look up under there and i didnt see a hose of the vacuum sort

Howdy! I think there is a vacuum diaphram on top of the front output shaft. John

another progress report. i took a look at my manifold and sprayed with carb cleaner and found the culprit i believe. cracked brittle egr valve gasket. i am soo glad, do you guys think when the engine flexes it takes to much air in and wants to die maybe?

is the egr hard to take off to replace the gasket? does anybody know?
