Brakes gone after backfire!?
Hey Guys,
Need some serious help here, maybe I am missing something.
Drove the jeep this morning to work, tried to go to lunch and the jeep had a hard time starting, it didn't turn over the first try.
Tried it again and it started but I heard a loud POP under the hood and it looks like it backfired in the intake manifold and blew off the LDP hose from the manifold so I put it back on and now i have no brakes at all.
I checked the hoses but maybe I am missing one?
The brake pedal is stiff as can be and will not move at all, am I missing another hose that possibly popped off? Has anyone heard of a backfire in the intake blowing the brake booster?
Thanks!

I have never heard of a backfire blowing the brake booster. But you may want to check the check valve that is on the brake booster that is connected to the hose to the manifold. I have had the check valve blow out and the brake peddle did get hard to push.

Thanks I will check that, that is the piece connected into the brake booster correct?
Does that just pull out with some force? I do not want to break anything.

it just pulls out but the little plastic piece is a one way valve you might have broke the inside of the check valve just something to think about

Thanks guy you were a big help
After looking closer at it, it had actually blew the entire top off of the check valve!
Thanks again!
