Vacuum hose missing from brake booster

The brakes became very hard to push pedal and when I looked under the hood a vaccum hose was missing from the brake booster.

    Paul Oglesby Nov 29, 2012 It came off the booster and I can't find it or where it goes to. There are two hoses that connect to a tee on front of the booster. the one facing the passenger side is there, the one coming straight out is missing completely I don't know where it went or where it connects on the other end? Paul Oglesby Dec 01, 2012 Found the problem, a cap fell off the other port. There is only one hose connected to the brake booster apparently. When I moved the car, the next morning, there was a rubber cap lying on the ground. So I put it on and all works fine. I just couldn't find any diagram that showed the vacuum line connections/routing and assumed that a hose connected there, not a cap/plug.

check 2 things first one is their is a plastic check valve that is inserted into the booster (under your hood) then goes to a vaccum line ,then to the engine, pull it out of the booster and check the valve it should be L - shaped. it might have a hole in it causing a vaccum leak. be carefull pulling it out not to break it just pull straight out. if that is ok put it back in. then your problem is going to be the brake booster the big black round case. sometimes the diaphram inside the booster rips causing a vaccum leak which causes a hard brake pedal and you have to stand on the pedal to stop. then you will have to repace the whole thing but not the master cylnder unbolt master cylder with the brake lines connected, the lines will give then disconnect brake pedal arm under dash inside of trk their should be 2 nuts or 4 buts under dash on inside of firewall near brake pedal then remove booster pulls out from under hood. there is not much to replacing them.

SOURCE: Slight air hiss or sucking sound near brake pedal and no

It maybe, I don`t know the vehicle personally but on Trucks and Buses, when this occurs, it usually points to the master cylinder piston seals which moves in and out as the foot pedal is operated. Does the hiss alter as the pedal is pushed down?? Does the hiss reduce or increase as the pedal is pushed down?? If it does, I think you`ll find that it`s this air seal between the piston and cylinder that`s failing and not the servo. Whether you car works the same way, I don`t know but I presume it must. Ian

Why should it. All the vacuum does it make it easy to push the brake. That's why it called power brakes.

look under the hood and check the brake booster. this is the part behind the master cylinder where you would put the brake fluid. on the brake booster there should be a large vaccum hose make sure this is hooked up and the other end is hooked up. ......your peadle is so hard because the brake booster is'nt getting any vuccum.

Brakes are hard to push down to stop?


Hi- Check your large - very large black hose that goes to the Power steering booster. The booster sits right in front of the driver under the hood and is black - round and large. It has a hose that goes to it from the intake area of the truck - this hose has to be - in good shape - capable of holding a vacuum and attached at BOTH ENDS.

Replace if necessary.
This should fix your problem

please vote me 4 hands up of this is a fix for you.

Thanks
