Where can you find the 'brake booster line' on a 1996 GMC Sierra?
The Brake Booster is mounted on the firewall and the master cylinder is mounted on the booster. Look at the booster and you will see a very large vacuum line coming from the booster.
How do you diagnose a very hard pedal when applying the brakes of a vehicle equipped with a hyrdo-booster?
You are taking too much vacuum away from the vacuum booster in the brake system. Try to find a smaller vacuum hose somewhere else in the engine to use for the Hydro Booster. The boost line for the brakes comes from the primary vacuum port on the intake manifold. Use a secondary vacuum source. That vacuum for the brakes needs to be undisturbed for correct operation of the braking system and the ABS if so equipped.
How do you replace brake master cylinder an power booster on a 1993 chevy cavalier?
Remove brake lines from master cylinder. Remove the two bolts attaching master cylinder to vacuum booster. remove vacuum hose from vacuum booster. It just pulls out of booster but will give you a little resistence. Remove cover above gas and brake pedals on drivers side floor board. While laying on your back or right arm look up into dash and find and disconnect brake pedal linkage/rod from brake pedal (there is usually a pin with a clip holding this together). Then remove 4 bolts attaching vacuum booster to fire wall. Go back under hood and remove vacuum booster.

What is needed to convert a hydroboost brake system to a vacuum power boost system on a 1988 Lincoln Mark VII?
Remove the hydroboost unit from the firewall and replace it with the vacuum assisted booster. If you are careful you may be able to do this without disconnecting the brake lines. You will need new powersteering lines and find a vacuum source for the new booster.
Need vacuum hose diagram for 1973 Dodge Charger Carter Thermoquad carburetor?
It might have four hoses? Pcv and Brake booster go to separate large ports, the pcv usually to the carb base and the booster to the manifold fitting. Vacuum advance goes to one of two small ports on the carb. Test to find the one that has no vac at idle but as soon as you touch the throttle you get vacuum. Cruise goes to either the small port on the intake or the carb base. It could be split off the vacuum advance.

Generally when a booster goes out, you have to use your full leg to push the brake pedal down. It becomes very stiff.

On a car this old where you suspect a vacuum leak, the best thing to do is just replace all vacuum hoses under the hood. Cheap repair, and you can bet on a 18 year old car, they all need replacing. Warning: Replace them one at a time as to not get confused. Also replace the large vacuum brake booster hose, and make sure the brake booster is not busted.On a car this old where you suspect a vacuum leak, the best thing to do is just replace all vacuum hoses under the hood.
