The brake booster works by vacuum through a hose connected to the intake manifold. If the hose is disconnected or damaged, you would hear a sucking sound. Replace or reconnect the hose. If you need to replace the power booster, its bolted through the firewall with four studs. Remove the nuts and it should come right out.

How to remove brake booster on 1999 mercury sable gs

Remove the master, two bolts. Move it out of the way some what. Be careful of the brake lines. Under the dash on the fire wall, at the brake pedal, there are four nuts to remove. Also remove the linkage on the brake pedal. Pull out the booster and replace.

Breaks are hard to push and I hear air from under the dash, and Master Cylinder fluid is very dark. How do fix these problems?

sounds like you need to replace the brake booster, and flush the entire system. the noise you hear is air leaking out of the booster. hope this helps. good luck.

How do I remove the brake power booster from a '97 Thunderbird? I'm getting a hissing sound and can feel air under the dash when I press on the brake pedal. All of the bolts, clips, master cylinder, etc...

Remove the rod going to the brake pedal,then remove the master cylinder,you may can unbolt the master,from the booster,and move it out of the way without removing the brake lines,they will give quit a bit.Now go back inside and remove the four nuts on the studs holding the brake booster in,they may be a little hard to reach,and of course remove the check valve with the hose on it,going to the booster under the hood,If this was at all helpful,please rate,thank you.

When i step on the brakes the engine idles fast, I think I need to replace my pb booster, is it a tough job?

it should when you push the brake pedal but only for a second or 2. if idles up and stays up then yes its bad, start,push pedal, and put ear under dash and you should hear it **** air. its not too bad, unbolt the master cylinder, has braided steel lines going to abs modulator, flop forward outa the way. undo vacume hose, then go under dash, take out rod to pedal pin, 4 nuts, and pull it out of the firewall. you do not need to bleed brakes if you do not undo a hydraulic line and be delicate with brake light switch on the pedal

Brake pedal hard to push, like the power is gone. would this be power booster or master cylinder how hard is this to change out?

Could be booster, chk. vacume from engine to booster, usely when that happends you have lost vacume to the booster, very seldom does the booster go out, I'am not saying they don't, its just seldom they do. Do you hear a hissing sound either from under the hood or under the dash above break peddel? If you do you got a major vacume leak,if you hear it comming from under the dash its the booster, if you just hear it under the hood its in the vacume line from engine to booster.
