Break Booster replacement

Remove the master cylinder, two bolts. Push it out of your way. Beware though. If the brake lines are really rusty, you may have to replace them also. Then under the dash there are four nuts to remove to get the booster loose. Go back under the hood and remove the vacuum line and pull the booster out.

There should be two or four mounting bolts accessed from under the dash. Usually the booster has studs and you remove the nuts.

Where is the computer located/

You have to disengage the PCM (computer) wiring harness from the PCM as the PCM is removed from under the dash. The PCM connector is located on the firewall under the hood to the left of the brake booster, you'll see the a large retangular wiring connector (120 wires) with a single bolt in the middle. Unscrew the bolt, go back under the dash to remove the PCM.

How to replace brake booster on a 92 honda accord

there are 4 bolts that hold it on behind the dash as well as a pin that holds the brake lever to the pin on the booster. You have to pull the master cylinder off, the brake booster vacume hose, then get the 4 bolts and pin out from under the dash. The 4 bolts are a rotay pain in the ***.

There is an air leak under the dash and it ties in with the brake pedal

It is a defective brake booster. When the internal diaphram of the brake booster develops cracks or pinholes from age, the crankcase vacume pulls air through the defective break booster diaphram from the air intake valve located on the rod connected to the brake peddle. At first the air leak sound my change or even go away when the brake peddle is depressed. But over time the booster diaphram will detierorieate to the point where the air leak sound will be contiuious. This is a problem that should be addressed ASAP as a defective break booster reduces the power assist to the break peddle and may make it difficult to apply enough break pressure to stop in an emergency situation.
Have the brakes checked by a certfied brake shop right away.

My car idles at 3 and the brake is stiff

Sounds like you have a major vacume leak, Chk. line going to break booster. Do you hear a loud hissing or whiseling noise either comming from under the hood or under the dash especily when you apply the break? If under dash could be bad break booster, if under hood still could be booster or a break in the vacume line from engine to booster.

Power Brake Booster has vacuum leak, How do I get the old one off to put the new one on myself? The shop says they will tell me for about $725.00, I laughed and said maybe later!

Remove the master cylinder. The booster usually bolts on from under the dash. Remove the four bolts and it will come off the firewall. Reverse to replace.
