    Does any member have any tips for removing and replacing Brake booster. I have 1970 SS 396. The original booster was painted silver before I bought the Camaro, and it has crude in the middle where master cylinder bolts to it. Back in 1991 when I had my 1970 SS 396 L-78 I removed and replaced it and I do not remember it being to hard. But when I checked the 4 bolts in the back of the booster it seems like it is impossible to reach them. Any help would be appreciated. Of course I will be keeping my original.

    Tip 1. Your don’t need to open any brake lines. Just unbolt the master cylinder from the booster and pull it forward.

    Tip 2. Booster can be removed with the hood and hinge in place but removing the hood and pushing the hinge down (tie it in place) gives you more room to work. (If your car is in pieces and the driver’s fender is off... Use this opportunity to R&R the booster.)

    Tip 3. Block out a half day on your calendar... The factory studs are often covered with undercoating and the nuts are self-locking. They come off very slowly due to access issues. (You will want to kick the engineer of this system so hard his mother will feel it.)
    Take your time and use a stubby wrench on the ones with the least access. You may be able to use a ratcheting box end wrench for part of the job.

    Tip 4. Put those self-locking nuts someplace other than on the booster studs in your car.
    Lock washers and regular nuts will hold the booster in place just fine.
    It makes assembly 10 times faster and the whole process is much easier if you ever need to replace it again.

    Good Luck!

    I ground down the sides of a cheap harbor freight ratchet wrench, made it a whole lot easier

    Offset ratchet wrench will be your friend.

    I do have a can of PB blaster. I will have to check to see if I have an offset ratchet wrench. Thanks EVILFACE and CorkyE.
