  • brake booster upgrade

    If I upgrade my brake booster to a 83' and newer model do I install my original master cylinder ( 81' ) or do I have to go with the 83' to 91' master? Thanks, OLY

    I answered the question, I didn't realize the 81' master cylinder was the newer model, but let me ask this, I found a used brake booster for $60, (83'-91') how can I tell if it's good? Thanks,oly

      Personally, I don't use used brake parts. Not worth the risk. But if you are on a tight budget, you test the brake booster with a vacuum pump. Preferably one with a gauge. Make sure it doesn't leak down. Then press in on the rod and make sure that it doesn't leak. The vacuum level will change when you press it, but it should not go to zero.

        Thanks Stuka, I here you about the safety issue, the booster is from a 4x4 yard (local) and I planned on asking them if they tested it and if they can stand behind what their selling. Very good point taken OLY
