Anyone know the diameter and length of an Fj-80 4 wheel disc power booster. What year did Fj-80's start coming from the factory with 4 wheel disc brakes?

I can measure mine tomorrow. 4wheel discs option in '93 and on.

Dave67cruiser,

If Eric doesn't post the dimensions, I will tonight. I remember trying to put one on my '75 cruiser though. The diameter is too big and hits the clutch master. If you are running an auto trans, the brake booster will bolt on nicely.

Approximately 9" in diameter and 4" long. You might need to add a 1/2" on the length to account for anything I couldn't see between the booster and the firewall <IMG SRC="smilies/smile.gif" border="0">.

Thanks for the replies. I'm not running an auto so your right the clutch master will interfear.
