1983 300 Brake Parts

[Waipio Rim]

"How did you determine that you needed to replace the master cylinder AND the hydroboost?"

Mechanic said it needed a m/c for sure, and recommended replacing the hydroboost just in case. Having just gone through the fun of calling for a tow truck while blocking a lane of traffic, I took the recommendation.

Ours has a big bottle jack in one of the storage drawers, but I have not used it yet. I guess you could use the levelers to get it up in the air but I would get it on jack stands before working on it, I have heard of these beasts rolling off of the levelers.

BTW I couldn't find a jack. Do I just use the levelers?

Do not use the levelers, especially the folding kind. You will lift the body way up before you lift the wheels and once you lift a wheel you have no parking brake.

Chock the front wheels front and back and use a bottle jack under the axle spring pad. You only have to lift a little to get the tire off the ground and the body stays almost level. Don't lift the tire any more than to see air under it. The higher you go the higher you have to lift the tire off and back on. It's not really difficult work but the parts are heavy so take your time and think ahead as you work. You don't want to play with the heavy stuff more than you have to.
