if you are upgrading to anything 15/16 or less you could probably skip the booster upgrade, unless the new mc has a different mounting position. some of them bolt onto the boosters differently. the booster is designed to provide the proper amount of assistance when you apply the brakes. if you've ever disconnected the vac line off the booster and tried to apply the brakes you'll know what i'm talking about. so if you have the matching booster it's pretty easy to swap it in. my new booster was MASSIVE so it took a bit of finessing to get in there.

the 96-00 dx stock prop valve is 40/40


and yes do it! if you have upgraded your brakes you should, my setup feels amazing after upgrading to the correct sized mc and booster. pushes so much more fluid and gives me much better control over the brakes.
