alright guys, im replacing all my brake flex lines to extended ones and gonna have to bleed all the brakes anyway, sooo , is it really worth it as far as an upgrade to replace my origional master cylinder to a 1"? and is it really as simple as getting the v6 pre-96 4runner and bolting it on?

 

Is there a 1" mast cyl that will fit the firstgen booster?
I know the dual diaphragm booster will not fit in a first gen, and the 1" MC i acquired has the dual bolt pattern versus four (Firstgen) bolt style. I did manage to find a 15/16" from an 89? 4runner or p/u. idr atm.

 

Its only worth it if you step up in size on the caliper.
They go hand in hand. v6 master....v6 calipers. Dont do one without the other.

 

Like hilux said, a 1'' booster is an ingredient to a recipe. If you replace only the master the pedal will be very hard. People say replacing the booster only is a very good upgrade though, I just don't know which one fits bolt on, appart from the turbo one, which is so rare I'm not sure it even exists! :p
