Outer Limits 4x4 Board

im putting some 80 series diffs in to the 75 series to gain some extra wheel track, will i have too run the 80 series brake booster or the 75 series booster will be ok, the 75 series is disc brake front and drum rear as the 80 series is disc front and rear

thanks rob

did the same to my bj42
the bj had factory disc front end n drum rear

fitted the 80 diffs and have run the bj master cyl n brakes still work well , best to try the 75's first before outlayin the money first

Not a cruiser guru bit i'd run the 80 master ans prob also booster as it's set right to what the calliper size is and also with disc and drum differances there is a risidual pressure valve some one on here will know what way to go but i'd match it all up.
