is there a gasket or need for a gasket where the master cylinder bolts to the power booster? im fixing to replace my master cylinder due loss of brake pressure and this is my last place to check, i was told my booster could be filled with the missing fluid. is it true? i know ill need more fluid but i haven't found the leak in the system. the caliper seals, hoses, and wheel cylinders are all good and no holes in the metal lines. 94 DX coupe

you shouldn't need one if the one on it isnt crumbled away and if you do just make one

and yes you can get a bunch of brake fluid in there and it will ruin the brake booster eventually

is there a way to test the booster before i remove the master cylinder? someone used rtv to make a gasket ( before me )but i see no leaks near it or in any component else were. so im thinking its leaked into the booster.
