i have a bad brake fluid leak coming from my car.it's coming from the round black cylinder looking thing that's just behind where you put the fluid into.is this the master cylinder ?? or is it just a resevoir for the fluid?? it seems to be coming out right at the front where the hose from the top up container attaches to it. can you fix the problem with a gasket?? any help would be great thanks.

 

it's your master cylinder that is leaking INTO the brake booster (Black thingie)
REPLACE IT ASAP, otherwise you will destroy your brake booster.

 

it's coming out of the front where the screws are.

 

Like internetautomart said...REPLACE IT! asap...Otherwise you will need a brake booster also..

 

If you are going to switch master cylinders, you can check with autozone to see if you can buy a remanufactured(repaired) master cylinder. When I got mine for my 2nd gen it was a remanufactured OEM nissan master cylinder that I received(said nissan on the side, no sticker, looked original). 6 months later, no problems. Pretty sure it is the same with 3rd gens

 

He lives in australia...

 

is it a hard job to replace the brake cylinder? are there instructions on this site? cheers
