I think the master cylinder is leaking, there is fluid leaking down the front of booster. How can I tell if its the master or the booster??

 

it's probably the master cylinder. but make sure fluid is not just leaking from around the resevoir. i don't think it's the booster because it only contains air and no fluid is actually in it. anybody correct me if i'm wrong.

 

Master - when installing the new master, its easier if you connect the lines first, then tighten the nuts. If you do it in reverse, its a pain in the **** to get the lines started.

 

yep, master cylinder.

Don't forget to bench bleed the MC. On the bench out of the car or in the car if you forgot, but the latter can be messy if you have two left hands. The new MC should come with rubber lines and plugs and instructions on how to bench bleed.

Good luck,
