My brake master cylinder on my s14 has become useless. I would like to purchase a 300zx master cylinder, as im going to do a 300zx brake upgrade. I'm not sure about which master cylinder brand to purchase. Here is one that im considering:

What do you guys know or think about this master cylinder?

Do you guys have suggestions on places to purchase a master cylinder, or a particular brand to buy?

All of your help is much appreciated
