I've tried many MCs over the past 20 years. In the early days, I was easily enticed by the cheap aftermarket MCs. I thought if it was sold by the "nation's foremost Land Cruiser restorer" (in Texas), it must be good stuff. Today, I can tell you there is no way I will use a MC that is not made by Aisin / Advics. The junk MCs I got typically lasted half as long, and then it dripped brake fluid into the brake booster, taking that out as well. I won't forget that moment after I installed the OEM MC for the for first time, after many years of owning my Cruiser. It was like, damn I can't believe all these years I thought lousy brakes was normal!
