Nate...
I considered "stealing" the master off my '85 SD "parts car" but-- I guess I'm not ready to say "goodbye" to Mildred.. *even though I could use the space* Had the reservoir broke-- it would've been a donor..
I bought my first set of speedbleeders for my BMW (motorcycle) probably 10 years ago. When I replaced them on my '97 Passat TDI, the SPEEDBLEEDERS were $7, the plain replacement bleeders were $15 each almost everywhere (more than that from the stealership). They were pretty rounded by previous owner(s).. Some people don't realize how LITTLE torque you need to close a bleeder valve. ;)
Anyway--
They're simple enough my daughter will be able to do her own-- and yes, I'm teaching the 16 year old lady to care for this beast. I'm hoping I can make it a resto-daily driver, she can keep "forever..." :)
