Remember my horror and disgust on finding the puny size of my brake master cylinder? Well the good news is I've found the correct part number courtey Nissan 4U.com. Now I just have to bite the bullet, source, order then hope it fits and works. Cap Saw says its a 99% bolt-on!
Part number for Nabco 15/16" Non-ABS brake master cylinder is 460105M422. Check your master cylinder properly to ensure it is a Nabco. Nissan uses two BMC suppliers - Nabco and Tokico. The parts between both makes are NOT interchangeable.
