derk Posted January 5, 2003 Share #1 Posted January 5, 2003 Okay, found some time today and managed to get the master cylinder out of my 71. (Frozen in time, parked for a decade). This is the first of several posts of my weekend discoveries. One, I bought a new master cyl (in photo) but the reservoirs seem to be reversed, which makes me think it is for a 260 instead. Will this work as is? Can I swap the reservoirs? Does it matter? Yes, I could not get one of the lines off despite the new 10mm line wrench. I think I had already rounded it off too much with a Snap-On 10mm. Still looking for retailer of that hose new if anyone has any clues. Nissan dealer? Also when I got it off I found the white junk in there. Also photoed below. Cleaned it out but anything to be worried about? Thanks for your brains...

2ManyZs Posted January 5, 2003 Share #3 Posted January 5, 2003 You have a new master cylinder that is for the later 240-280's. The early 240's, up to 71 do have a master cylinder that is "bass-ackwards" in that they supply the front brakes from the front, that's why the larger reservoir is on the front and not the rear.You can use the new one you have, but you will have to reverse the lines on the bottom which will require a good bit of VERY careful bending of the lines. It can be done, it's either that or buy the more expensive correct master cylinder (I just paid 135 for one) so it's up to you. You might be able to get some brake line at an auto parts store with the ends, but you would need a double flaring tool and a bender to make up a new line yourself. You chould be able to get a new line from Courtesy Nissan, or a large dealer in your area, if no luck there, try MSA or VB. I know VB has the hard lines in their catalog, so you might want to try there first to save a bit of money.As far as the corrosion and crud in the brake booster, I've never seen one that didn't have it. It's probably caused by the water vapors etc coming through the vacuum lines off the intake. Clean it out and look to see if the inside is rusty, if not put a little grease in there and re-mount your master. Link to comment Share on other sites More sharing options...
