October 11, 201014 yr comment_333115 I just replaced both master and slave this evening. I used the parts out of the box without swapping any older parts. I did measure every thing before installing and the parts acquired from MSA were spot on. Regarding bleeding, my son sat in the car while I worked the bleeder. I had him pump three times and hold. On the 4th cycle it moved the slave and by the 6th I was pumping pure Dot 4. An straight forward job if ever there was one.

October 11, 201014 yr comment_333138 So i bled the system about 4 times myself (pita)Motive makes a nice pressure bleeder for European cars, they might have an adaptor for the Z's fluid reservoir. It takes all the pain out of bleeding brakes.Mike Link to comment https://www.classiczcars.com/forums/topic/37340-replaced-masterslave-cylinders-still-no-pressure/?&page=2#findComment-333138 Share on other sites More sharing options...
October 11, 201014 yr comment_333145 As MK1888 said, some makes and models require pressure bleeding. Some thirty five years ago I was working on a Slob, oops, I mean Saab and the hydraulics of the clutch didn't respond to gravity bleeding or the traditional pump and bleed. A Renault factory pressure bleeding tool which consisted of a bicycle pump, hose, and reservior lid was compatible with the Saab and solved the problem. Gravity bleed first then pump.

October 11, 201014 yr comment_333150 I've never owned any Datsun (and I've owned several!) that 'required' pressure bleeding. Normal bleeding will work if done properly and all components involved are is proper working order.

April 24, 201113 yr comment_353809 yeah i have a similar problem i replaced my slave and master cylinder. and i only have pressure if i pump the clutch pedal a few times. im thinking its air in the system because i didnt bleed the master cylinder by its self. but i also have a couple of questions im hoping you guys can answer.1. i hve heard you should use the old push rods on the new cylinders?2. do you have to bleed the master by itself?3. what else could be causing my problem? thanks guys Link to comment https://www.classiczcars.com/forums/topic/37340-replaced-masterslave-cylinders-still-no-pressure/?&page=2#findComment-353809 Share on other sites More sharing options...
