My first Datsun 620


Recommended Posts

Hi guys so just picked up my first Datsun 620 pick up truck

It runs and drive with a few old leaks but it's not stopping

The other guy that owned the trick installed a new master cyclinder

But the truck won't stop any place I should start looking at??

Or steps on how to bleed the system??

 

Thanks jc

 

I'll try post post some pics but am new on this site so give me time

Find a service manual. You have a load sending valve in the rear as part of the brake system. That and the brakes need to be bled in a certain way.

 

I am not a 620 owner. I have no clue how it works.

If I did though, I'd take the valve out and plumb the brakes normally.

Well, regardless of what the grumpy fucker above me says...I'm seeing 74s that have them. 

 

 

Get a friend, a bottle with a clear hose, some brake fluid and a wrench. 

Just get to bleeding and see if you have air in any of the brake wheel cylinders. 

 

 

It is also possible that previous owner did not bench bleed master, ruining it. 

 

 

 

Just attack and see what your results are.
