So my friends dad got him a 1972 Datsun 510. The owner said it runs but the rear brakes are locked up and the clutch lost its pressure. WTF does that mean? I never heard of anything like this. But now we wanna get it running but we dont know how...HELP!! Any one know about clutches losing pressure? If so how did you fix it?!?!? I need help 'cause we just dont wanna go blow off $$$ on parts that we didnt need to change...

I'm sure he's talking about the hydraulic pressure. Just bleed the slave cylinder and see if it works. If that doesn't work, make sure the master cylinder and slave are in good shape. If still you can't get it working, just pull the tranny and replace the clutch. This is pretty much 5 speed 101 stuff....

^What he said
Check the master cylinder and slave cylinder first for fluid, then leaks
