Time to work on the rear drums... Not exactly a fun day messing around with these things. A bad seal on the left rear wheel cylinder spells no more pressure ... Show morein the system (first picture).
So, as the Haynes manual says, take the wheel off and remove the drum (easier said than done) by beating the hell out of it. Then take a 30mm 6 point socket with a breaker bar and remove the hub nut.
The hub/bearing housing should slide right off, but it does not. The torque required to tighten this is between 135 and 188 ft pounds, this deforms a little part of the spindle where it stops the hub from sliding off.
A lttte bit of filing and it comes right off. Replace all the parts (easier said than done) and it looks good again... Show Less
