Bleeding older C30 drums?
« on: November 04, 2021, 05:58:23 PM »
The gap between the backing plate and the leaf springs is less than an inch.  I got a long handled 3/8 with a bent head to get into opening the bleeder valve.  But heck I'll never get the bleeder hose on.  Is there a special bleeder hose or something?

Surely somebody has bled the drums on an early 70's C30?  I guess I could always remove the leaf spring entirely...

That configuration is a head shaker for certain.  There is no trick, really.  It is a matter of finding a long straight bleeder wrench with a suitable head angle and then gravity or pressure bleeding.  Bleeder wrenches are superior to open ends because they are less likely to damage the bleeder screw.  The fluid can be washed off the spring with plain water when done.

You don't need a hose. It sure helps save the mess but is not necessary. Most vacuum bleeders come with 90° fittings

This is enough of a pain that I started researching disc conversions.  But turns out dually's with stock wheels don't convert.  One last thought is to tear down the brakes again to the wheel cylinder and use a reverse bleeder that pushes fluid into the wheel cylinder.  But not sure if this would damage the wheel cylinder pistons since it would all be unassembled.
