Rear E Brake Help??

[Kneale Brownson]

--
The emergency brake lever is held into the caliper housing by a small
peanut-shaped rod that fits between a concavity in the lever shaft and a
concavity in the bottom of the threaded rod on which the brake piston
rides.  To remove the E-brake lever, you need to remove the threaded rod
from inside the cylinder, which requires extracting an internal C-clip and
pulling out the rod.  That releases the peanut, which then allows for
sliding out the E-brake lever.  The chamber into which the E-brake lever
fits and the peanut-shaped rod are packed in a paste that looks like a very
thick petroleum jelly.  I can never remember whether it's 17, a lithium
grease, or 18, a lubricating paste, from this
