[Healeys] Rear Brake Problem

[John Sims]

Only thing that I would add to this is to change the phrase "(take picture
if necessary)" to read "it is mandatory to take more pictures than you think
that you will need" One of the best  tools for any garage is a digital
camera.

re: " any suggestions about installing these on the reat brakes."

- observe current installation (take picture if necessary)
- clean all internal parts thoroughly with brake cleaner
- back out the adjusting screw--collapse the adjuster wedges--all the way
- get new felts for the standoff pillars if necessary
- put a drop of heavy oil or light grease on the end of the felts
- install the springs--there's some evidence the original springs are
different lengths, but replacements are the same. If yours are different
lengths refer to the shop manual for correct placement
- make sure the shoe ends are 'opposite'--i.e. there's a square hole on one
end for the 'hook' on the slave cylinder and a solid end on the other--make
sure the solid end butts against the backside of the cylinder (someone on
the BCF had 'hole-to-hole' and it caused binding )
- install the new shoes with springs and make sure the lining surface is
orthogonal to the backplate (not sure what the scientific method is to
accomplish this--I use a carpenter's square and mark one eyeball)
- make sure the shoes are centered; i.e. the lining edges are equidistant
from the edge of the backplate all around
- clean all internal parts thoroughly with brake cleaner and wipe down the
shoes with clean cloth
- clean inside of drum and install
- adjust with parking brake off (maybe even detach the cable--I don't and
haven't had any issues)

I reported earlier about a driver side rear brake problem on my 67 3000.
When
backing up, the brake would tighten up. Went away when driving forward. Had
not used the foot or emergency brake prior to this. Removed the drum and
found that part of the brake shoe lining had fallen off the shoe and was
lodging in between the remaining shoe liner and drum. Cleaned out the liner
pieces and works fine now.

Ordered a set on new brake shoes and was
wondering if there are any suggestions about installing these on the reat
brakes.

Thanks,

Jon
