Parking break

[Lordphilgood]

My 1970-C3-350 parking brake needs looking at (Doesn't hold, rubs while driving & sounds like something has fallen off when reversing) but I don't have any manuals/digrams on these, all I have been told is they are drum breaks, inboard on the axle.
I've only had the car for 2 months and was told that these were worked on prior to my ownership & looks like new cables were fitted, but before I jump in blind to investigate can anyone offer some guidance, advice or at least an exploded view of what to expect.

C3 parking brakes are generally accepted as being pretty useless. So useless that even if in good working order they will struggle to comply with MOT tests. Any MOT tester who has had experience with C2/3 Vettes will know this and understand the systems limitations and pass the car - knowing its as good as it will ever get.
The brake shoes are probably a similar size to a Honda moped - if you over exert the handbrake lever there is the risk of the shoes flexing/distorting and the bonded linings may crack and ultimately break-up. Handbrake cables tend to stretch. So after stripping the brake hubs down and establishing whether or not the inner drum surface is useable perhaps order-up a new set of shoes/linings, all new parking brake parts and a new cable from Gavin. Its a fiddly job replacing the brake shoe springs - but do-able. If set-up and adjusted correctly the set-up can work quite well if you keep on top of the adjustment.........or just ignore it (which is what most owners do)
