Poor braking performance in reverse gear
#2
If you have drum brakes there is a self adjusting mechanism at the bottom of the brakes that sets the shoes at the proper "tension" against the drum when applied in reverse. If these are missing or corroded your brakes won't self adjust. They also won't self energize if the mechanism is missing.

You may have a problem where the shoes have worn grooves in the backing plates in their normal position, causing them to hang up slightly when braking in reverse.
I'd be more concerned about the brakes not working well until the engine is warmed up. Is this due to lack of power assist or something else? This would only make sense if you are running metallic linings. The metallic linings are designed to provide maximum braking when hot. Metallics provide noticeably poorer stopping performance when cold.

Have you checked your brakes lately. A number of things can effect them.
1. bad rear axle seals causing brake shoes to be soaked in 90 weight oil
over a long period of time
2. leaking brake cylinder causing brake shoes to be soaked in brake fluid
over a long period of time
3. What Olds64 said
4. Brake shoes and the end of there life span
5. Vaccum leak on the power brake booster or the hose from the carb to
the booster has a leak
6. Master cylinder going bad letting the fluid bypass the plunger seal.
Needs a rebuild kit
Process of elimination by checking all sources that could cause the problem. Good luck and let us know what you find out

Perhaps "warmed up" was the wrong statement. In the morning when i start the car and drive, initially when the engine is cold the brakes don't work great, however this could be due to me not driving it at any great speed to begin with. When i eventually reach the high road and put my foot down, the performance seems to be OK.
