You would probably get a few laps before the brakes started going away, it really depends on how ahrd you are on them, some could go around all day and not have to worry but others could stuff them in a couple of laps, how long was that piece of string

Just a tip, try driving around without braking at all for about five laps. Start off slow and work your way up to speed without braking. It is a good lesson in control when thing go wrong! You will learn how to throw the car at a corner to scrub off speed and catch it with the throttle when you want to straighten up and go again. Another thing to learn is stopping the car with the gears and handbrake (and I don't mean spinning the car to stop) Just in case the brakes ever go completely.

Using your gears to slow down is a good habit IMO not so much for just around town driving etc (but it does help) but it will save your brakes on a long decent and spirited driving especially for drum brakes  The number of people you see riding thier brakes on a descent of ~600-700m down several kms long is scary  people treat thier brakes a fail proof and immortal.
On a lighter note a friend told me in his surfy(fair while ago) days he had to select reverse to stop his combie

My brother was going up Mt Victoria pass (in the Blue Mountains NSW) in a Kombi and he had to go back from third gear to second gear and got reverse! They stop quick when you do that!

Reminds me when I was learning to drive in our (Dads) old yellow ute. I was changing up from 3rd to 4th and got reverse 
What amazed me was it didn't crunch and the first I knew about it was when the back wheels started skidding I quickly shoved the clutch back in and we keep going There has never been a problem with that gearbox and it is still going no problems.
OK it was on a gravel road and it was a ute so the back wheels were pretty light which probably went some way to saving the gear box. That ute is/was a great ute but was flat chat at 120 km/h

brakes are used for slowing, not your gearbox!!!! |

I can see that you have never raced a car with drum brakes!
So if you are going down a mountain pass you are saying that you should go down in 4th gear? I would throw it back to third (or second) and save the brakes till they are needed. |

I won't do it any good that for sure, but that's racing. You can bet on lowering the life expectancy of the clutch and synchros by going down through the gears, however that's the price to pay if you are going to take a car on the track and push it to its limits. Don't expect to take a car on the track and not have the bills that will go with it - its the law of motor racing and there is no escaping it. 
You will need to learn these these skills sooner or later - I had no brakes in an Mx-5 at Oran Park at the end of the straight after only 3 laps, and it was the gears / scrubbing of the tyres that managed to brings things to a stop.
