Not a bad idea to use a lower gear to maintain desired speed downhill in mountains.

Brakes are NOT for prolonged use.

Also no need for true double clutching with modern transmissions. What you're likely doing is sometimes called half double clutching and is simply rev matching prior to engaging clutch, which should always be done. True double clutching is moving gearshift to neutral and then engaging clutch and speeding up motor to get trans gears up to speed prior to then declutching and moving the gear lever to the lower gear. Synchromesh accomplishes this for you.

PS: I checked page 31 of my copy of the April, 1970, issue of Road & Track (first 914 test) ... the 914 is a 4- wheel disc brake car.
