Drums are worse because of the larger surface area involved.

I had an old pick-up with rear drum brakes and when they froze up the roads were icy. It left no traction to break them loose. Since I am retired now I no longer have to get out when the roads are icy.

My Frontier has only been out in snowy weather once in the nearly 8 years I have had it. Our band was playing for a funeral and the snow came in while we were playing.

Don't need any tire to road traction; just goose the throttle.

It didn't work for me. I had to catch one of the shop people to bring a torch out to allow it to release. Needless to say I never used the brake again during wet freezing weather.

Yikes. There must be harder ice in OK than CT.

Was it a drum or disc brake? Was it the brake assembly it self or the components leading to it? I know that older cars employed bare cables which were exposed to the elements.

Thanks!

The rear brakes were drum brakes. I think it was a combination of both the linkage and the shoes to the drums.

The parking brakes will reduce the wear and tear of your transmission. When people parking behind and in front of you bump your car, all the force goes to the transmission if the parking brake is not engaged. On graded slopes, the weight of your car is on the transmission. In severe case, it will cause "transmission lock up" where the weight of the car is preventing the transmission to shift out of park. You will need to unlock with the "unlocking slot" on the transmission.

Are some of the "rules" now different with a CVT transmission?

Like?

To my understanding, no. CVT uses the same type of parking brake that a traditional transmission uses which is a slotted inner ring that slides into place in an external slotted ring. One of the rings is connected to the driftshaft that goes to the wheels and the other is stationary.

I can speak on the use of not using the parking brake. I've rode in a car that rarely had the parking brake used. After a while, the car would actually rock back and forth for like 5 seconds or so unless you pressed the brake.

I believe ALL parking brakes are of the "shoe type". (There may be a rare exception but I can't name one.) If you have rear disc brakes than you will also have a drum and shoe incorporated which IS the parking brake. Many modern cars have rear disc brakes (with the drum parking brake). Older cars had front wheel disc brakes with only drum brakes in the rear due to manufacturing and sales cost. In school drivers Ed I was taught not to apply parking brakes in freezing weather because the shoe's could freeze to the drums.

Side note. It is easier to replace disc "pads" than drum "shoes". Except in the rear when the "pads" AND parking brake "shoes" must be replaced. Strangely at one time it cost more to replace "pads" than "shoes". Of course the anti-lock system now requires inspection. I don't know the cost now as I always do my own.
