Do automatics suffer more from "brake disc warping"

[anonymous-user]

I've been driving round in an auto hire car for a while and had a thought.

It seams that when people in autos sit at junctions and traffic lights, they tend to keep their foot on the brake and leave the car in drive.

I braked moderately the other day for some traffic lights from about 45 mph and then sat at the lights for a minute and thought that if i was in my manual car I would have taken it out of gear and put the hand brake on. In the auto I just sat with my foot on the brake.

I've read that its not the discs that are usually warped but part of the pad effectively sticking to the disc when it is hot and you leave your foot on the brake after hardish braking.

What do others do and do you reckon autos tend to suffer from "disc warping" more frequently?

Yes but not warping, brake pad material left on the disc.

Discs are dirt cheap so it's never an issue really.

I use the handbrake. Some people say that it's not enough to hold it, but that just means your handbrake is not good enough. Autos should be left in drive in order to pump oil through the transmission cooler.

Most new drivers are discouraged from using handbrake at lights etc
They are taught to hold the car with foot brake
Not like in my day!

Depends on the car but generally agree, on both our cars the disks are only ~£40ea and they're the top of the range. Cooking models are only about £30ea.
