Question:

Motorcycle rear brakes - Drum or Disc?

Which do you feel is a more better braking system to have on your motorcycle's rear tyre/wheel, and why do you think so?I know that the disc brakes have more longevity compared to drum brakes and require much less maintenances as well. However, I've always been afraid that the tyre might lock if the rear brake is applied to hard which may cause us to lose control. Is this true.?!

Answer:

Love the disks, the control, the quickness, the ability to lock if you push it there, how they are reliably there and always the same without variance in different conditions. But I may be far influenced by super sport bike as the strongest sensation of road feedback I have ever experienced.
Any functioning brake system ( whether it be disc or drum ) will lock, assuming no ABS, if you apply enough pressure to it. I prefer a disk/pad set up as well. It dissipates heat faster and is easier to service ( you can replace the pads without having to remove the wheel ).
The same force will lock the wheel and USUALLY causes a crash. IF you worry about wheel lock up, spend the cash for ABS, they use Discs. Am EXPERIENCED rider and pump the rear brake 4 or 5 x/second but no knowledge where the lock point is, ABS does it 100x/second to the very edge of lock up, MAXIMUM stopping.
I only use rear brake to square up a corner when I ride dirt. 85% plus stopping power is your front brake anyway. Disc all day long. Ridden plenty of things with drum, I will always take disc. ABS will never replace riding skill. I can lock up abs just as fast as I can any other brake system.
I've had both and if set up for the bike they are on and maintained correctly, I have found absolutely NO difference between a drum and a disc on the rear. Yes, locking the rear wheel can cause a loss of control, but it's not an automatic loss of control. Take your bicycle out into some gravel and lock up the rear wheel. It fishes around a bit, but it's mostly controllable until as long as you keep the rear wheel lined up with the front. On a motorcycle, it's the same thing, only with a heavier motorcycle and the potential for faster speeds. The only way to get used to the bike with a locked up rear wheel is to practice. Start slow and keep your speeds down. Ease on the rear brake until it locks and then ease up until the wheel starts spinning again. The biggest thing with a locked rear wheel is to not let the rear wheel slide too far out of line with the front wheel and if it does start to swing, don't let off the brake suddenly - that will cause the rear end to snap suddenly back to center and may throw you off the bike. If you find yourself in a rear wheel skid, ride it out. If you can, you can try to ease off the rear brake and let the bike slowly straighten out. Otherwise ride it to a stop.
