Just bought a new totally stock Huffy Cranbrook. I like the bike pretty well. The coaster brake does slow it down and stop it, but the thing won't lock up the rear wheel. I'm now 64 and it's probably been 55 years since I rode a coaster brake's bike. What is normal for these? Should they be able to lock up the wheel? Is there a break in process on these? I picked a bike from Walmart that had no scratches to speak of, no dents, the wheels are pretty well true. I know I have 30 days to return it. I would no doubt forfeit the $20 registration fee, which is mandatory on all new bikes bought in the state of Hawaii. I shot off an email to Huffy to see if they might send me a new rear wheel. I'd kind of like to keep this bike, and was considering adding a front hand brake kit to supplement the somewhat weak coaster brake. Also, I did order a bicycle tool kit, as I am maintaining my 35 year old daughter's bike, and realized that I had, for instance, no super thin wrenches for setting the loose ball bearing to cone preload properly on her single speed Thruster Fixie bike.
Am I expecting too much from a rear coaster brake?
