Yikes! You were riding with the Angels for sure and some alert drivers as well since they didn't hit you as you were sliding along.

Best news is that you are here to talk about it.

Steve.

My word Roger I'm glad you're here to be able to talk about your close shave. I think tonight there will be a lot of forum members busy with checking over their coaster hubs for faults.

Wow! Crazy story.

I took one final test ride today before I start riding to work again tomorrow.
After the bike warmed up it started running better than ever! I think it liked the colder temps. It was about 50 deg.
It will be around 40 in the morning for my first couture sixpence i parked it last year (2012) when I started trouble shooting electrical issues.

Wondering how traffic will react to my whelan flashing police taillight.

I started hearing my pedal-side chain guard getting rattly so I took it off and re-did the rivets. Now it's sorted.
Of course while doing that I found another issue. My new rear fender was cracked half way through. As it's pre- paint job still, I chose to do some creative custom work with some ally sheet and a rivet gun.
A warning before looking at the pic: some viewers may experience feelings of jealousy at the craftsmanship used.

Rogergendron, sorry to hear that problem, but lucky your OK!

I was thinking about coaster brakes doing that recently. I friend of mine got a bike and it would lock up occasionally. He used it hard though. I looked and saw that at one time the clamp that holds the arm for the hub came loose. That I told him was causing the problem. But after that was fixed by getting the clamp bolt back in place it still had problems. Some times he would pedal and it would just slip.

For myself I just know if you don't have hand brakes, at least one as well as the coaster brake, what happens if the chain falls off and you going down a big hill. It happened to me.

http://motorbicycling.com/showthread...842#post532842 page 1 post 5 I replied to this thread about that experience.

Getting rid of coaster brake all together, I can say I did just a bit more (no pedal crank), but it is not legal on roads, only off road in motor cycle parks or private land. It was a bicycle but now it is classified special motor cycle by DMV.

Wow Roger! I am glad that you are still with us!
You must have had some Angels watching over you during that crazy ordeal.

Sheldon has a tutorial on how to make a simple jig to hold the brake perches perfectly for welding.

http://sheldonbrown.com/cantilever-fixture.html

I totally agree with your decision to convert over to direct pull brakes.
They do stop better and are much easier to service.

yep and this is what you should be looking for !!!!!!!!!

1 there was excesive wear on the break shoes themselves but hard to see from the low quality photo
2 the pad snapped from the shock of a simple and normal pressure back pedal, i guess a normal back pedal at 35mph is probably placing 5-10 times the force on the pads it normaly would at 10mph lol
3 when the pad broke the smaller piece slipped out of the spring and cup and flipped up sideways and gouged into the inner wall of the hub causing extreem gouging and scoring and nearly instantly siezed the wheel ! you want to cheack for scoring of the hubs inner wall when regreasing and going over your coaster hub ! excessive scoring in only one spot could mean the pads are not contacting correctly with there full surface aria.
4 the broken pad smashed the spring that squeezes them them together and snapped it. you want to make shure that spring is not worn and has pleanty of elastisity.

this was just a generic coaster hub IE shimano 110 style..... its a hub a lot of people use so pay attention to it and i recomend a over haul every 1,000 miles !!!! lol if i had done one at 1,000 miles i would have seen that the pads were worn and were grinding a score into the hub wall and i could have replace the pads and sanded the hub wall smooth with scotch bright and saved myself a lot of trouble and a rear hub !

most hub aare similar unless you have seaed multiple gears but most are just like this, some may have 3 or 4 pads some have 2 but the designe is similar and if a pad breaks at 30 - 40mph.......... you better have been drinking red bull cause your going to need wings !!!!!

luckily i only have a small bruise on my knee where it smashed the gastank when the pedals locked up and spun with and at the speed of the tire ! its when i tried to pull the clutch in and break by back pedaling when all the fun happened lol !


edit....... i honestly can not believe i did not fall..... it was the longest skid i ever did in my life, in the snow tooo ! well aside from in a car on pourpose but lol thats another story. it was like in my head i was thinking ahhhhhhhhhh shiiiiiiiiiiiiiiiiiiiit ahhhhhhhh goooooona faaaaaaaaaall gooooona faaaaaaaaaaal aaaahhhhhh here it comes..... gona faaaaaall .......... never happened lol i stayed up the whole time with some creative front breaking ! wow........wow.... it was like i just kept going in a slow mow long ars skid.... LOL

tektro makes a very nice caliper brake that will bolt right to the rear fender mount - there are clones of this brake cheaper too

the compound calipers have almost the stopping power of disks

any way ...... enough of that.....lol


i got rid of the coaster break all together and now have the 7 speed shimano cassett and shimano derailure setup hooked up, but i have no cable long enough to make it to my handle bars, plus i am going to have to use a right side 7 speed twist shifter that i have .... upside down on the left side so it will not interfear with the throttle. no worries it will look and work just fine... only the numbers will be upside down lol ! that and i need a master link for the 21 spd mnt bk chain i pulled from the doner bike, right now i am running a bmx chain on the center gear with the derailure set to that position. it works just fine for now but i cant wait to hit up the bike shop later for
1 a new long cable
2 a master link for the multie speed chain
3 a large side pull rim break for the rear (just untill i get the post for the v breaks welded on)
4 a dual pull break lever

ohh yes .... i just installed a 36t chainring and greased up my bottom bracket, the bike should be real easy to pedal with a single 36 and 7 speeds, it just seemed like the right gear ratio for a heavy cruiser... i think with a 40 or 44 it would be to hard to pedal to be able to use all the gears making them useless lol i want to be able to use em if i have em so i went real small on the chain ring sprocket, at least now i will be able to pedal through all 7 gears if i want.

after all that lil stuff i should be able to tune in the shifter and adjust bolth breaks on the one lever and my bike will be the sweetest cruiser in town !

sorry about the lighting my bike/ engine shop is a large room in a basment with only a single light lol i use a small lamp where ever i am working and the cieling light just keeps it bright enough so i can see enough to find my tools and move around, its cool though i have a masive 20ft x 20ft room all to myself just for tools, bike stuff, equipment and engine building !
