I need a famous-to-be-strong backward-pedaling (coaster ?) brake for my back wheels

I have driven about 200 miles the last 3 weeks testing my quadricycle in my city (Chihuahua, Mexico) which streets look like the streets of San Francisco, up and down that is, making my body lose a bunch of pounds...

I replaced the front and back brakes by a single-speed backward-pedaling system for a safe -but still cheap - brake system but I do not really trust it. I have to tighten the main screws every two days, it is loosing oil, and because I like safety, I just hate it..

We all have used this system when we were young, and I am surprised to only find a cheap and bad one for sale in Mexico.

Do you know of any proven and famous-for-being-undestructible backward-pedaling brake system which I could order from Internet ? My place is quitre dusty, so it should be also dust-proof.

Thank you

Philippe

If i was you i would loose the idea of a coaster brake setup (the back pedal brake) because their really isnt a good strong one out there, especially considering the weight of your bike. I would look into outfitting it with a disc brake setup if possible, you would need a disc brake wheel and a cable brake setup so it would be a little more expensive but alot safer.

a good brake that is still cheap is the avid bb-5 and you can get one online here http://www.pricepoint.com/detail/157...ke-'07.htm

a strong and cheap wheelset that would work with it can also be found here http://www.pricepoint.com/detail/132...-Lite-Rims.htm

good luck in your searches, pics of the quadricycle? It would be really cool to see what your pushing up those hills

Thank you.

I intend to use this quadricycle for foundations so I would like to make it as cheap as possible. I am not sure about a front disk brake, which would obviously be great, but isn't it just to complicated for third-world countries to repair and find spares ?

Really this is a big surprise for me that not coaster brake can be just strong enough. This is a very old technology, isn't it ?

I understand wanting to make it as cheap as possible completely, its just working in a shop i see every day people trying to cut corners and use equipment not designed to what they are doing and it always costs them twice as much plus a few headaches along the way. One saying that i have found to be true is "the poor man pays twice" Meaning alot of times when you take the cheaper route it ends up giving you problems and you end up buy the better part anyways.

Coaster brakes are a very old technology, it was never intended for extreme use though, they were more intended for beach cruisers and kids bikes.

Most disc brakes are very very reliable, especially the avid one i sent a link to. About the only attention they need are simple cable adjustments (just like any other cable brakes) and the occasional pad change. Even on my mountain bike that is ridden in pretty rough conditions gets over a year out of a set of brake pads.

If you would carry an extra set of brake pads with you if your leaving home for any extended time i think that would be all you need.

If you cant do the disc brake thing still i would at least look into a good rim brake set-up like a set of v-brakes that should be easier to find brake pads for.

Coaster brakes are shyte. Even the best ones aren't very good. They are good for bikes that never go really fast, and never used that often.

Coaster brakes are fine. For bikes. Quads do put a lot of extra weight on what is essentially a tiny drum brake. And losing oil? I've never seen a coaster brake hub with effective seals. It doesn't surprise me it loses oil. Coaster brake hubs are usually greased, not oiled. Preferably with a high temperature tolerant grease.

Poor man's brake? Maybe a scrub brake? You know, the kind that rubs against the tires?

Thank you for your interesting answers and the unanimity about the coaster brake being a bad idea for a quad.

I will then go for a disk brake. Nubcake, I cannot figure out whether the disk brake you directed me to includes the rmetal disk or do I have to buy it on the top of the brake system ?

My problem is that I will pay USPS more than the disk brake itself :-) I will try to find it in Mexico.

Thanks again.

The disc brake will come with the rotor and hardware needed for a typical install.

If i was you and would have to end up buying online and having it shipped i would recomend getting together a list of EVERY part you need from that company and order it all at once to save yourself the shipping charges.

Let us know how it works out
