Disk Brakes?

[WouldBeBiker]

Just bought a rear mag wheel from CDHpower to replace my walmart wheel that has a busted spoke and is starting to be not so true. What all would I need to get a disk brake set up going for that? Currently just using the rim brake that came with the bike but it's broken for a while. Would really like to have two brakes now that there's an engine on it.

What size of sprocket do you have for your wheel?

Here is a full kit minus the mount for the caliper. I suggest you make one like @DAMIEN1307. It will be much more purpose built if you make it your self

That depends on what size your rear sprocket is...That determines the size of the disk rotor you will need so the caliper and chain and sprocket do not come into contact with each other...That would also bring up the question of whether your frame was built as disk brake compatible or not, as well as what parts you would need to adapt disk brakes to your bike and if there is something off the rack you can buy to do this or if you have the mechanical abilities to fabricate your own as I did.

Notice how very little space I had to work with on my bike...I am using a 36 tooth sproket with a 203mm disk rotor...I can just barely slide a matchbook cover in between the caliper and the chain, thats all the clearance I have with my setup.

The only problem you have with ordering that kit is both disk rotors are 160mm disks...That won't work in the rear due to sprocket clearance issues...I needed a 203mm disk rotor which I have ordered separately.

Yeah, I forgot you needed a larger disc rotor

This is why we keep ya around here

That's why I asked what size of sprocket he had on his bike.
