It sounds like you need to start by getting at least the rear wheel trued. If it is wobbling so much that the brakes have to be spread that far, it REALLY needs some attention with a spoke wrench.

The curved metal thing is called a noodle. If power modulators are a little pulley device to pull more cable, you might not want them, as it will let the brake move farther, but you will have to pull harder.

Replacing thicker cone spacers with thinner ones will move the arms in closer. But get your wheel trued first.

You probably don't even need a new wheel. If you know a decent bike shop you can take the wheel to them and have them true it. It simply means adjusting spoke tension so the wheel is nice and round again.

The 'power modulators' you linked to would actually make your braking worse under the present conditions. What those do is use a spring in them to give you more brake lever 'feel'. This means that it would be more difficult to lock up the wheel, but would require more cable pull, not less. I personally wouldn't recommend them unless it feels like the brake levers don't move far enough before they hit the rim. If they move too far already, it would only make things worse.

God bless!

As the others have stated, first get the wheel trued/replaced.
If you WANT to lock up the wheels, replace the modulators with plain noodles. That will give you the max effect on the wheel for the force on the brake lever.

How much is a wheel "tureing"

AND DONT START WITH PANIC STOPS! thats the reson i started this thread... i always knew there was somthing mushy about my brakes, they slowed me down real good but they didnt lock the front wheel as others did... so i blamed the power mods and i was right aperantly... ok back to PANIC STOPS! i was going maybe 30-40kmph downhill and i knew theres a crosing at the end.. i saw it turn red and i was sure i could make it... thats right i was SURE... lol from 40 to 0 in 5 meters and a stopie all the way lol i was LIKE MOTHER and acted like nothing hapened... i do stopies as much as posible... so i wast scared just the ******** trafic! well ill get a pic of the skid mark lol and how close its to the street before the intersection...
i slamed the front to the max ( lever to bar) and i wasnt sloing down fast nuff so i hit the rear brake like less than a sec later... and i got the skid/stpoie cause i tried to put more weight on the front... and ended up a foot away from the street... well thats my story...

and yeah wheel truing or new wheel prices.... and NEW NOODLES how much?

thanks

If your rear wheel has that much wobble you almost surely have a bent rim and need to replace it.

You can screw around with some half way measures but, until you solve your bent rim issue, you are just going to go from one problem to another.

I can think of two different type of 'little metal ends':

A ferrule is a little metal cap with a hole in the center that is slid over the end of the cable housing.
An end cap is an even smaller cap that is crimped onto the end of the inner cable to keep it from fraying.

You should be able to get either one from a bike shop for either free or cheap.

God bless!
