I have a cannondale scalpel with sram level tlm brakes. After riding and I go to stop both the front and rear brakes work but they won't release. I've read this is a known problem and sram will fix it so I called the local sram bike shop and they won't fix it because I don't have the original receipt. So I guess I'm stuck trying to fix it. Does anyone know what I need to do to get these brakes working properly? Thanks

I seem to remember its the lever master pistons that stick when it's hot and return to normal when cold. I'm not sure if you should replace the piston, the lever body or both. In any case, a pair of new Deore brakes cost less than 100€, brake better and have way less issues. Depending on the parts cost to repair them, it's probably not worth it.
