Disk brakes

i have a trek commuting bike that has Hayes so1e disk brake system. The seals have all leaked out their fluid and I want to replace the system. So the question is what can I use to replace it with out changing the disk..

If the rotors are as old as the brakes, you might need to replace them too.
Rotors have a minimum thickness of around 1.5mm, manufacturers say to replace them when they get to that thickness.

Are your brakes post mount or IS mount?

Depending on your current setup, you might need to get some adapters to fit new brakes.

Bikes: Too many. Cannondale SuperSix, Trek Remedy 8, Trek Crossrip+ get the most ride time.

If the rotor is in good shape you should be able to use it with different calipers. In the past there were some rotor sizes that are now uncommon--pretty much everything is 140, 160, 180, or 203 mm. If it's a different size than those, you may need a new rotor or possibly slightly shim the brake caliper away from the frame (for 185mm rotors, for example).
