Cant remove front rotor is there a special tool?

You likely need a rotor removal tool, sometimes called a rotor puller. A standard C-clamp won't always work, especially if the rotor is stuck. These tools fit over the wheel studs and use leverage to pull the rotor off the hub. They're relatively inexpensive and readily available at most auto parts stores.

However, before resorting to a tool, check these things:

* Caliper is fully retracted: Make sure the caliper piston is fully compressed. If it's not, the caliper will be pressing against the rotor, preventing removal. You may need a C-clamp or specialized piston compression tool for this step. Never try to force the rotor off while the caliper is engaged.

* Rust or corrosion: Rust can weld the rotor to the hub. Penetrating oil (like PB Blaster) applied generously and allowed to soak for a while (even overnight) can help loosen things up. A hammer and punch *might* work to carefully break the corrosion, but be very cautious not to damage the rotor or hub.

* Correct orientation: Some rotors only fit one way. Double-check that you're trying to remove it from the correct side.

* Wheel studs: Ensure all the wheel studs are still firmly in place. A missing or damaged stud can make removal difficult.

If you've tried penetrating oil and a good amount of force (with the caliper retracted) and still can't remove the rotor, then a rotor puller is the next step. Improper tools or excessive force can damage your hub. If you're uncomfortable working on brakes, it's always best to consult a professional mechanic.
