Brake and Clutch pedal locks work as a mechanical immobiliser by disabling the pedals so that either the brake or clutch (or both) is fully applied in the car unless the lock is released, making the car undrivable.

There are a few different systems, with cheaper ones working as a brace between the steering wheel and the pedal, and more expensive versions bolted to the footwell floor, locking and clamping the pedal in place. The second set is the version to go for if you can afford it, as the brace versions can easily be removed by the thief  forcing or cutting the steering wheel.

These locks are a great visible deterrent to criminals and while not as widely available as steering wheel locks, can still be bought at most good car accessory stores.
