Removal
1. Prepare the car for work ("Preparing the car for maintenance and repair").
2. Press the lock to disconnect the wiring harness connector from the switch.
3. Using a 19 mm open-end wrench, loosen the lock nut of the switch.
4. Remove the switch through the slot in the bracket.
5. Using a multimeter in ohmmeter mode, check the serviceability of the switch. When the switch button is in the free position, contacts 1 and 4 of the switch should be closed, and 2 and 3 should be open. When you press the button, contacts 1 and 4 should open, and terminals 2 and 3 should close. The faulty switch must be replaced.
Installation
1. Install the brake light switch in the reverse order.
2. After installing the switch, make sure that when you lightly press the brake pedal, the brake lights turn on, and after releasing the pedal, they go out. If necessary, adjust the position of the switch (see below).
Adjustment
Note: When the brake pedal is not pressed, its lever should rest against the switch. If the switch presses the pedal, then there may be no free brake pedal. which will ultimately lead to incomplete release of the brake mechanisms. If there is a gap between the pedal lever and the body (threaded part) switch. then the switch rod will not be fully recessed and the brake lights will be on.

3. To adjust, use two 19 mm keys to turn the nuts and move the switch...
...ensuring that the switch rod is pushed all the way in and that the switch does not move the brake pedal forward.
