Risk of poisoning and injury when handling brake fluid!
Swallowing brake fluid can cause symptoms of poisoning such as headaches, dizziness, stomach pains, vomiting, diarrhoea, cramps and unconsciousness.
A dose of more than 100 cm3 can have fatal consequences.
Contact with brake fluid can cause serious skin damage to unprotected skin.
Wear safety glasses and protective clothing such as rubber gloves.

| | • | Store brake fluid in original containers only.
| | • | Only store brake fluid in suitable, appropriately marked containers.
| | • | Never put brake fluid in beverage containers.

WARNING!
| |
Risk of accident due to lack of braking effect!
When the brakes are used for the first time after any work was performed on the braking system’s hydraulics area, the risk of an accident is increased due to an impaired braking effect.
Press the brake pedal several times to build up pressure in the brake system after finishing work on the braking system’s hydraulics area and before starting the vehicle.
| • | Hold the brake pedal in a pressed down position for approximately 30 s once pressure has been built up in the brake system, the pressure in the brake system must not drop during this time.
|
| |
WARNING!
| |
Risk of injury from moving parts!
When working on components which can be moved either by hand, by means of electric motors, or hydraulically/pneumatically via linkage, serious injuries can occur to body parts being trapped, crushed or severed.
Monitor hazard area.
| • | Secure area against unauthorised access when parts are in motion.
| | • | Never touch the mechanism of a component while it is being actuated.
| | • | Choose a test cable of sufficient length.

| | | 2. | Apply the footbrake several times to Make sure the brake pads are correctly seated.
| | | 3. | | | | 4. | | | | | | Care Point: | Carry out Carbon Ceramic Matrix (CCM) Brake Disc Condition reset only if brake discs have been replaced.
|
| | | 5. | Connect McLaren Diagnostic System (MDS), proceed to Diagnostic Toolbox within Electronic Stability Program (ESP).
| | | 6. | Access Sequences section.
| | | 7. | Carry out Carbon Ceramic Matrix (CCM) Brake Disc Condition sequence and reset the axle set where the discs were replaced.
| | | | | Care Point: | EPB calipers must be set in the fully closed position when any mechanical work is complete.
|
| Care Point: | The Parking Brake will be applied Make sure it is safe to proceed with this sequence.
|
| | | 8. | Proceed to Diagnostic Toolbox within Electronic Parking Brake (EPB).
| | | 9. | Access Sequences section.
| | | 10. | Carry out EPB caliper Closed.
| | | 11. | Carry out EPB Assembly Check.
