Repair Instructions

Addressing Low Brake Fluid:
- If the brake fluid is low, add the appropriate type of brake fluid up to the "MAX" line on the reservoir.
- If the fluid level drops again shortly after, check for leaks in the system.
Replacing Worn Brake Pads:
- Lift the car using a jack and secure it with jack stands.
- Remove the wheel to access the brake assembly.
- Use a wrench to remove the caliper bolts and slide the caliper off the rotor.
- Remove the old brake pads and replace them with new ones, ensuring they are correctly positioned.
- Reattach the caliper and wheel, then lower the car.
Inspecting and Replacing Brake Rotors:
- If the rotors are damaged, they may need to be resurfaced or replaced.
- Use a torque wrench to ensure proper torque specifications when reassembling.
Fixing Brake Line Leaks:
- If a brake line or component is leaking, replace the affected part. Use a wrench to loosen the connections carefully and replace the damaged line or caliper.
Testing the System:
- After repairs, pump the brake pedal several times to ensure proper pressure is built up.
- Start the car and check if the brake warning light is still illuminated.
- Perform a test drive at low speed to ensure brakes are functioning correctly.
Final Checks:
- If the warning light remains on after these steps, further diagnostics may be needed, possibly involving checking the ABS system or seeking professional help.
