Solution: Refill the brake fluid reservoir and inspect for leaks in the brake lines or seals. If leaks are present, repair or replace the affected parts.
2. Air in brake lines
Air in the brake lines can cause a spongy feeling when pressing the brake pedal, leading to reduced braking power.
Solution: Bleed the brake system to remove the trapped air. Use a proper brake bleeding tool or have a professional perform the bleeding procedure.
3. Worn brake pads
Brake pads wear down over time, reducing braking efficiency and increasing stopping distance.
Solution: Replace the worn brake pads with new ones. Inspect the rotors and calipers for additional wear or damage during replacement.
4. Damaged brake rotors
Warped or damaged rotors can cause vibration or reduced braking performance.
Solution: Resurface or replace the brake rotors. Ensure the rotors are within the manufacturer’s thickness specifications.

A malfunctioning brake caliper can cause uneven brake application or sticking, affecting the vehicle’s handling.
Solution: Inspect the caliper for damage or seizing. Repair or replace the caliper if necessary. Clean and lubricate the caliper slides during maintenance.
6. Brake hose leaks
Leaks in the brake hose reduce hydraulic pressure, leading to ineffective braking.
Solution: Replace the leaking brake hose and refill the brake fluid. Bleed the brake system afterward to remove air.
7. Master cylinder failure
A failing master cylinder can lead to a soft or sinking brake pedal, reducing braking effectiveness.
Solution: Replace the master cylinder. After replacement, bleed the brake system to ensure proper pressure.
8. Brake booster failure
A failed brake booster can make the brake pedal feel hard, requiring more effort to stop the vehicle.
Solution: Replace the brake booster. Ensure the vacuum supply to the booster is functional before replacing.
9. ABS malfunction
An ABS malfunction can cause the ABS light to illuminate and affect the vehicle’s braking system.
Solution: Use an OBD scanner to check for ABS error codes. Repair or replace the faulty ABS components based on the diagnosis.
10. Stuck brake caliper
A stuck brake caliper can cause constant friction on the brake disc, leading to overheating and premature wear.
Solution: Lubricate the caliper pins and inspect for rust or debris. Replace the caliper if lubrication does not resolve the issue.
11. Contaminated brake fluid
Contaminated brake fluid can reduce the boiling point of the fluid, causing brake fade or failure.
Solution: Flush the brake system and replace the brake fluid with fresh fluid. Ensure the brake fluid reservoir is sealed to prevent future contamination.
12. Brake line corrosion
Corroded brake lines can lead to fluid leaks and reduced brake pressure.
Solution: Replace the corroded brake lines with new ones. Inspect the entire brake system for additional signs of corrosion or damage.
