•Reduced braking performance or longer stopping distances
•Brake fluid leak observed underneath the vehicle

Diagnostic Steps

1
Inspect the brake fluid level and condition in the master cylinder reservoir.
2
Check for any visible leaks around brake lines, calipers, and wheel cylinders.
3
Scan the vehicle's onboard diagnostics for any trouble codes related to the braking system.
4
Perform a visual inspection of brake pads and rotors for wear or damage.
5
Test the brake booster functionality by applying pressure to the brake pedal with the engine off, then starting the engine to see if the pedal drops.
6
Measure brake pad thickness to ensure they are within manufacturer's specifications.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

Solution

1. Preparation

Gather all necessary tools and parts before starting.
Ensure the vehicle is parked on a flat surface and secured with wheel chocks.
Wear safety goggles and gloves for protection.

2. Inspect and Replace Brake Pads

Raise Vehicle:
- Use a jack to lift the vehicle and secure it with jack stands.
Remove Wheel:
- Use a socket set to remove lug nuts and take off the wheel to access the brake assembly.
Remove Brake Caliper:
- Unbolt the caliper from the bracket using a socket set; support it with a bungee cord or rope to avoid straining the brake line.
Inspect Brake Pads:
- Check the thickness of the brake pads; if they are less than 3mm, replace them.
Replace Brake Pads:
- Remove old pads and install new ones, ensuring they are seated properly in the caliper bracket.
Reassemble:
- Reattach the brake caliper and wheel, then lower the vehicle.

3. Replace Brake Fluid

Remove Old Fluid:
- Use a brake fluid vacuum bleeder to extract old fluid from the master cylinder reservoir.
Add New Brake Fluid:
- Fill the reservoir with the recommended brake fluid type (DOT 3 or DOT 4 as specified in the owner's manual).
Bleed the Brakes:
- Start at the wheel farthest from the master cylinder (usually the right rear), and have an assistant pump the brake pedal while you open and close the bleeder valve on the caliper until clear fluid flows without bubbles. Repeat for each wheel in the correct order.

4. Inspect and Replace Brake Rotors (if necessary)

Measure Rotor Thickness:
- Use a micrometer to measure the rotor thickness; if it's below the minimum specification, replace the rotor.
Remove Rotor:
- Unbolt and remove the caliper bracket and rotor from the hub.
Install New Rotor:
- Place the new rotor onto the hub and secure with bolts.
Reassemble Brake System:
- Reattach the caliper bracket and caliper, then reinstall the wheel.
