•Allow the brakes to cool before servicing to prevent burns.

Symptoms

•Brake warning light illuminated on the dashboard
•Uneven brake wear on the brake pads
•Vehicle pulls to one side during braking
•Squeaking or grinding noise when brakes are applied
•Brake pedal feels spongy or has excessive travel
•Brake fluid leaks near the caliper assembly

Diagnostic Steps

1
Inspect the brake pads for uneven wear and thickness.
2
Check the brake fluid level in the master cylinder reservoir.
3
Visually inspect the brake caliper for signs of fluid leaks.
4
Use a brake pad thickness gauge to measure pad wear.
5
Perform a brake system test by applying the brakes and observing for pulling or noise.
6
Check the caliper movement by attempting to compress the caliper piston using a C-clamp.

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.

Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and safety equipment (gloves, goggles).
Loosen the lug nuts on the wheel with the affected brake caliper.

2. Lift the Vehicle

Use a jack to raise the vehicle and secure it with jack stands.
Remove the wheel to access the brake caliper.

3. Inspect and Clean

Visually inspect the brake caliper for any signs of damage or leaking fluid.
Clean the caliper and surrounding area with brake cleaner to ensure a clear view of any issues.

4. Check Brake Pads

Remove the caliper bolts using a socket wrench and carefully slide the caliper off the rotor.
Inspect the brake pads for wear; replace if thickness is below the manufacturer's specifications (usually around 3mm).
If the pads are worn unevenly, check the caliper slide pins for proper lubrication and function.

5. Caliper Functionality Test

Press the brake pedal to extend the caliper piston slightly.
Use a C-clamp to compress the piston back into the caliper housing, ensuring it moves smoothly without resistance.
If the piston is seized, the caliper will need to be replaced.

6. Reassemble

Reinstall the caliper over the new or inspected brake pads.
Torque the caliper bolts to the manufacturer's specifications (usually around 25-35 Nm).
Reattach the wheel and lower the vehicle.
Tighten the lug nuts to the appropriate torque specification (usually around 100 Nm).
