⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the braking system to prevent electrical issues.
•Allow the vehicle to cool before working on brake components to avoid burns.

Symptoms

•Uneven braking force or pulling to one side during braking
•Squeaking or grinding noise when brakes are applied
•Visible fluid leakage around the calipers
•Brake pedal feels spongy or goes to the floor
•Overheating of the brake components

Diagnostic Steps

1
Inspect the brake calipers visually for any noticeable damage or leakage of brake fluid.
2
Check the brake pads for uneven wear patterns that may indicate caliper issues.
3
Test brake performance by driving at a low speed and applying brakes to feel for pulling or noise.
4
Measure the temperature of the brake calipers after a short drive to identify any overheating issues.
5
Use a multimeter to check for electrical issues if the vehicle has electronic brake assist features.

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the car is parked on a level surface.
Use wheel chocks to prevent movement and jack stands for safety.

2. Remove Wheel

Loosen lug nuts with a tire iron.
Lift the vehicle using a hydraulic jack.
Securely place jack stands under the vehicle for safety.
Remove the wheel to access the brake calipers.

3. Inspect Brake Caliper

Check for any visible cracks, leaks, or corrosion on the caliper body.
Ensure the caliper piston moves freely by gently pressing it with a C-clamp or brake tool.
If the caliper is stuck or leaking, it will need replacement.

4. Replace Brake Caliper (if defective)

Remove the caliper mounting bolts using a socket set.
Carefully detach the caliper from the bracket while avoiding damage to brake lines.
Disconnect the brake line from the caliper using a flare wrench. Catch any fluid in a container.
Install the new caliper by reversing the disconnection steps and ensure the brake line is secured properly.
Torque the caliper mounting bolts to the manufacturer’s specifications (typically around 25-30 Nm).

5. Reassemble Components

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (around 100 Nm).
Recheck the brake fluid level and top off if necessary.
