⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on electrical components.
•Allow brakes to cool before touching to avoid burns.

Symptoms

•Uneven brake pad wear
•Vehicle pulling to one side during braking
•Brake pedal feeling spongy or unresponsive
•Increased brake temperature or burning smell
•Noise from the wheel area (squealing or grinding)

Diagnostic Steps

1
Perform a visual inspection of the brake calipers for any signs of corrosion or damage.
2
Check brake pads for uneven wear patterns between the inner and outer pads.
3
Spin the wheel by hand to assess any resistance or dragging sensation.
4
Use an infrared thermometer to measure the temperature of the calipers after driving; a significantly higher temperature indicates sticking.
5
Inspect the brake lines for any signs of leaks or damage that could affect caliper function.

Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and secure with wheel chocks.
Disconnect the negative battery terminal to avoid electrical issues.

2. Lift the Vehicle

Use a jack to lift the front or rear of the vehicle, depending on which caliper is suspected to be sticking.
Secure the vehicle on jack stands for safety.

3. Remove the Wheel

Use a socket set to remove the lug nuts and take off the wheel.

4. Inspect and Clean the Caliper

Check the caliper for any physical damage or signs of sticking.
If necessary, clean the caliper slide pins using brake cleaner and a wire brush, ensuring they move freely.

5. Replace Brake Pads (if needed)

Remove the caliper bolts with a socket set.
Slide the caliper off the brake rotor and support it with a bungee cord or rope (do not let it hang from the brake line).
Remove the old brake pads and replace them with new ones if they show uneven wear.

6. Reassemble

Reattach the caliper over the new pads, ensuring it is aligned correctly.
Torque the caliper bolts to the manufacturer’s specifications (usually around 20-25 ft-lbs).
Reinstall the wheel and lug nuts, tightening them in a star pattern to ensure even pressure.

7. Lower the Vehicle

Carefully remove the jack stands and lower the vehicle back to the ground.
Reconnect the negative battery terminal.
