⚠️ Safety Warnings

Important safety information - read before proceeding

•Allow the vehicle to cool before working on the brake system.
•Always wear safety glasses and gloves when handling brake components and fluids.

Symptoms

•Vehicle pulls to one side during braking
•Increased brake pedal travel or sponginess
•Overheating of wheels or brake components
•Squeaking or grinding noises from the brakes
•Uneven wear on brake pads
•Burning smell from the brakes after driving

Diagnostic Steps

1
Inspect brake pads for uneven wear patterns indicating caliper issues.
2
Check the temperature of the brake rotors after a short drive; a significantly hotter rotor suggests a sticking caliper.
3
Test the brake pedal feel; excessive travel or sponginess may indicate caliper issues.
4
Visually inspect the caliper for signs of fluid leaks or physical damage.
5
Perform a brake system test by applying pressure and observing if the wheels release properly.

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

After completing the repair, verify that the issue has been resolved:

✓Test the affected component to ensure it functions correctly
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Prevention Tips

Solution

1. Preparation

Gather tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to prevent movement.
Disconnect the battery to ensure safety.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts while the vehicle is on the ground.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts and wheel.

3. Inspect and Clean Caliper

Visually inspect the caliper for damage or corrosion.
Use brake cleaner to clean the caliper, paying attention to the piston and sliding surfaces.
Ensure that the caliper slides freely on its pins; lubricate with high-temperature brake grease if needed.

4. Replace Caliper (if necessary)

If the caliper is damaged or not functioning properly, remove the caliper by unscrewing the mounting bolts.
Disconnect the brake line from the caliper using a line wrench, and be prepared for brake fluid to leak.
Install a new or remanufactured caliper, ensuring to use new copper washers on the brake line connection.
Tighten the brake line connection to the manufacturer's specifications, and torque the caliper mounting bolts to proper specs.

5. Reassemble and Test

Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a star pattern.
Reconnect the battery and perform a brake system test to ensure proper function.
