⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under the vehicle.
•Allow the brakes to cool before working on them as they can be very hot after driving.

Symptoms

•Brake pedal feels spongy or soft
•Vehicle pulls to one side during braking
•Unusual noise from the wheel area when braking
•Increased brake pad wear on one side
•Wheel becomes hot to the touch after driving
•Activation of the brake warning light on the dashboard

Diagnostic Steps

1
Inspect brake fluid levels and condition in the master cylinder reservoir.
2
Check for physical damage or corrosion on the brake lines leading to the caliper.
3
Remove the wheel and visually inspect the caliper for signs of sticking or damage.
4
Test the caliper’s movement by manually compressing and releasing the caliper piston using a C-clamp.
5
Check the brake pads for uneven wear patterns.
6
Verify the condition and operation of the brake hardware (slides, pins, etc.).

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 tools and parts needed for the repair.
Park the vehicle on a flat surface, engage the parking brake, and place wheel chocks behind the rear wheels.
Disconnect the negative battery terminal to prevent electrical issues.

2. Remove the Wheel

Using a lug wrench, loosen the lug nuts on the affected wheel.
Raise the vehicle with a jack and secure it with jack stands.
Fully remove the lug nuts and take off the wheel.

3. Remove the Caliper

Locate the caliper mounting bolts (usually two) and remove them using a socket wrench.
Carefully slide the caliper off the brake rotor. If the caliper is stuck, gently tap it with a rubber mallet to loosen it.
Support the caliper with a bungee cord or rope to avoid stress on the brake line.

4. Inspect and Clean

Inspect the caliper piston and housing for damage or corrosion.
Clean the caliper slides and pins with brake cleaner and a wire brush to remove any debris or rust.
Apply brake grease to the slides and pins to ensure smooth movement.

5. Replace or Rebuild Caliper (if necessary)

If the caliper is damaged, replace it with a new or remanufactured caliper.
If rebuilding, replace the caliper piston and seals as per manufacturer specifications.
Ensure all components are properly lubricated before reassembly.

6. Reinstall the Caliper and Wheel

Slide the caliper back onto the rotor and align it with the mounting holes.
Reinsert and tighten the caliper mounting bolts to the manufacturer's torque specifications (typically around 20-25 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and use a torque wrench to tighten the lug nuts to the specified torque (usually 76-83 ft-lbs).
