⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on brake systems to avoid electric shock or airbag deployment.
•Allow brake components to cool before handling to prevent burns.

Symptoms

•Brake pedal feels stiff or unresponsive
•Vehicle pulls to one side during braking
•Increased brake noise (squeaking or grinding)
•Brake pads show uneven wear
•Overheating of the wheel or brake assembly
•Warning light illuminated on the dashboard

Diagnostic Steps

1
Inspect the brake pedal feel and response during operation.
2
Check for any visible signs of brake fluid leaks around the caliper.
3
Remove the wheel and visually inspect the caliper for damage or corrosion.
4
Check the condition of the brake pads for uneven wear patterns.
5
Test the caliper by attempting to compress the piston using a C-clamp.
6
Inspect the brake lines for kinks or blockages that could restrict fluid flow.

Solution

Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is turned off.
Wear safety goggles and gloves.
Jack up the vehicle and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel lug nuts.
Take off the wheel to access the brake assembly.

3. Remove Caliper

Locate the caliper mounting bolts using a socket set.
Remove the caliper mounting bolts and carefully slide the caliper off the brake rotor.
Support the caliper using a bungee cord or rope to avoid stressing the brake line.

4. Inspect and Clean

Inspect the caliper for any signs of damage, corrosion, or seized components.
Clean the caliper slide pins with brake cleaner and a rag; lubricate with high-temperature brake grease if necessary.
Check the piston for movement; if stuck, proceed to the next step.

5. Replace Caliper or Piston (if necessary)

If the piston is stuck, replace the caliper with a new or rebuilt unit.
For a piston replacement, use a caliper rebuild kit and follow the manufacturer's instructions for assembly.
Ensure all seals are properly installed to prevent leaks.

6. Reassemble

Position the caliper back onto the brake rotor.
Reinstall the caliper mounting bolts and torque them to the manufacturer's specifications (typically around 20-30 ft-lbs).
Reinstall the wheel and tighten lug nuts in a criss-cross pattern.

7. Final Check

Refill brake fluid if necessary and bleed the brake system to remove any air.
Ensure all tools are removed from the work area.
