Important safety information - read before proceeding

•Always disconnect the battery before working on the brake system.
•Allow the brakes to cool before handling to avoid burns.

Symptoms

•Reduced braking efficiency
•Brake pedal feels spongy or unresponsive
•Grinding noise when braking
•Uneven brake pad wear
•Vehicle pulls to one side during braking
•Wheel overheating or excessive heat from brake components

Diagnostic Steps

1
Inspect the brake fluid level and condition in the master cylinder reservoir.
2
Check for any visible damage or corrosion on the brake caliper and mounting hardware.
3
Remove the wheel to access the brake caliper and visually inspect the caliper movement and condition.
4
Test the caliper's operation by manually compressing the caliper piston with a C-clamp or caliper tool.
5
Examine the brake line for kinks or blockages that may restrict fluid flow.
6
Scan for any ABS or brake-related fault codes using an OBD-II scanner.

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface, and set the parking brake.
Wear safety glasses and gloves for protection.

2. Remove the Wheel

Use a lug wrench to loosen the lug nuts on the wheel.
Lift the vehicle using a jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake caliper.

3. Remove the Brake Caliper

Locate the caliper mounting bolts (usually two) and remove them using a socket wrench.
Carefully slide the caliper off the rotor. Do not let the caliper hang by the brake line; support it with a bungee cord or similar device.
Disconnect the brake line from the caliper if replacement is necessary.

4. Inspect and Repair the Caliper

Check the caliper piston for corrosion or damage. If it's stuck, try using a caliper tool to compress and then extend it to free it up.
If the caliper is beyond repair, replace it with a new or rebuilt unit.
Clean the caliper bracket and ensure the guide pins move freely. Lubricate them with high-temperature brake grease.

5. Reinstall the Caliper and Wheel

If the caliper was replaced, connect the brake line and torque the fittings to manufacturer specifications (typically around 12-15 ft-lbs).
Slide the caliper back onto the rotor and secure it with the mounting bolts, torquing them to the manufacturer's specifications (usually around 20-25 ft-lbs).
Reinstall the wheel, hand-tighten the lug nuts, lower the vehicle, and torque the lug nuts to manufacturer specifications (typically around 100-150 ft-lbs).

6. Final Checks

Pump the brake pedal several times to ensure proper brake pressure builds up.
Check the brake fluid level again and top off if necessary.
Test the brakes in a safe area to ensure proper function.
