Diagnostic Steps

Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface with the parking brake engaged.
Use wheel chocks to prevent movement.
Disconnect the negative battery terminal for safety.

Tools Required:

Jack and jack stands
Lug wrench
Brake caliper tool
Torque wrench
Brake cleaner
Brake grease
Socket set and ratchet

2. Remove the Wheel

Loosen lug nuts with a lug wrench while the vehicle is still on the ground.
Raise the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Remove the Brake Caliper

Locate the caliper mounting bolts and remove them using the socket set.
Carefully slide the caliper off the rotor. Support it using a bungee cord or rope to avoid straining the brake line.
Inspect the caliper for any visible damage or rust.

4. Clean and Inspect Components

Use brake cleaner to clean the caliper, rotor, and brake pads.
Inspect the caliper slide pins; they should move freely. If they are sticky, remove them, clean, and apply fresh brake grease.
Check the condition of the brake pads; replace if worn unevenly.

5. Rebuild or Replace the Caliper

If the caliper is sticking due to a seized piston, rebuild it using a caliper rebuild kit or replace the caliper if severely damaged.
For rebuilding, remove the old seals and install new ones according to the kit instructions.

6. Reassemble the Brake System

Reattach the caliper to the rotor, ensuring it is properly seated.
Tighten the caliper mounting bolts to the manufacturer's specified torque (typically around 25-30 ft-lbs).
Reinstall the wheel and tighten the lug nuts in a crisscross pattern to ensure even seating.

7. Final Checks

Lower the vehicle and reconnect the negative battery terminal.
Pump the brake pedal to restore caliper pressure.
Test the brakes at low speed to ensure they function correctly.
