1-2 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under a vehicle.
•Ensure the vehicle is in gear or in "Park" before lifting.

Symptoms

•Unusual squeaking or grinding noises during braking
•Reduced braking performance or responsiveness
•Vibration or pulsation in the brake pedal

•Increased stopping distance

Diagnostic Steps

1
Inspect brake pads visually for thickness and wear indicators.
2
Measure the remaining pad thickness using a micrometer.
3
Check for any signs of uneven wear or damage on the brake rotor.
4
Look for any brake fluid leaks at calipers or lines.
5
Test brake performance during a short drive to assess functionality.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent accidental brake activation.

2. Remove Wheel

Loosen lug nuts with a socket wrench.
Lift the vehicle using a jack and secure it with jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Locate the brake caliper and inspect it for any damage or leaks.
Measure the brake pad thickness; pads should typically be replaced when they reach about 3 mm.

4. Replace Brake Pads

Unscrew the caliper bolts using a socket wrench.
Carefully slide the caliper off the rotor and hang it using a wire to avoid stress on the brake line.
Remove old brake pads from the caliper bracket.
Install new brake pads into the caliper bracket, ensuring proper alignment.
Compress the caliper piston using a brake caliper tool to allow for new pads.

5. Reassemble Components

Reattach the caliper over the new brake pads and secure it with caliper bolts. Torque the bolts to the manufacturer's specifications.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern.

6. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to seat the pads properly.
Test drive the vehicle at low speeds to ensure proper braking function.
