⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath.
•Allow brake components to cool down before handling.

Symptoms

•Pulsation felt in the brake pedal during braking
•Increased stopping distance
•Vibration in the steering wheel when braking
•Noise such as grinding or squeaking when brakes are applied
•Uneven wear on brake pads

Diagnostic Steps

1
Inspect brake rotor surfaces for warping or uneven wear using a runout gauge.
2
Check brake pads for thickness and even wear; replace if worn unevenly.
3
Measure rotor thickness with a caliper to ensure they are within specifications.
4
Examine caliper operation for sticking or binding.
5
Inspect brake lines and fluid for leaks or contamination.

2
Check brake pads for thickness and even wear; replace if worn unevenly.
3
Measure rotor thickness with a caliper to ensure they are within specifications.
4

Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is on a level surface, and engage the parking brake.
Disconnect the battery to prevent electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket set and take off the wheel.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts with a socket set.
- Tool Required: Socket set
Slide the caliper off and support it with a bungee cord to prevent strain on the brake line.
Remove old brake pads from the caliper bracket.
Install new brake pads, ensuring they are seated correctly in the caliper bracket.

4. Replace or Resurface Rotors

Remove the caliper bracket to access the rotor using a socket set.
Check rotor thickness and condition; if warped, replace or resurface.
- Parts Required: New rotors (if necessary)
Install new or resurfaced rotors onto the hub.

5. Reassemble Braking Components

Reattach the caliper bracket and torque bolts to manufacturer specifications (usually around 25-35 ft-lbs).
Reattach the caliper over the new pads and torque caliper bolts.
Reinstall the wheel and torque lug nuts in a crisscross pattern to the manufacturer's specifications.

6. Final Checks

Reconnect the battery.
Pump the brake pedal to ensure proper engagement before driving.
