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

Symptoms

•Noticeable differences in thickness between front or rear brake pads
•Grinding or squeaking noise when brakes are applied
•Vehicle pulling to one side during braking
•Increased braking distance or reduced braking efficiency
•Vibration or pulsation in the brake pedal

Diagnostic Steps

1
Inspect brake pads visually for uneven wear patterns.
2
Measure the thickness of each brake pad using a caliper.
3
Check brake rotors for warping or uneven surface.
4
Examine brake calipers for proper function and signs of sticking or binding.
5
Inspect brake lines for leaks or damage.
6
Review suspension components for wear or misalignment issues.

Solution

Solution

1. Preparation

Gather tools and parts required.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Lift the Vehicle

Use a hydraulic jack to lift the vehicle from the designated lift points.
Secure with jack stands for safety.
Remove the wheel covering the brake assembly.

3. Inspect and Replace Brake Pads

Remove the brake caliper bolts using a socket set.
Carefully slide the caliper off the rotor and support it with a hanger (do not let it dangle from the brake line).
Remove the old brake pads from the caliper bracket.
Measure the old pads’ thickness; if less than the manufacturer’s specification, replace them.
Install new brake pads, ensuring they fit snugly into the caliper bracket.

4. Inspect Brake Rotors

Check rotors for scoring or warping using a run-out gauge.
If warped, replace or resurface rotors as necessary.
Clean the rotor surface with brake cleaner before reassembly.

5. Reassemble Brake Components

Reattach the brake caliper over the new pads.
Torque the caliper bolts to the manufacturer’s specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and lower the vehicle.
