Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the braking system.
•Allow brake components to cool before handling after driving.

Symptoms

•Uneven thickness of brake pads on one side compared to the other
•Increased noise from brakes during operation
•Vibration or pulsation felt in the brake pedal
•Vehicle pulling to one side during braking
•Reduced braking efficiency or longer stopping distances
•Visual inspection revealing brake dust accumulation on one wheel more than the other

Diagnostic Steps

1
Inspect brake pads visually for uneven wear patterns.
2
Measure the thickness of the brake pads on all four wheels using a caliper.
3
Check brake rotor condition for warping or uneven surface.
4
Examine brake caliper operation for proper movement and hydraulic function.
5
Inspect the brake lines and hoses for any restrictions or leaks.
6
Verify wheel alignment and suspension components for issues affecting brake performance.

Solution

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, caliper gauge, torque wrench, brake cleaner, safety goggles, gloves.
Lift the vehicle and secure it on jack stands.
Remove the wheels using the lug wrench.

2. Inspect and Replace Brake Pads

Remove Brake Calipers:
- Use a socket set to remove caliper mounting bolts.
- Carefully detach the caliper and support it without stretching the brake line.
Remove Brake Pads:
- Slide out the old brake pads from the caliper bracket.
- Note the orientation and condition for comparison.
Inspect Brake Rotors:
- Check for signs of warping, scoring, or excessive wear.
- If necessary, resurface or replace rotors according to specifications.

3. Replace Calipers (if necessary)

Remove Old Caliper:
- Disconnect brake line (use a container to catch fluid).
- Unbolt the caliper from the mounting bracket.
Install New Caliper:
- Position the new caliper and secure it with bolts.
- Reconnect the brake line and torque to specifications (typically around 20-30 ft-lbs).

4. Install New Brake Pads

Insert new brake pads into the caliper bracket.
Ensure they are seated correctly and match the original orientation.

5. Reassemble

Reattach Brake Calipers:
- Position the caliper over the new pads and secure it with bolts.
- Torque to manufacturer specifications (typically around 25-35 ft-lbs).
Reinstall Wheels:
- Attach the wheels and hand-tighten the lug nuts.

6. Final Checks

Lower the vehicle and torque the lug nuts to specifications (typically around 100-150 ft-lbs).
Pump the brake pedal to ensure proper caliper engagement.
