Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

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

Symptoms

•Strong vibration felt through the brake pedal and steering wheel
•Unusual noise (grinding or squeaking) during braking
•Reduced braking efficiency
•Possible pulling to one side during braking
•Vibration present at various speeds, especially noticeable at higher speeds

Diagnostic Steps

1
Inspect brake pads for wear and uneven surfaces using a visual inspection.
2
Check rotors for warping or scoring by measuring rotor thickness and runout.
3
Examine the brake calipers for proper operation and any signs of sticking or seizing.
4
Assess the brake fluid level and condition; look for contamination or air bubbles.
5
Inspect wheel bearings and suspension components for wear or damage that could affect braking.

Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, dial indicator (for rotor measurement).
Lift the vehicle and secure it on jack stands. Ensure the parking brake is engaged.

2. Inspect and Replace Brake Pads

Remove the wheel using the lug wrench.
Inspect the brake pads; if they are worn unevenly or below the recommended thickness, replace them.
- Sub-steps:
  - Remove the caliper bolts with a socket wrench.
  - Slide off the caliper and hang it with a bungee cord (do not let it dangle by the brake line).
  - Remove the old brake pads and install new ones, ensuring they are correctly seated.
  - Reinstall the caliper and torque the bolts to manufacturer specifications.

3. Examine and Resurface/Replace Rotors

Measure the rotor thickness with a micrometer; check for warping using a dial indicator.
- Sub-steps:
  - If rotors are within service limits, consider resurfacing them. Clean with brake cleaner before reinstalling.
  - If rotors are out of spec, replace them with new ones.
  - Install new rotors, ensuring proper alignment and torque bolts to specifications.

4. Check Brake Calipers

Inspect calipers for proper function.
- Sub-steps:
  - Clean and lubricate any sliding pins.
  - Replace calipers if they are found to be faulty or sticking.

5. Final Assembly and Testing

Reinstall the wheel and lower the vehicle.
Torque the lug nuts to the manufacturer's specifications.
Pump the brake pedal to ensure proper seating of the pads before road testing.
