Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical components.
•Allow the brakes to cool before performing any maintenance.

Symptoms

•Pulsating or vibrating sensation in the brake pedal during braking
•Uneven wear on brake pads
•Increased stopping distance
•Brake noise such as grinding or squeaking
•Steering wheel vibration when braking

Diagnostic Steps

1
Inspect the brake rotors for warping or uneven surfaces using a dial indicator.
2
Check the brake pads for wear and thickness; replace if worn beyond manufacturer specifications.
3
Examine brake calipers for proper operation and ensure they are not sticking.
4
Verify wheel bearings for play or damage that could affect braking.
5
Inspect suspension components for wear or damage that may contribute to brake pulsation.

Solution

💡 Expert Tip

For complex repairs like this, consider taking photos at each step. This helps if you need to reverse a step or consult with a mechanic. Also, keep all removed parts organized - you may need to reference them during reassembly.

Verification

After completing the repair, verify that the issue has been resolved:

Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, dial indicator, brake cleaner, and a torque spec chart.
Safely lift the vehicle and remove the wheels.
Ensure the vehicle is on a stable surface and securely supported.

2. Inspect and Measure Brake Rotors

Use a dial indicator to measure rotor runout.
- Sub-steps:
  - Mount the dial indicator to the brake caliper bracket.
  - Rotate the rotor slowly and record the maximum deviation.
  - If runout exceeds the manufacturer's specifications (usually around 0.002-0.004 inches), the rotor may need resurfacing or replacement.

3. Replace or Resurface Brake Rotors

If the rotors are warped, either resurface or replace them.
- Sub-steps:
  - If resurfacing, follow the shop's specifications for machining.
  - For replacement, remove the retaining screws (if applicable) and slide off the rotor.
  - Install the new or resurfaced rotor, ensuring proper seating.

4. Replace Brake Pads

Replace brake pads if they are worn.
- Sub-steps:
  - Remove the caliper bolts using a socket set.
  - Slide the caliper off the rotor and support it with a bungee cord (do not let it hang from the brake line).
  - Remove old pads and install new pads, ensuring they are properly positioned in the caliper bracket.
  - Reinstall the caliper over the new pads and tighten the bolts to manufacturer specifications.

5. Reassemble and Test

Reinstall the wheel and lower the vehicle.
Sub-steps:
- Torque the wheel lug nuts to the manufacturer-recommended specifications.
- Pump the brake pedal to ensure proper pad seating.
- Test drive the vehicle at low speeds to confirm the pulsation issue is resolved.
