Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always engage the parking brake before lifting the vehicle.
•Allow brake components to cool before handling if the vehicle has been driven recently.

Symptoms

•Shaking or vibration felt through the steering wheel when braking
•Pulsation in the brake pedal
•Increased stopping distance
•Uneven wear on brake pads or rotors
•Possible noise such as grinding or squeaking during braking

Diagnostic Steps

1
Inspect front and rear brake rotors for warping or surface irregularities.
2
Check the brake pad thickness and condition for uneven wear.
3
Examine suspension components, including control arms, tie rods, and bushings for wear or damage.
4
Assess wheel alignment and balance to rule out related issues.
5
Perform a visual inspection of the brake calipers to ensure they are functioning properly and not sticking.

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Loosen the lug nuts on the front wheels slightly.

2. Lift the Vehicle

Use a hydraulic jack to lift the front of the vehicle.
Secure the vehicle with jack stands.

3. Remove Wheel

Fully remove the lug nuts and take off the front wheels.

4. Inspect and Replace Brake Rotors

Inspect: Check rotors for warping using a dial indicator gauge.
Replace if warped:
- Remove the caliper mounting bolts and slide the caliper off the rotor.
- Detach the rotor from the hub (may require removing screws or clips).
- Clean the hub surface to ensure proper seating of the new rotor.
- Install new rotors, ensuring they are torqued to manufacturer specifications (typically 10-15 Nm).

5. Inspect and Replace Brake Pads

Inspect: Check for thickness and wear of brake pads.
Replace if necessary:
- Remove the old pads by sliding them out of the caliper bracket.
- Use a brake caliper tool to compress the piston back into the caliper housing.
- Insert new pads into the caliper bracket and ensure they are seated properly.

6. Reassemble Components

Reinstall the brake caliper and torque the mounting bolts to specifications (usually around 30-40 Nm).
Reattach the wheel and hand-tighten the lug nuts.
Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque (typically 100-120 Nm).

7. Test Drive

After reassembly, perform a test drive to ensure the issue is resolved.

Tools Required:
