Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery when working on electrical components.
•Allow brakes to cool before working on them to avoid burns.

Symptoms

•Steering wheel vibrates during braking
•Pulsation felt in brake pedal
•Vehicle pulls to one side while braking
•Increased stopping distance
•Uneven brake pad wear

Diagnostic Steps

1
Inspect brake rotors for warping or uneven wear using a dial indicator.
2
Check brake pads for thickness and even wear; replace if worn unevenly.
3
Examine brake calipers for proper operation and sticking.
4
Inspect suspension components (ball joints, tie rods, etc.) for wear or damage.
5
Verify tire condition and balance; check for flat spots or uneven wear.
6
Test drive the vehicle to replicate the shaking and further assess the braking performance.

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:

✓Test the affected component to ensure it functions correctly

Solution

1. Preparation

Gather necessary tools and parts. Ensure the vehicle is parked on a level surface and the parking brake is engaged.
Tools Required: Jack and jack stands, lug wrench, dial indicator, torque wrench, replacement brake pads, brake rotors (if needed).

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Jack the vehicle up and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Rotors

Use a dial indicator to check for rotor runout. If runout exceeds manufacturer specifications, replace the rotors.
If replacing rotors, remove the caliper by unbolting it from the bracket and support it without stressing the brake line.
Remove the rotor from the hub; replace with a new rotor, ensuring it is properly seated.
Reinstall the caliper.

4. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Compress the caliper piston using a brake tool or C-clamp to make room for the new pads.
Install new brake pads, ensuring they are oriented correctly in the caliper bracket.

5. Reassemble and Torque

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and use a torque wrench to tighten lug nuts to the manufacturer’s specifications.

6. Test the Brakes

Start the vehicle and pump the brake pedal a few times to ensure the caliper pistons are properly seated.
Test drive the vehicle to confirm that the shaking during braking has been resolved.
