Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working under the vehicle.
•Allow brakes to cool before working on them to avoid burns.

Symptoms

•Steering wheel vibrates or shakes during braking
•Pulsation felt through the brake pedal
•Uneven wear on brake pads
•Increased stopping distance
•Possible noise during braking (grinding or squeaking)

Diagnostic Steps

1
Inspect brake components for wear and damage, including pads, rotors, and calipers.
2
Check rotor condition for warping or thickness variation using a micrometer.
3
Verify proper wheel alignment by measuring alignment angles.
4
Examine suspension components for wear or damage (e.g., tie rods, control arms).
5
Inspect tire condition and balance; check for bulges or uneven wear.

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

Tools Required: Jack, jack stands, lug wrench, torque wrench, micrometer, brake cleaner, and safety glasses.
Ensure the vehicle is parked on a flat surface, and engage the parking brake.
Disconnect the battery if necessary for safety.

2. Inspect and Replace Brake Pads and Rotors

Lift the Vehicle: Use a jack to lift the front of the Tacoma and secure it with jack stands.
Remove Wheels: Use a lug wrench to remove the lug nuts and take off the wheels.
Inspect Brake Pads:
- Check the thickness of the brake pads; replace if less than 3mm.
- If unevenly worn, replace both pads on the affected axle.
Inspect and Replace Rotors:
- Measure rotor thickness using a micrometer; if below the minimum specification or warped, replace the rotors.
- Clean the rotor surface with brake cleaner before installation.
Install New Components:
- Install the new rotors and pads in reverse order of removal.
- Torque lug nuts to manufacturer specifications (usually around 80-100 ft-lbs).

3. Check and Adjust Wheel Alignment

Alignment Check: Use an alignment tool to measure camber, caster, and toe angles.
Adjust as Necessary: If misaligned, adjust the settings according to manufacturer specifications.

4. Inspect and Replace Suspension Components (if necessary)

Visual Inspection: Look for signs of wear on tie rods and control arms.
Replace Worn Parts: If any components are damaged, replace them following manufacturer guidelines.
