Affected Component

Brakes

Estimated Time

2-4 hours

⚠️ Safety Warnings

Important safety information - read before proceeding

•Always ensure the vehicle is securely supported on jack stands before working underneath.
•Allow brake components to cool before handling if the vehicle has been driven recently.

Symptoms

•Brake pedal vibrates during braking
•Unusual noise (grinding or squeaking) when braking
•Uneven braking performance
•Vehicle pulls to one side while braking
•Increased stopping distance

Diagnostic Steps

1
Inspect brake rotors for warping using a dial indicator.
2
Check brake pads for wear and even contact with rotors.
3
Examine brake calipers for proper operation and any sticking.
4
Inspect wheel bearings for play or damage.
5
Verify brake fluid level and condition; check for contamination.
6
Test drive the vehicle to replicate the pulsation and identify severity.

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
✓Check for any error codes or warning lights
✓Monitor the vehicle for a few days to ensure the issue does not recur

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety glasses and gloves.

2. Remove the Wheel

Tools Required: Jack, jack stands, lug wrench.
Loosen the lug nuts slightly before lifting the vehicle.
Use the jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually inspect the brake rotors for signs of warping or surface irregularities.
Check brake pads for even wear; replace if below specifications (usually 3mm thickness).
Inspect calipers for proper movement; ensure pistons are not seized.

4. Resurface or Replace Brake Rotors

If rotors are warped, use a brake lathe to resurface them to manufacturer specifications (usually within 0.0015 inches).
If rotors are excessively worn or damaged, replace with new rotors.
Parts Required: New brake rotors (if replacement is necessary).

5. Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Install new brake pads ensuring proper orientation and fit.
Parts Required: New brake pads.

6. Reassemble and Reinstall Wheel

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and then torque the lug nuts to the manufacturer's specifications (usually around 100-130 ft-lbs for Ram 1500).

7. Final Check

Pump the brake pedal several times to ensure proper engagement of the brakes.
Check for any fluid leaks around the calipers.
