my Ram 1500 DT (2019-Present) rear brakes are grinding, how do I fix this?

Solution

1. Preparation

• Tools Required: Socket set, torque wrench, jack and jack stands, brake cleaner, wire brush, and safety glasses.
• Ensure the vehicle is parked on a level surface with the parking brake engaged.
• Loosen the rear wheel lug nuts slightly before lifting the vehicle.

2. Raise the Vehicle

• Use a jack to lift the rear of the vehicle and secure it with jack stands.
• Remove the rear wheels to access the brakes.

3. Remove Brake Components

• Brake Pads:
  • Remove the caliper mounting bolts using a socket.
  • Carefully slide the caliper off the brake rotor.
  • Remove the old brake pads from the caliper brackets.
• Brake Rotor:
  • If necessary, remove the rotor by unscrewing any retaining screws and sliding it off the hub.

4. Inspect and Replace Components

• Brake Pads:
  • Compare the thickness of the old pads to new ones; replace if worn down (less than 3mm).
• Brake Rotor:
  • Inspect for deep grooves or warping. Replace if damaged.
• Calipers and Hardware:
  • Ensure calipers are functioning correctly. Replace if leaking or damaged.
  • Clean and inspect brake hardware; replace if worn.

5. Reassemble Brakes

• Install new brake pads into the caliper brackets.
• Slide the rotor back onto the hub.
• Reattach the caliper over the new pads and torque the mounting bolts to manufacturer specifications (generally around 25-35 ft-lbs).

6. Reinstall Wheels

• Place the wheels back onto the hubs and hand-tighten the lug nuts.
• Lower the vehicle and torque the lug nuts to specifications (typically around 100-120 ft-lbs).

7. Final Checks

• Pump the brake pedal a few times to ensure proper pad seating.
• Check brake fluid levels and top up if necessary.
