This procedure covers the removal and replacement of both front brake rotors on a 2014 Ram 2500 with 6.7L Cummins Diesel, including caliper bracket removal and proper torque specifications.

Warnings

Tools required

Parts

• Front brake rotor × 2 — Use OEM specification or quality aftermarket equivalent
• Rotor set screws (if corroded) × 2 — M6 x 10mm Torx set screws

Fluids

• Mopar DOT 4 Brake Fluid — 0.25 qt

Preparation

1. Park vehicle on level, solid surface and engage parking brake.
2. Place wheel chocks behind rear wheels.
3. Loosen front wheel lug nuts 1/4 turn while vehicle is on ground.
4. Lift front of vehicle using floor jack at manufacturer-specified lift points on frame.
5. Place jack stands under frame rails on both sides. Lower vehicle onto stands with wheels still off ground.
6. Remove front wheels completely and set aside.
7. Inspect brake system for leaks, damaged hoses, or other issues before proceeding.
8. Have a drain pan ready in case any brake fluid spills during caliper repositioning.

Procedure

1. 1

   Clean and prepare rotor set screws
   Spray penetrating oil on the rotor set screws (Torx screws holding rotor to hub). Allow to penetrate for 5-10 minutes. These screws are often severely corroded on trucks and may require significant force or heat to remove. Clean the Torx head completely to ensure proper bit engagement.
2. 2

   Remove caliper slide pin bolts
   Using an 18mm socket, remove the two caliper slide pin bolts from the rear of the caliper. These bolts pass through rubber bushings and secure the caliper to the bracket. Support the caliper while removing the second bolt. Do not let the caliper fall or hang by the brake hose.
   ⚠Support the caliper before removing the second bolt to prevent it from falling and damaging the brake hose.

   Secure caliper out of the way
   Carefully lift the caliper up and off the rotor. Do NOT allow it to hang by the brake hose. Use wire, a bungee cord, or a hook to suspend the caliper from the suspension or frame. Ensure the brake hose has no tension or kinks. If needed, use a C-clamp to gently compress the caliper piston slightly to provide clearance.
   ⚠️Never allow the caliper to hang unsupported by the brake hose. This can cause internal damage leading to brake failure.
4. 4

   Remove caliper bracket bolts
   Using an 18mm socket and breaker bar, remove the two caliper bracket bolts. These are large bolts torqued to high specification and will require significant force. The bracket bolts thread into the steering knuckle. Remove the entire caliper bracket assembly and set aside. Inspect bracket slide surfaces for wear or damage.
   ⚠These bolts are torqued to 101 lb-ft and may require a breaker bar or impact tool to remove.

   Remove rotor set screws
   Using a T55 Torx bit, remove the rotor set screw(s) holding the rotor to the hub. Apply firm downward pressure while turning to prevent stripping. If screws are severely corroded or stripped, they may be drilled out or cut off - they are only for assembly and not required for reinstallation if necessary. Most 2014 Ram 2500 models have one set screw per rotor.
   ⚠Set screws are often corroded and may strip. Apply firm pressure and use a quality Torx bit. Penetrating oil may be needed.

6. 6

   Remove brake rotor
   Pull the rotor straight off the hub. The rotor may be seized to the hub by corrosion. If stuck, strike the rotor from behind (between the wheel studs) with a dead blow hammer or rubber mallet. Rotate the rotor and strike in multiple locations. Do NOT strike the rotor friction surface or the hub bearing area. If severely stuck, apply penetrating oil around the hub center and allow to soak, then use a two-jaw puller or continue with mallet strikes.
   ⚠Do not strike the hub bearing assembly or rotor mounting flange with a metal hammer as this can damage wheel bearings.
7. 7

   Clean hub mounting surface
   Using a wire brush and brake parts cleaner, thoroughly clean the hub mounting surface where the rotor seats. Remove all rust, corrosion, and debris. The surface must be clean and flat for proper rotor seating. Clean the wheel studs and surrounding area. Inspect hub for any damage, excessive play, or leaking grease which would indicate bearing issues.
8. 8

   Install new brake rotor
   Remove any protective coating from the new rotor using brake parts cleaner (both sides). Place the new rotor onto the hub, aligning the holes for the set screw. Ensure the rotor sits flush against the hub face with no debris preventing full contact. Install the set screw(s) and torque to specification. The set screw only holds the rotor during assembly; the wheel and lug nuts provide the clamping force during operation.
   ℹ️New rotors have a protective oil coating that must be removed with brake cleaner before installation to prevent brake contamination.

   Reinstall caliper bracket
   Clean the caliper bracket bolt threads and holes in the knuckle with a wire brush. Apply thread locker to the bracket bolts if recommended. Position the caliper bracket over the rotor and align the bolt holes with the steering knuckle. Start both bolts by hand to ensure proper thread engagement. Torque the caliper bracket bolts to specification using a torque wrench.
   ⚠Cross-threading these high-torque bolts can damage the steering knuckle threads, requiring expensive replacement.

    Prepare caliper and slide pins
    Before reinstalling the caliper, inspect the slide pin boots for tears or damage. Clean the slide pins and apply fresh silicone brake grease to the pins. Ensure the pins move freely in their bores. If the caliper piston is extended, use a C-clamp or piston tool to compress it back into the caliper bore to provide clearance for the new (thicker) rotor. Push slowly and watch the master cylinder reservoir - fluid level will rise.
    ⚠When compressing caliper pistons, brake fluid level in master cylinder will rise. Check reservoir and remove fluid if necessary to prevent overflow.
11. 11

    Reinstall brake caliper
    Position the caliper over the rotor and align the slide pin bolt holes with the bracket. Ensure the brake pads are properly seated on each side of the rotor. Install both caliper slide pin bolts and torque to specification. Apply silicone brake grease to the slide pin bolt threads and contact surfaces as specified.
    ⚠Ensure brake pads are properly positioned on both sides of rotor before tightening bolts.

    Repeat for opposite side
    Repeat steps 1 through 11 for the opposite front rotor. Ensure both sides are completed with all fasteners properly torqued before proceeding to wheel installation.
13. 13

    Reinstall wheels
    Clean the wheel mounting surfaces on the rotors. Install wheels and start all lug nuts by hand. Lower the vehicle until the wheels just contact the ground (still supported partially by jack stands). Torque the lug nuts to specification in a star pattern. Fully lower the vehicle and remove jack stands. Perform a final torque check on all lug nuts in star pattern with vehicle on ground.
    ⚠Always torque lug nuts in a star pattern to ensure even clamping force and prevent rotor warping.

    Pump brake pedal and check fluid
    Before moving the vehicle, pump the brake pedal several times until it feels firm. The first few pumps will feel soft as the caliper pistons extend to contact the new rotors. Check the brake fluid level in the master cylinder reservoir and top off with Mopar DOT 4 brake fluid if necessary. The level should be between MIN and MAX marks.
    ⚠️CRITICAL: The brake pedal will go to the floor if you attempt to move the vehicle before pumping up the brakes. Always pump the pedal until firm before driving.

Reassembly

1. Ensure all fasteners are torqued to specification, particularly the safety-critical caliper bracket bolts and wheel lug nuts.
2. Verify brake pedal is firm before attempting to move vehicle.
3. Check for any brake fluid leaks around caliper connections.
4. Verify all tools and parts have been removed from wheel wells and under vehicle.

Verification

• Pump brake pedal until firm - pedal should not travel more than halfway to floor with firm pressure.
• Check brake fluid level in master cylinder - should be between MIN and MAX marks.
• Start engine and pump brakes several times. Pedal should remain firm.
• Perform low-speed brake test in a safe area. Brakes should engage smoothly without pulling to one side.
• Perform bed-in procedure: Make 8-10 stops from 40 mph to 15 mph with moderate brake pressure, allowing 30 seconds between stops to cool. This transfers material to the rotor surface and ensures proper brake performance.
• After first 50-100 miles, re-torque wheel lug nuts to specification.
• Expect reduced braking performance and possible noise during the first 200-300 miles as rotors and pads mate.
• Listen for any unusual noises (grinding, squealing, rubbing) which may indicate improper installation or debris.
• Verify vehicle stops straight without pulling left or right, which could indicate uneven brake application.
