2019 Ram 2500 Brake Pad & Rotor Specifications

As an ASE-certified master technician, I’ve serviced countless heavy-duty trucks. The 2019 Ram 2500 is an absolute powerhouse designed for serious towing and hauling, which means its braking system takes a tremendous beating. Whether you're doing a routine pad-slap or a complete brake overhaul, getting the specifications right is critical for your safety and the longevity of your truck.

Below is the definitive brake specification guide for the 2019 Ram 2500 to help you get the job done right.

Quick reference

(Note: Always verify exact torque specifications and part numbers with your local Ram dealer or a factory service manual, as specs can vary slightly based on specific trim levels and axle configurations.)

How to choose pads

When selecting brake pads for a 3/4-ton truck like the 2019 Ram 2500, your choice of friction material will dictate your stopping power, dust levels, and noise.

• Heavy-Duty (HD) / Severe Duty: If you regularly tow a fifth-wheel, haul heavy payload, or drive in mountainous terrain, you need heavy-duty pads. Formulations like the Power Stop Z36 Truck & Tow or Wagner SevereDuty offer a high-temperature threshold to prevent brake fade. These are highly recommended for the Ram 2500.
• Semi-Metallic: These pads offer excellent cold bite and dissipate heat very effectively. They are incredibly durable and great for towing, but they tend to be noisier and generate significantly more brake dust than other materials.
• Ceramic: If your Ram 2500 is primarily a daily driver or a "pavement princess" that rarely sees heavy loads, ceramic pads (like Akebono ProACT or Bosch QuietCast) are an excellent choice. They are quiet, produce very little dust, and are gentle on the rotors. However, they do not dissipate heat as well under extreme towing conditions.

Typical service life

Because the Ram 2500 is a heavy vehicle—often weighing north of 7,000 lbs empty—brake wear is highly dependent on how the truck is used.

For a daily driver seeing mixed highway and city driving with occasional light hauling, front brake pads typically last between 40,000 and 60,000 miles. Rear pads often last slightly longer, usually needing replacement around 50,000 to 70,000 miles.

However, if you are hot-shotting or regularly hauling heavy construction equipment, you may burn through a set of front pads in as little as 25,000 miles.

Recommended pad-slap interval: A "pad-slap" (replacing just the brake pads and leaving the old rotors) is generally only recommended if the rotors are well above the minimum discard thickness, have no deep grooves, and show no signs of lateral runout (warping). For the Ram 2500, I recommend turning or replacing the rotors every time you change the pads to ensure maximum stopping power. If you must pad-slap, only do it once per rotor lifecycle, and never exceed the minimum discard thickness of 36.0mm (front) or 32.0mm (rear).

Common brake issues for this generation

The 2019 Ram 2500 (part of the 5th generation/updated 4th-gen heavy-duty chassis) is a robust truck, but it does have a few quirks when it comes to the braking system:

1. Rotor Warping Under Load: The massive weight of the truck combined with heavy towing can lead to excessive heat buildup. If the driver relies too heavily on the service brakes instead of the exhaust brake (if equipped with the Cummins diesel), the rotors can overheat and warp, leading to a severe steering wheel shake when braking.
2. Seized Caliper Slide Pins: The dual-piston calipers use robust slide pins, but the rubber boots can tear, allowing water and road salt to enter. This causes the pins to seize, leading to uneven pad wear and dragged brakes. Always clean and generously lubricate the slide pins with high-temp silicone brake grease during a brake job.
3. Spongy Pedal Feel: If you boil the brake fluid on a steep descent, you'll introduce moisture and air into the system. Upgrading to a high-quality DOT 4 fluid and flushing the system every 2 to 3 years will keep the pedal feeling firm.

Brake job cost estimate

If you are tackling this job in your driveway, you can save a significant amount of money. Expect to spend the following on parts:

• DIY Parts Cost: High-quality aftermarket pads and rotors for the front will run you about $200 to $350. A complete four-wheel pad and rotor kit (like a Power Stop Z36 kit) typically costs between $450 and $600.
• Professional Shop Cost: If you take your Ram 2500 to a dealership or an independent shop, labor rates and part markups apply. Expect to pay between $400 and $600 per axle for pads and rotors. A complete four-wheel brake job will generally set you back $800 to $1,200, depending on your location and the quality of parts used.

Brakes are the most critical safety system on a heavy-duty truck. If you aren't comfortable wielding a torque wrench set to 250 ft-lbs for those massive front caliper brackets, don't risk it.
