Specifically, the brake calipers on the 2019 Ram 1500 play a massive role in ensuring that this full-size truck can haul, tow, and stop with confidence. In this deep-dive, we’ll cover everything you need to know about the size of the brake calipers, their role in braking performance, comparisons across trims, maintenance tips, and why upgrading might be worth considering if you’re a serious truck owner.
For those in California looking to maintain or upgrade their truck, you can always rely on Simi Valley Chrysler Dodge Jeep Ram for OEM brake parts, service, and expert advice.
🔧 Brake Caliper Basics
Before we jump into the exact dimensions, let’s start with the basics.
A brake caliper is a clamping device that houses the brake pads and pistons. When you press the brake pedal, hydraulic pressure pushes the pistons, squeezing the pads against the rotors. This friction slows down and stops your vehicle.
On a heavy-duty vehicle like the Ram 1500, brake calipers need to be significantly larger and more robust than those found on sedans or compact SUVs. This ensures they can handle the extra stress from towing heavy loads, hauling cargo, and stopping a truck that weighs over 2,300 kg (5,100 lbs) before passengers, cargo, or trailers are even factored in.
📏 2019 Ram 1500 Brake Caliper Size
The 2019 Ram 1500 comes with a range of brake sizes depending on trim and wheel options. But across the lineup, Ram equipped the truck with some of the largest calipers in the half-ton class at the time.
- Front Brake Calipers:
The front brakes are the workhorses of any vehicle. On the 2019 Ram 1500, the front calipers are dual-piston calipers measuring approximately 60 mm (2.36 inches) per piston. This gives a combined clamping area large enough to handle aggressive braking and heavy towing situations. - Rear Brake Calipers:
The rear brakes feature single-piston floating calipers measuring about 45 mm (1.77 inches). While smaller than the front, they are still robust enough to provide stability under braking and keep the truck balanced, especially when loaded. - Rotor Pairing:
These calipers pair with massive brake rotors:- Front rotors: 13.8 inches in diameter
- Rear rotors: 14.1 inches in diameter (depending on trim and wheel size)
Put simply, the brake system on the 2019 Ram 1500 is bigger than many SUVs’ entire wheel sizes.
🚛 Why Size Matters on the Ram 1500
A large pickup like the Ram 1500 demands equally large brake calipers. Here’s why size is so important:
- Towing Power – The 2019 Ram 1500 can tow up to 12,750 lbs (when properly equipped). Large calipers provide the clamping force needed to bring a heavy trailer to a stop without overheating the system.
- Payload Capacity – With up to 2,300 lbs of payload, the truck needs calipers strong enough to handle stopping with the bed fully loaded.
- Heat Dissipation – Bigger calipers paired with vented rotors mean better heat management. Overheated brakes lead to fade, where the pedal feels soft and stopping distances increase.
- Longevity – Larger calipers spread braking forces more evenly, reducing wear on both pads and rotors, ensuring the truck remains reliable over the long haul.
⚙️ Variations Across Trims
The 2019 Ram 1500 was available in multiple trims — Tradesman, Big Horn, Laramie, Rebel, Limited, and more. While the brake caliper design remained largely consistent across trims, certain wheel and axle configurations came with slightly larger rotors and upgraded calipers.
- Standard Models (Tradesman, Big Horn): Dual-piston front calipers with 60 mm pistons, single-piston rears.
- Performance-Oriented Rebel: Reinforced components with stronger pads, same caliper dimensions but tuned for off-road conditions.
- Heavy Towing Packages: Some higher trims with Max Tow configurations used upgraded calipers with thicker pads and heat-resistant coatings for longevity under load.
Regardless of trim, the system was engineered for durability, with Ram engineering emphasizing consistent performance under heavy strain.
🔍 Comparing Ram 1500 Brakes to Competitors
To put things into perspective, let’s compare the 2019 Ram 1500 brake calipers to rivals:
- Ford F-150 (2019): Front calipers around 54 mm pistons, rear around 43 mm. Smaller overall, especially on base trims.
- Chevy Silverado 1500 (2019): Similar dual-piston fronts but smaller rear calipers than Ram.
- Toyota Tundra (2019): Comparable in the front, though older design meant less efficiency in cooling.
Verdict: The 2019 Ram 1500 had one of the most robust brake setups in its class, giving it an edge in stopping power and confidence.
