Dodge Durango 2011-2023 Rear Stainless Steel Brake Lines

Firm Pedal, Zero Expansion: Stainless Steel Rear Brake Lines Built for the Dodge Durango

The Rotora L.58318 delivers a direct-fit stainless steel braided rear brake line upgrade for the 2011-2023 Dodge Durango, replacing factory rubber hoses that swell under pressure and degrade over time. The PTFE inner core resists fluid absorption and expansion at the molecular level, so brake pressure travels straight to the calipers instead of disappearing into hose flex. L.58318 is engineered to DOT Compliance and FMVSS 106 Standards, making it fully street-legal while delivering the pedal response you expect from a performance brake system.

If the threads are stripped (a common issue on these vehicles), chase them with an M10 x 1.0 die before installation. Die available here.

Key Features

• PTFE Inner Core: Virgin-grade Teflon inner tube resists expansion under pressure and will not degrade from prolonged brake fluid exposure
• Stainless Steel Braided Sheath: 304 stainless steel weave absorbs incidental impacts and resists road abrasion, corrosion, and saltwater exposure
• Blue PVC Outer Jacket: Abrasion-resistant PVC coating protects body panels, paint, and hose surfaces from chafing during suspension travel
• 3,500 PSI Tested: Every line is 100 percent tested in-house at 3,500 PSI before leaving the factory
• DOT and FMVSS 106 Compliant: Meets and exceeds federal motor vehicle safety standards for street-legal use
• Direct Bolt-On Fitment: Pre-formed to factory dimensions with all engineered fittings included, no cutting or flaring required
• M10 x 1.0 Banjo Fitting: Matches OEM thread specification; if stripped threads are present, chase with an M10 x 1.0 die before installation
• Strain Relief at End Fittings: Reinforced end fitting collars prevent stress cracking at the most vulnerable flex points
• Complete Hardware Kit: All fittings, clips, and mounting hardware are included

Vehicle Fitment

Note: Excludes all SRT 392, SRT, and SRT Hellcat trim levels. All SRT Durango models from 2018 onward are equipped with Brembo brakes at all four corners including the rear axle, which use different caliper banjo fittings and hose routing that is not compatible with L.58318. Contact us to confirm fitment for any SRT variant before ordering.

Frequently Asked Questions

Q: Will the Rotora L.58318 fit my SRT 392 or SRT Hellcat Durango?
A: No. All Dodge Durango SRT variants (SRT 392 from 2018, SRT Hellcat from 2021) come equipped with Brembo brakes at all four corners, including the rear axle. The Brembo rear caliper on these trims uses different banjo port geometry and hose routing than the standard rear caliper. L.58318 is not confirmed compatible with any Durango SRT equipped with Brembo rear calipers. If you own a Brembo-equipped SRT, contact us before ordering.

Q: How much will pedal feel improve after installing L.58318?
A: Most Durango owners report a noticeably firmer, more direct pedal after the swap. Factory rubber hoses expand slightly under hydraulic pressure, absorbing input that should be reaching the caliper pistons. The PTFE core in L.58318 has near-zero volumetric expansion, so fluid pressure transfers directly. The improvement is especially apparent during threshold braking or after repeated heavy stops.

Q: Is the Rotora L.58318 DOT compliant for street use?
A: Yes. L.58318 meets and exceeds DOT compliance requirements and is manufactured to FMVSS 106 (Federal Motor Vehicle Safety Standard 106), the federal standard governing hydraulic brake hose performance. It is fully legal for street, highway, and track use in the United States.

Q: How long does installation take?
A: Plan on one to two hours for a DIY installer with basic hand tools. The lines are direct bolt-on replacements that follow factory routing. The most common time variable is thread condition at the hard-line junction. If the threads are corroded or damaged (a documented issue on 2011-2017 Durangos exposed to road salt), chasing them with an M10 x 1.0 thread die before installation will save significant time and prevent fitting damage.

Q: Do I need to use an M10 x 1.0 thread die, and where do I get one?
A: Not always, but frequently on older or salt-belt Durangos. The hard line junction at the rear axle uses an M10 x 1.0 thread pitch. Corrosion at this point is a documented community issue on DurangoForum threads. Running an M10 x 1.0 metric die over the male fitting before threading the new banjo bolt prevents cross-threading, galling, and leaks. A standard M10 x 1.0 die is available at most auto parts stores and online. Order the exact die here.

Q: Will installation of these brake lines void my factory or aftermarket warranty?
A: No. Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your vehicle warranty solely because you installed an aftermarket part, unless they can prove the aftermarket part directly caused the failure in question. Rotora brake lines are DOT-compliant direct replacements and do not alter the OEM braking system in a way that would provide grounds for warranty denial.

Q: What brake fluid should I use, and how do I bleed the system after installation?
A: Use the brake fluid type specified in your Durango owner manual (DOT 3 or DOT 4 for most 2011-2023 models). The PTFE inner core of L.58318 is fully compatible with DOT 3, DOT 4, and DOT 5.1 fluids. After installation, bleed the rear brake circuit completely starting from the caliper furthest from the master cylinder. Follow the two-person or vacuum-bleed procedure described in the installation section below, and top off the master cylinder reservoir throughout the process.

Q: Is the Rotora L.58318 compatible with ABS and traction control systems?
A: Yes. L.58318 is a direct bolt-on replacement that operates within the existing hydraulic circuit. It does not modify ABS modulator connections, wheel speed sensor wiring, or the electronic stability control system. ABS, traction control, and Brake Assist remain fully functional after installation.

Q: Does the Pursuit or Special Service Durango use the same rear brake hose as the civilian R/T?
A: The 2018-2023 Durango Pursuit and 2012-2023 Special Service models use the same rear axle hose attachment points as civilian non-SRT variants. However, both police packages include an upgraded heavy-duty rear brake package. Verify the rear caliper part number on your specific unit before ordering. Contact us if you need help confirming fitment for a fleet or law enforcement vehicle.

Q: My Durango has a Brembo upgrade installed on a non-SRT trim. Will L.58318 fit?
A: Not necessarily. If a non-SRT trim has been retrofitted with Brembo or other aftermarket big brake calipers that use a different banjo bolt thread pitch or port angle, L.58318 may not fit without an adapter. Verify the banjo fitting thread pitch on your specific caliper before ordering. L.58318 is engineered for the stock rear caliper on non-SRT Durango trims.

Installation Instructions

1. Gather tools and supplies: Flare nut wrench set (metric), combination wrench set, ratchet and socket set, drain pan, brake fluid (DOT 3 or DOT 4 per owner manual), M10 x 1.0 metric thread die (recommended), brake parts cleaner, clean rags, and a turkey baster or fluid transfer pump for the master cylinder reservoir.
2. Prepare the vehicle: Park on a level surface, set the parking brake, and chock the front wheels. Raise the rear of the vehicle using a floor jack and secure on jack stands rated for the vehicle weight. Remove the rear wheels.
3. Protect the vehicle finish: Place clean rags or shop towels around the caliper and axle area to absorb brake fluid. Brake fluid strips paint on contact.
4. Locate the existing rear rubber hoses: On each side, trace the rubber brake hose from where it meets the hard line at the axle bracket to where it connects to the rear caliper banjo fitting.
5. Loosen the hard-line fitting: Using a flare nut wrench, break loose the hard line nut where it threads into the rubber hose bracket. Do not use an open-end wrench, which will round the nut.
6. Inspect and chase threads if needed: Before removing the old hose, visually inspect the male hard-line thread for corrosion or damage. If threads are compromised, run an M10 x 1.0 die over the fitting now, while it is still accessible. Clean debris with brake parts cleaner.
7. Remove the banjo bolt at the caliper: Using the appropriate wrench, remove the banjo bolt securing the rubber hose to the rear caliper. Note the position and number of copper crush washers on each side of the banjo fitting for reinstallation reference.
8. Remove the old rubber hose: Unthread the hard-line nut completely and remove the rubber hose from the axle bracket clip. Discard the old hose and crush washers.
9. Install the new Rotora L.58318 line: Route the stainless steel line following the same path as the factory hose. Confirm the line does not contact any moving suspension components, CV axle shafts, or sharp edges at any point in the suspension travel range.
10. Thread the hard-line fitting: Thread the hard-line nut into the new line's fitting by hand first, then snug with a flare nut wrench. Do not overtighten; standard torque for M10 x 1.0 brake line fittings is approximately 11-13 ft-lb.
11. Install the banjo bolt at the caliper: Install a new copper crush washer on each side of the banjo fitting. Thread the banjo bolt in by hand, confirm alignment, then torque to the factory specification for your year (typically 21-26 ft-lb on this platform). Reuse of crush washers is not recommended.
12. Secure the line in all factory clips and brackets: Reinstall any bracket clips, retaining clamps, or wire harness ties that hold the brake hose away from suspension components. Confirm there is no binding or excessive tension at full suspension droop and full compression.
13. Bleed the rear brake circuit: Top off the master cylinder reservoir before beginning. Starting with the rear caliper furthest from the master cylinder (typically passenger rear), attach a clear bleed hose to the bleeder screw and open it one-half turn. Have an assistant slowly depress the brake pedal to the floor, hold it, then close the bleeder screw before the pedal is released. Repeat until no air bubbles appear in the fluid stream. Move to the other rear caliper and repeat. Top off the reservoir throughout this process and never allow it to run dry.
14. Inspect for leaks: With the vehicle still on jack stands, have an assistant apply firm brake pressure and hold for 30 seconds while you visually inspect all new fitting connections for weeping or seepage. Address any leaks before the vehicle is lowered.
15. Reinstall wheels and road test: Reinstall wheels, lower the vehicle, and torque lug nuts to factory specification (130 ft-lb for most 2011-2023 Durango). Pump the brake pedal repeatedly before moving the vehicle until a firm pedal is achieved. Perform a low-speed test stop in a clear area before returning to normal driving.
