2003-2005 Dodge Neon Brake Upgrade Options

By Core Brake Parts Tech Team — Circleville, OH warehouse

For a 2003-2005 Dodge Neon SRT-4, the brake upgrade path runs in three steps: better pads and fresh fluid, stainless braided brake hoses for a firmer pedal, and then a front big brake kit if you track the car or have turned up the boost. Each step fixes a different problem, so match the upgrade to how you drive rather than jumping straight to the biggest calipers you can fit.

One note before you shop: the upgrade parts in this guide are built for the SRT-4 specifically. The standard Neon uses a different brake setup, so check that your car is an SRT-4 before ordering.

What the SRT-4 Came With From the Factory

The SRT-4 was a big step up from a regular Neon. TopSpeed lists the 2003 model with a turbocharged 2.4L four-cylinder rated at 205 hp and 245 lb-ft, a 5-speed manual, and four-wheel disc brakes with 11-inch front rotors, upgraded pads and larger calipers. It quotes 60-0 mph stops in under 120 feet on the standard brakes.

That is a solid street setup. The limits show up when owners add power, run sticky tires or take the car to an autocross or track day. The front brakes do most of the work on a front-drive car, and repeated hard stops from speed can overwhelm an 11-inch rotor with a single-piston sliding caliper. The result is fade, a long pedal and rotors that develop vibration.

Signs Your SRT-4 Has Outgrown Its Brakes

• The pedal sinks or feels soft after several hard stops, then firms up once things cool. That is heat-related fade in the pads or the fluid.
• Vibration in the steering wheel under braking after spirited driving, usually from uneven pad deposits on overheated rotors.
• A spongy pedal even when cold. Check for air in the system, old fluid and aging rubber hoses before blaming the calipers.
• Pads glazing or wearing fast after track days or autocross events.

Before upgrading, confirm the basics are healthy: calipers sliding freely, no leaks at the hoses or calipers, and pads with plenty of material left. An upgrade will not cure a seized slide pin.

Step 1: Pads, Rotors and Fluid

For a street-driven SRT-4 the most cost-effective upgrade is a performance pad on quality rotors, plus a full fluid flush. Brake fluid absorbs moisture as it ages, which lowers its boiling point, and boiled fluid is a common cause of a pedal that goes long during hard driving. Use the fluid type printed on your master cylinder reservoir cap and in the owner's manual.

Browse performance and replacement brake pads and brake rotors, and confirm fitment for the SRT-4 specifically, since its brakes differ from the base Neon.

Step 2: Stainless Steel Braided Brake Hoses

Factory rubber brake hoses swell slightly under pressure, and that swelling shows up as extra pedal travel. Stainless braided hoses resist that expansion. The Russell Performance stainless steel braided brake line kit 694310 is built for the 2003-2005 SRT-4. According to Modern Performance, the kit uses stainless braided hose with zinc-plated fittings, comes factory assembled, bolts on directly and meets the U.S. Department of Transportation MVSS-106 requirements for brake hoses.

This kit is made for the factory calipers. If you plan to install a big brake kit, read Step 3 first, because the Wilwood kit calls for its own line kit.

Hoses are a good job to pair with a fluid flush, since the system has to be bled anyway. See our full range of brake lines.

Step 3: A Front Big Brake Kit

If you track the car, run high boost or simply want the strongest stopping power, the next step is a big brake kit. The Wilwood Forged Dynapro 6 front big brake kit for the 2003-2005 SRT-4 replaces the factory front brakes with parts that Wilwood lists as follows:

• Calipers: forged billet Dynapro 6, six pistons, red powder coat, lug mount.
• Rotors: 12.19 inches in diameter and 0.81 inches wide, iron, 32 vanes, drilled and slotted with a black electro coat finish.
• Hats: aluminum short-offset big brake hats.
• Pads: Wilwood BP-10 compound.

Wilwood says the kit is engineered to stay compatible with the OE master cylinder output and factory ABS functions, so you do not need a new master cylinder. Two points to plan for:

• Wheels. Wilwood lists a 15-inch minimum wheel diameter and notes the kit may fit some 15-inch wheels. Check the wheel clearance diagram in the installation instructions before you buy.
• Brake lines. Wilwood states brake lines are not included and a separate Wilwood line kit is required.

The BP-10 pad is a sensible match for a street car that sees occasional hard use. Wilwood describes it as a medium friction, high performance street compound with gradual response, a low wear rate on iron rotors, and lower dust than standard replacement pads. It lists street, muscle car and drag racing use, and it notes the compound is NSF LeafMark certified and compliant with SAE J2975.

What to Replace at the Same Time

• Brake fluid, with a complete bleed of all four corners after any hose or caliper work.
• Rear pads and hardware, so the rear brakes are in good shape to share the work. Our brake hardware kits cover clips and pins.
• Front wheel bearings and tie rod ends are worth a quick check while the front end is apart on a high-mileage car.

How Hard Is the Job?

A pad, rotor and fluid job is a straightforward home project. Braided hoses add a little work: you need flare nut wrenches, new crush washers where the hose bolts to the caliper, and a full bleed. A big brake kit is a moderate job that includes mounting brackets, setting up hats and rotors and bleeding new calipers. Follow Wilwood's installation instructions, torque every fastener to the values given there or in the factory service manual, and bed the new pads before hard use. If you are not comfortable working on brakes, have a shop do the big brake kit.

Frequently Asked Questions

Do these upgrades fit a regular Dodge Neon?

No. The Wilwood kit and the Russell line kit in this guide are listed for the 2003-2005 Neon SRT-4. The standard Neon uses different brakes.

Will a big brake kit work with my ABS?

Wilwood says this kit is engineered to maintain compatibility with the OE master cylinder output and factory ABS functions.

Can I keep my stock wheels?

Wilwood lists a 15-inch minimum wheel diameter and asks you to check the clearance diagram before purchase, because not every 15-inch wheel clears.

Do I need new brake lines with the Wilwood kit?

Yes. Wilwood states brake lines are not included with the kit and a separate line kit is required.

Are braided hoses street legal?

The Russell SRT-4 kit is described as meeting the U.S. DOT MVSS-106 brake hose requirements.
