This type of kit typically ranges from £600 - £1000+ for a front set. Availability is widespread through major automotive performance parts suppliers.

3. EBC Brakes Ultimax/Redstuff/Yellowstuff Range

EBC Brakes offers a tiered approach to brake upgrades, allowing you to choose pads and rotors that best suit your driving needs and budget.

Description:

EBC provides several pad compounds:

• Ultimax (OE replacement): Good for daily driving, quiet operation.
• Redstuff: A step up, offering reduced dust and improved performance with less initial bite but good stopping power.
• Yellowstuff: A more aggressive track-day pad with excellent initial bite and high-temperature performance, though it can produce more dust and noise.

They also offer paired GD series slotted and drilled rotors or BS series plain rotors to complement their pads. Using EBC components can significantly improve braking feel and endurance.

Part Numbers and Compatibility:

• For Veloster N (2019+): EBC part numbers are specific to the vehicle and component. For instance, front pads might be DP32181C (Redstuff) or DP42181R (Yellowstuff). Rotors could be GD2591 (GD series front pair).
• For Elantra N (2021+): Similar part numbering applies. Confirming the specific part number for your Elantra N is vital.

EBC pads and rotors are generally more budget-friendly, with pad sets ranging from £100 - £250+ and rotor pairs from £200 - £400+. They are readily available from numerous online retailers.

Beyond Kits: Other Essential Upgrades

While full kits are popular, you can also mix and match components or focus on other critical areas for braking improvement:

High-Performance Brake Pads

As mentioned with EBC, choosing the right brake pads is paramount. For spirited driving or track use, consider compounds from brands like Ferodo, Brembo, Hawk, or Carbotech. These offer superior heat resistance and friction coefficients compared to standard pads.

Braided Stainless Steel Brake Lines

Factory rubber brake lines can expand under pressure, leading to a softer pedal feel. Replacing them with braided stainless steel lines (often PTFE-lined) provides a firmer, more direct pedal response and improved modulation.

High-Temperature Brake Fluid

Brake fluid absorbs moisture over time, lowering its boiling point. Under heavy braking, this can lead to fluid vaporization and brake fade. Upgrading to a high-performance DOT 4 or DOT 5.1 fluid with a higher dry and wet boiling point (e.g., Castrol SRF, Motul RBF600) is a relatively inexpensive but highly effective upgrade.

What About Shims on a Veloster N?

When discussing brake upgrades, particularly brake pad changes, the topic of shim kits often arises. Shims are thin pieces of metal or composite material that fit between the brake pad backing plate and the caliper piston. Their primary purpose is to dampen vibrations that can cause brake noise, commonly known as brake squeal.

For the Veloster N, the need for specific aftermarket shims depends heavily on the type of brake pads you install and your sensitivity to noise. Performance-oriented pads, especially those with a more aggressive friction material, are sometimes more prone to causing squeal. If you're experiencing noise issues after installing new pads, or if you're fitting particularly aggressive pads, you might consider:

• OEM Shims: Check if your new performance pads come with integrated shims or if they are designed to use the original equipment (OE) shims from your Veloster N. Often, good quality aftermarket pads will include their own shims, or be designed to work with OE shims.
• Aftermarket Anti-Squeal Shims: Brands like Vibra-Tech or specific performance brake companies may offer universal or vehicle-specific anti-squeal shim kits. These are typically made from layered materials designed for maximum vibration absorption.

It’s crucial to ensure that any shims used are compatible with your chosen brake pads and calipers. Improperly fitted shims can negatively impact brake performance or cause component damage. If you're unsure, consulting with a professional mechanic or the brake pad manufacturer is recommended.
