BRAKE KIT FOR MERCEDES-BENZ W124 500E / E500

Complete Trophy Kit – Calipers, Rotors, Pads, Lines, Brackets, Hardware – New, Never Mounted

Offered is a brand-new StopTech Trophy Big Brake Kit engineered specifically for the legendary Mercedes-Benz W124 E500/500E (124.036). Designed to dramatically increase braking performance beyond the stock R129-sourced factory setup, this kit includes every component required for installation, with all parts never mounted and in unused condition.

To accommodate this upgrade, the seller notes that 18-inch wheels are required for clearance due to the significant increase in rotor diameter and caliper size.

Kit Contents

This StopTech Trophy package includes:

• (2) StopTech Trophy 6-piston calipers

• (2) Two-piece StopTech AeroRotors – 355x32mm slotted

• (2) Hard-anodized 6061-T6 billet caliper brackets w/ stainless studs

• (4) StopTech performance street brake pads

• (2) Upgraded stainless steel braided brake lines

• All required mounting hardware and fasteners

Every component is in new, unused condition, ready for installation.

Fitment Details

This kit was designed for the W124.036 E500/500E, which originally utilized R129 500SL/SL500 front brakes. Early 500E models came with 300x28mm rotors, while mid-1993+ examples received 320x30mm rotors. This StopTech kit steps up dramatically to 355x32mm two-piece floating rotors.

The kit also fits the W124.034 400E/E420 which shares the same hub, knuckle, and steering arm as the 500E. For 400E/E420 fitment, the splash shield must be replaced with the equivalent R129 part to ensure proper clearance.

StopTech AeroRotor Technology

StopTech’s patented AeroRotor system uses directional vanes that widen toward the trailing edge to draw more air into the disc. This improves cooling efficiency by pushing significantly more airflow through the rotor, resulting in:

• Higher resistance to heat-soak

• Reduced brake fade

• Improved heat dissipation

• Lower stress on bearings and steering knuckle

• Longer rotor and pad life

The two-piece design reduces unsprung weight, resists warping, and allows thermal expansion without wheel-bearing heat transfer.

Caliper Brackets & Stainless Brake Lines

Included are hard-anodized billet 6061-T6 caliper brackets engineered for the 500E/400E hub geometry. Stainless studs provide high-strength mounting and corrosion resistance.

Upgraded stainless braided StopTech lines replace OEM rubber hoses, creating a more consistent brake feel by preventing line expansion under heavy heat and pressure. This upgrade eliminates soft pedal issues during performance driving or repeated high-speed braking.

A system flush with high-temperature DOT4 fluid is strongly recommended when installing this kit.

Included Performance Brake Pads

The kit includes StopTech low-dust, high-heat performance street pads. Characteristics:

• Strong initial bite (“snappy” pedal feel high in the stroke)

• Stable friction properties under heavy heat

• Low dust output

• Suitable for spirited driving and light track use

These pads are well-matched to the Trophy system for balanced street and performance operation.

Condition Summary

• All items are new, never installed

• Complete StopTech Trophy big brake kit

• No damage, wear, modifications, or mounting marks

• Suitable for stock ABS system and factory master cylinder

• Requires 18-inch wheels for caliper clearance

This is a premium, high-performance brake upgrade for one of Mercedes’ most iconic super-sedans, engineered for road, canyon, and light track use without compromising reliability or daily drivability.
