Product Description

The EBC S13KR1528 rear brake kit is a fully matched upgrade for Lexus GS, IS, and RC series vehicles from 2013 through 2020. It combines high-performance Yellowstuff GG-rated aramid pads with precision-engineered 310 mm vented RK rotors, coated in Thermic Black anti-rust protection.

Installation is bolt-on and straightforward - no modifications are required. The pads come pre-shimmed, chamfered, and coated with EBC's Brake-In® treatment to ensure fast bedding and reduced noise. Rotors are balanced and run-out tested for smooth operation. The included caliper lube packet helps maintain proper slide-pin action. Maintaining the Thermic Black coating is essential to preserve the warranty.

Fitment confirmed through model year 2020 using verified Lexus-specific references; coverage beyond 2020 remains unconfirmed at the time of listing. Ideal for drivers seeking enhanced braking performance while retaining OEM fitment. Pair with a front Yellowstuff/RK kit for full-system balance.
