Hawk HB604B.598 HPS 5.0 Rear Brake Pads for BMW 135i 135is 2008-2013

Vehicle Fitment

• 2008-2013 BMW 135i Coupe (E82, 3.0L N54 / N55 Turbocharged I6, RWD) - Rear
• 2008-2013 BMW 135i Convertible (E88, 3.0L N54 / N55 Turbocharged I6, RWD) - Rear
• 2013 BMW 135is Coupe (E82, 3.0L N54 Turbocharged I6, RWD) - Rear

Fitment Notes

• Position: Rear axle only for all applications listed above.
• Not compatible with carbon ceramic rotors. For use with iron/metal rotors only.
• The BMW 135i used the N54 3.0L twin-turbocharged inline-6 from 2008 through the first half of 2011 production, transitioning to the N55 3.0L single-turbocharged inline-6 from mid-2011 (from 10/2010 production date) through 2013. The 135is retained the N54 engine throughout its single 2013 model year. Both engine variants share the same rear caliper and are fully covered by this pad.
• The 135i was produced as both a Coupe (E82) and Convertible (E88) - both body styles share the same rear caliper and are covered.
• The matching front pad for a complete 135i brake upgrade in HPS 5.0 compound is HB603B.616 (front, 6-piston caliper).
• HPS 5.0 delivers more stopping power and improved pedal feel versus OEM pads while remaining suitable for daily street driving. For track day or circuit competition use, higher-temperature compounds are available for this pad shape.

Features

• HPS 5.0 (High Performance Street 5.0) Ferro-Carbon compound - The next evolution of Hawk's HPS formula, delivering greater stopping power and improved rear brake pedal feel compared to the original HPS while maintaining street-appropriate noise, dust, and rotor wear characteristics - the compound of choice for 135i owners who drive daily and want improved rear braking over OEM pads without the cold-temperature limitations of race compounds.
• Decreased rear stopping distances - Delivers measurably shorter rear stopping distances from the 135i's rear caliper, contributing to improved overall braking balance and shorter total stopping distances alongside the front 6-piston system.
• Improved pedal feel from initial contact through the full stroke - The HPS 5.0 compound's progressive, linear friction profile provides consistent, informative rear brake response from the first application through full pressure, giving 135i drivers precise rear brake feedback for confident daily and spirited driving.
• Minimal fade under elevated temperatures - Withstands the sustained heat generated by aggressive street driving and light track sessions where OEM rear brake pads on the 135i platform approach their thermal limits, maintaining consistent rear performance through extended spirited use.
• High friction and torque hot or cold - Provides effective rear brake torque from ambient temperature through 750°F, making it immediately responsive from cold morning starts as well as during extended performance driving sessions.
• Gentle on rotors with extended pad and rotor life - The Ferro-Carbon formulation minimizes abrasive rear rotor wear, extending service intervals for both the pads and rear disc surfaces.
• Very quiet with low dust output - Engineered for near-silent, low-dust rear brake operation - preserving the premium daily-driver character expected of the BMW 135i without the noise and heavy dust accumulation of aggressive performance compounds.
• Smooth and predictable rear brake release - Delivers a clean, consistent rear brake release that supports stable chassis behavior and precise braking balance on the 135i's rear-wheel-drive platform.
• 100% asbestos, lead, chromium, cadmium, and antimony free - Manufactured in an ISO-certified facility to strict quality and environmental standards.

Product Description

The Hawk HB604B.598 HPS 5.0 rear brake pads are designed for the rear caliper of the BMW 135i (E82 Coupe and E88 Convertible, 2008-2013) and BMW 135is (E82, 2013). The 135i used the N54 3.0L twin-turbo inline-6 from 2008 through mid-2011 production, then transitioned to the N55 3.0L single-turbo from mid-2011 through 2013; the 135is retained the N54 for its single 2013 model year. Both engine variants share the same rear caliper and are fully covered. All 135i and 135is models are rear-wheel drive.

HPS 5.0 is the natural rear brake upgrade for 135i owners using this car as a daily driver. It delivers 20-40% more stopping power than OEM replacement rear pads, improves rear pedal feel across the full brake stroke, and resists fade through the extended hard braking demands of spirited street driving and occasional track visits - a meaningful improvement over the thermal limits of standard street replacement compounds in the 135i's rear system. The compound's Ferro-Carbon formulation operates quietly and produces low dust, maintaining the premium daily-driver refinement that 135i owners expect. For those who attend regular track days or circuit events where sustained high rear brake temperatures are generated, higher-temperature compounds in this pad shape provide race-level performance.

This pad is for the rear axle only. The matching front pad for a complete HPS 5.0 brake upgrade is HB603B.616. Compatible with iron and metal rotors only; carbon ceramic brake discs are not supported.
