The Brief
The owner wanted to improve braking feel and performance without going to a full big brake kit. The car sees regular track days alongside daily use, so the goal was a real step up in pedal feel, fade resistance, and stopping power while keeping the factory calipers.
The Build
All four corners were done. Endless MX72 pads went in front and rear for strong initial bite and proven high-temp performance on the 86/BRZ platform. HEL Performance braided lines replaced the factory rubber items to eliminate flex under pressure, and a full bleed and flush with Endless RF650 fluid raises the boiling point, which is critical for pedal feel during hard track use.
The Hardrace master cylinder stopper was bolted to the firewall behind the brake booster to brace the master cylinder under heavy pedal pressure and take up the play in the factory mount for a tighter initial response. Everything was bedded in following the pad manufacturer’s procedure to ensure proper transfer layer from day one.
The Result
Pedal feel is firmer and more immediate, with less dead travel before the brakes start working. The MX72 pads deliver strong initial bite on the street and hold up through repeated hard stops on track without the fade the factory pads are known for. Combined with the RF650 fluid, the pedal stays firm even after sustained use in hot conditions.
