COMPATIBILITY2022+ Toyota GR Corolla (LHD Only) INTRODUCTION The Radium Engineering brake master cylinder brace installs on the strut tower and provides the needed support and immediate response for hard braking. The billet aluminum design is lightweight yet very stiff. Because it is a 1-piece design, there are no unwanted secondary flexing. Furthermore, it utilizes 3 mounting points that promote reinforcement. Physically, the brace is very streamline supporting aftermarket modifications mounted near the strut tower. The strategically selected adjustment screw prevents damage to the master cylinder housing with the use of a large diameter aluminum head. The included stainless steel jam nut prohibits any potential slippage of the set preload.  HOW IT WORKS When the brake pedal is depressed, not all the mechanical energy is transferred into hydraulic brake line pressure. Unfortunately some of the energy is wasted flexing the thin firewall. With the Radium Engineering master cylinder brace, firewall flexing is eliminated allowing all of the brake pedal input force to be applied for stopping the vehicle. This enables a firmer pedal feel and more responsive brake system. FEATURES-CNC machined from 6061 aluminum-Solid 1-piece design for increased rigidity-Black Type-II anodized and laser engraved-Aluminum preload adjustment bolt (will not harm the aluminum MC)-Stainless steel jam nut-Stainless steel bolts INSTALLATION Using factory mounting threads, installation very quick and easy. This brace does not require any cutting, drilling, or modifications to the vehicle.  Instruction PDF
