The PERRIN Master Cylinder Brace locks down the master cylinder preventing unwanted movement due to a weak firewall. Allowing the driver to regain maximum braking force and increased pedal stiffness.
The thin sheet metal firewall isn’t able to deal with the constant forces from repeatedly applying the brakes in all conditions. Over time it begins to flex and give as the brake pedal is depressed. The PERRIN Master Cylinder Brace creates a bridge between the firewall, master cylinder, and shock tower, eliminating flex in the firewall while braking.
Stiffen Up Your Brake Pedal Feel
The PERRIN Master Cylinder Brace eliminates the flex at the firewall, so you feel nothing but solid pedal feedback with every application of the brakes. Even slowing for a stop sign, the difference can immediately be felt after installation of the PERRIN Master Cylinder Brace.
When possible we try to design Master Cylinder Braces in one piece to improve rigidity. The PERRIN Master Cylinder Brace for the 2002-2007 WRX & 2004-2007 STI are CNC machined from a large piece of 6061-T6 billet aluminum for extreme stiffness. With stainless steel hardware and an anodized finish, the PERRIN Master Cylinder Brace will look great and last the life of the car, even in the harshest conditions.
The PERRIN Master Cylinder Brace is designed to attach strategically to multiple points on the shock tower. This helps reduce flex in the brake master cylinder by creating a solid connection between it and the chassis. To further aid in stiffening or tightening up this connection, included is an adjustable screw that allows tension to be preloaded on the master cylinder.
Anodized black with a vivid PERRIN logo, the PERRIN Master Cylinder Brace for 2002-2007 WRX & 2004-2007 STI are guaranteed to continue looking great while being used.
