Product Description

The PERRIN Master Cylinder Brace stops the master cylinder from moving inadvertently, increasing the firmness and responsiveness of the brake pedal.

Your brake pedal is connected to the thin sheet metal firewall which flexes as you apply the brakes. The firewall is not stiff enough to deal with the constant and repeated forces while applying the brakes. The PERRIN Master Cylinder Brace creates a bridge between the firewall, master cylinder, and shock tower, significantly reducing flex in the firewall while braking. The PERRIN Master Cylinder Brace significantly reduces flex at the firewall, so you get a solid brake pedal feel with every application of the brakes. This is very noticeable while under heavy braking and even slowing for a stop sign. The difference can immediately be felt after installation.

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. The PERRIN Master Cylinder Brace is constructed of CNC Machined 6061 aluminum, and CNC formed Steel. This combination of different materials is used to add extra support compared to other systems. Making this from two CNC parts instead of a series of welded steel pieces keeps the part extremely stiff as well as very light. The aluminum portion of the PERRIN Master Cylinder Brace is anodized black with a bold PERRIN logo laser engraved into the upper surface. The steel section is wrinkled powder coated in your choice of red or black to match your other PERRIN parts. Perfectly combines an aesthetic improvement to your engine bay as well as a braking feel.
