GrimmSpeed Master Cylinder Brace – 2003-2006 Mitsubishi Evo 8/9

GrimmSpeed Master Cylinder Brace , 2003-2006 Mitsubishi Lancer Evolution VIII/IX

The GrimmSpeed Master Cylinder Brace for the 2003-2006 Mitsubishi Lancer Evolution VIII/IX braces the brake master cylinder against the firewall, reducing the flex that occurs in the brake pedal feel under hard braking. Without a master cylinder brace, the master cylinder can move slightly under hard pedal pressure , this movement is felt as a soft or spongy sensation in the pedal that does not correspond to air in the brake lines.

DETAILS

• Braces master cylinder against firewall
• Reduces pedal flex under hard braking
• Improves brake pedal firmness and feel
• Bolt-on installation , no permanent modification
• Includes hardware
• Fitment: 2003-2006 Mitsubishi Lancer Evolution VIII/IX

The brake master cylinder on the 2003-2006 Mitsubishi Lancer Evolution VIII/IX is bolted to the firewall at a single point. Under hard pedal pressure , particularly in performance driving or emergency braking , the master cylinder flexes forward slightly against the brake pedal push. This flex is transmitted back through the pedal as a soft feeling that many drivers interpret as insufficient braking power. The GrimmSpeed master cylinder brace creates a second bracing point that eliminates this flex.

The improvement in pedal feel is immediate and measurable , the brake pedal feels firmer and more direct with the brace installed, and the threshold where the driver detects the car’s actual braking limit becomes more accessible. Installation is bolt-on using existing mounting points with no permanent modification to the firewall or firewall components.
