Product Details
Master cylinder braces are a common upgrade to reduce brake booster / master cylinder deflection under sudden, hard braking conditions. This deflection occurs due to the thin firewall material that the brake booster bolts to actually flexing under sudden, hard braking. Our ECS Tuning Master Cylinder Brace was designed and engineered in-house to reduce this deflection which improves brake pedal response while adding confidence in your brake's hydraulic system. Our design requires no permanent modifications to the body or battery tray.
PART DESIGN
Designed and engineered in-house using state of the art 3D laser scanning and CAD technology for precision fitment
Manufactured from 10 ga. cold rolled steel for superior structural strength in the limited space around the master cylinder and battery tray
Powdercoated in a tough wrinkle black finish for corrosion protection
Bolt-on battery tray bracket picks up an additional mounting point on top of the battery tray for added strength
Utilizes the closest chassis mounting points under the battery tray
Sandwiches between the battery tray and battery tray mount. This will lift the battery tray roughly 3.5mm without adverse affects.
KIT CONTENTS
Master Cylinder Brace, adjustment screw, jam nut and swivel foot
Battery Tray Bracket and Button Head Screws
PERFORMANCE FEATURES
Immediate pedal response can be felt thanks to the reduction in master cylinder / brake booster movement. This translates to improved pedal feedback and easier modulation due to the predicative behavior in the hydraulic system. We measured 58% reduction in master cylinder deflection on initial brake pedal travel.
PRODUCT DEVELOPMENT
Our ECS MK5/MK6 Master Cylinder Brace was designed, engineered, tested and quality inspected by our Research and Development team in our Wadsworth, Ohio facility. We strive for the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long term product testing
