Wilwood Under Dash “Super Pedal” Dual MC Brake Pedal Assembly – Forged

PN: 340-12509


Under Dash Reverse Swing Forged Super Pedal Dual Master Cylinder Conversion Kit

This is the best solution available for strong braking power without using any kind of brake assist such as a vacuum power booster or the very ugly hydro boost system. By using 2 small manual race quality master cylinders this Wilwood pedal creates line pressures equal to or greater than assisted systems. You also gain tremendous brake “feel” and the safety of never losing your brakes because of engine failure. Each master is sized and dedicated to either the front or rear circuit. The front MC is a .875″ bore unit while the rear circuit uses a 1.00″ bore MC. This system is compatible with single or multiple piston calipers of all designs. They are adjustable for front/rear bias by adjusting with the patented Wilwood balance bar system. This is a very simple under dash, pedal mounted, adjuster. The attractive aluminum high volume master cylinders protrude only 5″ and are quite narrow. They come with bail release black aluminum tops. Remote fill plastic rez master cylinders available above. If your dash top does not come off you need remote fill! The entire 2.2 (sans MC’s) lb pedal assembly is fully anodized in Wilwood’s new Platinum-E color.

This is a fantastic solution for those looking to:


  • Mount brakes entirely under the dash
  • Upgrade their braking to a race quality system that does not require power assist
  • Replace their OE pedal with a lighter (only 2.2 lbs) adjustable aluminum unit
  • Easily add a hydraulic clutch MC
  • Improve the overall appearance of this often ugly equipment
  • Non slip removable pad are included

Pedal mounts to firewall (vertical wall) and under dash (horizontal bracket). The master cylinders will be under your dash. You will need a removable hatch to service MC’s or order the remote fill reservoirs above. Remote MC options are: standard Combo Remote, Compact Remote with plastic reservoirs or Compact Remote with Billet Remote reservoir style MC’s. Look at the thumbnails for pics and measurements. You will need to create some brackets to mount this under your dash. The pedal has 4 horizontal “ears” with bolt holes that are easily mounted to with angle iron etc. The pedal is made of very sturdy anodized aluminum and finished with a racy look. The pedal comes with removable non slip pads. Pedal ratio is a 6.25:1 good for tight spaces.

Pedal arm is 11.71″ long. Mounted total length is 12.00″ long. See drawing for more measurements.
