PEDAL BOX EXLPLAINED

ADJUSTABLE PEDAL FACES

  • Depth
  • Height
  • Pitch Angle
  • Without removing bolts

The PE Patented Pedal Box makes adjustments easy, providing you with a Pedal Box to suit your style. 
Simply loosen the pedal faces and explore your comfort by adjusting the depth, height and pitch angle of the pedal pads.
There is absolutely no need to remove bolts. 

Pedals are designed to be independent of the levers, so adjustments will not effect the mechanics (master cylinder integration or linkages). Featuring adjustable pedal geometry for feel and comfort, once the kit is installed in the desired location at your selected incline angle, the desired pedal face positions can easily be set using the inbuilt adjustment slots. The mechanical advantage can also be increased by raising the pedal faces up or decreased by lowering them down.

GAS/THROTTLE ADJUSTMENTS

Features inbuilt spring return and easy adjustment of the linkage geometry. Once installed, the linkage is easily adjusted to achieve the desired cable stroke. The cable stroke length is achieved via moving the adjustable rod along the slot in the cable linkage. Very fine settings can be achieved ranging from 30mm to 55mm stroke. The adjustable rod with rod ends allows fine motion ratios to be set to tune your gas throttle progression requirements. The gas / throttle pedal lever features an inbuilt stop in both directions. A permanent travel stop should be fitted to your vehicle on installation. The desired pedal face position can easily be set using the adjustment slots provided.

BALANCE BAR W/ REMOTE ADJUSTER

Remote brake bias adjustment. Our large 7/16″ balance bar operates on the principles of efficient force distribution to the front and rear master cylinders via pivoted lined bearings. The brake bias can be adjusted using the remote cable adjuster provided. If the remote cable adjuster is not desired, it can be replaced with locking nuts at your desired brake bias setting.

CLUTCH LEVER (MANUAL VERSION)

The clutch has an inbuilt lever stop high within the frame, minimising the risk of fouling by debris. The desired stroke or fluid displacement is easily adjusted to suit by selecting the appropriate cylinder bore and setting the push-rod length for adjusting the effective pedal stroke. The desired pedal face position can easily set using the inbuilt adjustment slots.

MECHANICAL ADVANTAGE

The challenge we set ourselves was to reduce the overall size of the pedal assembly. We worked on achieving equal fluid pressure & displacement to suit a wide range of motorsport disciplines. This physical size reduction would aid in further weight reduction, whilst allow fitting in tight spaces, and assist in clearing such items as steering columns.

HOW DOES A SMALLER PEDAL RATIO WORK?

The output fluid pressure & fluid displacement is no less than other high quality systems which utilise higher pedal ratios. How? The overall mechanical advantage is made up of several factors, mainly being mechanical advantage (the pedal ratio) & hydraulic advantage (the hydraulic ratio). The pedal ratio, pushrod efficiency, master cylinder travel & master cylinder bore all have an effect on the overall output fluid pressure & fluid displacement. This design uses a combination of reduced pedal ratio, and increased hydraulic ratio, the combined result is fluid pressure & displacement being equal to other high quality systems, just in a more compact way. We consider this a win/win. So pedal boxes with higher pedal ratios are not necessarily yielding a higher overall combined mechanical advantage or better efficiency. This is typically due to shorter stroke and larger master cylinder bores being used, ultimately the combined mechanical advantage remains unchanged.

BRAKE SYSTEM COMPONENT SELECTION

Our in-house dynamic simulation determines and optimises the suspension kinematics, aerodynamics, brake response, vehicle geometry & mechanical grip.
We can determine the ideal combination of master cylinders, rotors, calipers & brake pads to maximise the dynamic braking grip available, based on your specific vehicle characteristics.

BRAKE BALANCE

Initially there are several variables which, when understood enable you to refine your brake balance settings effectively.

The variables are, master cylinder bore sizes for front and rear, balance bar position, caliper selection (total piston bore areas) for front and rear, brake pad material & pad area, brake rotor diameter and thickness. All of these elements are important and the relationship between them is important to understand.

Consult a professional as necessary prior to committing to calipers, rotors and pads. Any homework done early in the design stage of your braking system will reduce any unnecessary expense.

Generally many vehicles transfer so much weight to the front under heavy braking, that as much as 80% of front braking effort is required, leaving 20% for the rear. Your particular vehicle may only transfer 65% to the front, so again, doing a little homework at the early design stages is vital to obtaining the correct brake components. Also, keep in mind the operating temperature of your braking system.

It is important that both front and rear brakes have the same temperature gradient at all times. This will ensure regular & predictable front to rear braking forces are present. A poorly designed braking system will lock the fronts at some times and lock the rears at others. This can typically be a result of incorrect operating temperatures relative to each other. Seek professional help as required.

MASTER CYLINDERS

The PE Pedal Box is designed to use smaller bore & long stroke masters than in many other quality systems.

Our design accepts "Girling Non-Integral Master Cylinders" , or Willwood's "Compact Remote Reservoir Master Cylinders" with 1.375" stroke. The Girling masters have 1.375" travel as opposed to 1.1" in many other quality systems. Our combination of longer stroke and smaller bore allows the pedal ratios to be reduced as a result, without compromising the overall mechanical advantage gained.

WHY NOT USE THE TRUNION PIVOTED STYLE CYLINDERS?

As our pushrod is designed to work extremely close to the master cylinder's axis, the need for a pivoting cylinder is eliminated. With other high quality systems, the pushrod angle is effected by pedal/lever positioning adjustments, but not in our case. With other systems, once pedal adjustments are made, the force/pressure curve can become parabolic in nature, this generally leads to irregular bias proportioning & poor brake pedal feel. Our pedal lever is designed to not effect the pushrod alignment when making pedal adjustments.

The pedal adjustments on the PE pedals are independent of the levers (all levers), thus eliminating pushrod deviation from the intended axis of travel. This design also provides for a very close to linear force/pressure curve, providing consistent bias proportioning & improved driver feel.

A variety of cylinder bore sizes are available (5/8”, 0.7” or 3/4” ). The pedal travel can be varied by pushrod length adjustments. The pedal levers can be adjusted for minimised stroke (shortening the pushrod) or to go to a maximum travel of 35° for increased travel, but care should be taken to ensure no binding occurs within the master cylinders at the higher pedal travels. Increasing pedal travel increases cylinder stroke improving an overall mechanical advantage on the clutch lever. Decreasing master cylinder bore sizes further increases the overall mechanical advantage for both clutch and brake levers.
