Tilton Floor Mount – Aluminum – 2 & 3 pedal (98-1209) - Manual (Page 2)

master cylInder mountIng
Tilton 600-Series Pedal Assemblies are designed to accept Tilton master cylinders.
Secure the master cylinders to the pedal frame with the provided serrated flange nuts.
Master cylinder pushrods may be too long for some applications and may have to be short-
ened to obtain correct pedal position (see Pedal Positioning & Adjustments). If you need
to shorten the pushrod, chamfer the end of the threads after cutting for easy adjustment
(threading) of pushrod length.
Attach the hydraulic lines to the master cylinders.
The brake system is gravity fed. Mounting the reservoirs above the caliper level is important
to maintaining a firm pedal, and is more reliable than using a residual pressure valve. Locate
your reservoirs accordingly. Detailed instructions are included with each TB&C master
cylinder.
Detailed bleeding instructions are included with every Tilton master cylinder kit. As with
any balance bar system, always bleed a front and rear caliper at the same time to allow full
master cylinder stroke.
throttle lInkage (P/n 72-603 only)
An extension for attaching a throttle cable to the pedal is provided, as shown in Diagram 2.
Modify the end to accept your particular cable or linkage. There are five extension mounting
positions on the throttle pedal to provide a wide range of motion ratios.
In general, keep the extension as short as possible while maintaining proper clearance for
the foot and leg. A longer extension places a larger twisting load on the pedal and does not
allow the movement to be as free.
For a throttle connection system in the front of the pedal, please see Tilton's optional
throttle linkage system, P/N 72-791 (Shown installed in Diagram 3).
Pedal PosItIonIng & adjustments
The proper pedal positioning is highly dependent on the driver preferences. The position of
the brake and clutch pedals is set by adjusting the length of the master cylinder pushrods.
The position of the throttle pedal is set by adjusting the stop screws (if applicable). Ensure
the pushrods engage at least ½” (12mm) into the clevises. In short, set pedal position so that
the driver is comfortable and safe.
Pedal Ratios - The pedal ratios on this assembly can be adjusted by moving the foot pad
position. For available ratios, please see the foot pad position chart laser-etched onto the
front of the brake pedal (Diagram 4).
Brake Pedal - With the system properly bled, and the pedal depressed, the pedal should be
vertical or leaning slightly towards the driver. The driver should not be stretching their toes
to reach this pedal position, and their knees should be slightly bent. Keep in mind, as the
race progresses, any problems with pad knock back or fade will only increase the distance
the pedal must travel. Tighten the pushrod jam nuts after the pedal positioning is set.
Throttle Pedal (P/N 72-603 only) - A good starting point for the throttle pedal position is to
have it even with the brake pedal in the depressed (full throttle) position. This allows a driver
who is completing their braking maneuver with the right foot, to make a quick change back
to the throttle. Some drivers prefer the throttle to be slightly closer to them. Set the throttle
stops accordingly and tighten the jam nuts.
With the throttle linkage attached, adjust the throttle stop so that the engine throttle fully
opens without straining the cable or linkage. The positive stop must stop pedal movement,
not the linkage, which could bend or break.
Clutch Pedal - The position of the clutch pedal is mostly a matter of driver preference. Adjust
the pedal position accordingly and tighten the pushrod jam nuts.
Most racing clutch and release bearings require the use of a positive stop on the clutch
pedal. Setting this stop properly will prevent damage to the clutch and allow the clutch to
release cleanly. The clutch stop setting is usually 1/4" – 3/8” (6.4mm – 9.5mm) past the point
of clean clutch disengagement, measured at the foot pad.
