Possible seings with hard rubbers:
• 1x hard 19mm elastomer. This is the hardest setting. (A)
• 1x hard 28mm elastomer (B)
• 1x hard 37mm elastomer (C)
• 1x hard 19mm + 28mm = 47 elastomer (D)
• 1x hard 19mm + 37mm = 56mm (E)
• 1x hard 28mm + 37mm = 65 elastomer (F)
• 1x hard 19mm + 28mm + 37mm = 84 elastomer. This is the
default setting (G)
Possible seings with so rubbers:
• 1x soft 28mm + 37mm elastomer (X)
• 1x soft 19mm + 28mm + 37mm elastomer. This is the
softest setting. (Y)
All rubbers are marked ‘hard’ or ‘soft’ on the side of the
rubber. The hard elastomer can be used up to a load of 140kg.
The soft elastomer can be used up to a load of 100kg.
Do not build rubber stacks other than the 9 options outlined
above. Damage to the product may otherwise occur.
Do not mix hard and soft rubbers on one stack. We cannot
accurately predict the resistance behavior of mixed stacks.
Also, your stack will only be able to cope with the maximum
force of the softest rubber in the stack.
The brake pedal resistance is changed as follows:
1. Remove all preload on the rubber stack. First you need to
turn the lock nut towards the pedal arm, using the supplied
Brake - principle of operation
The Sim Pedals Ultimate+ brake pedal is force based. The
harder you press, the higher the signal output to the simulator
software will be. The force detection is lineair unless the
output curve is modified in SmartControl.
Your brake is equipped with a 2-stage system. Initially a metal
coil spring is compressed. This coil spring simulates the pad-
to-disc gap. The main loading of the brake disc is simulated
by compressing the rubbers.
By adjusting the brake pedal deadzone in SmartControl you
have the option to let the brake signal output start as soon
as you compress the metal coil spring, or only after the metal
coil spring has been fully compressed.
Brake - pedal resistance
The Sim Pedals Ultimate+ allow for a large range of settings
to set the resistance of your brake. This is done by varying the
total length of the elastomers in the brake rubber stack and/
or the hardness of the elastomer.
Please note that adjusting the resistance determines how
much pedal travel you will get for a fixed amount force
applied to the brake pedal. The total amount of force required
to get 100% pedal output in your simulator software is set in
the SmartControl software.
A total of 9 resistance settings are available.
