Diy Pedal Guide Parts
Building your own DIY Pedals - A Guide
You can start building your own DIY sim racing pedals using REAL pedal assemblies. You will need to first decide if you want a Floor mount or overhung pedals.

Find a pedal assembly that you like and can afford, spend as much as you can afford though as the pedals they will be doing most of the work.

Pedal Assembly
Pedals can be found on eBay searching Tilton Pedals, Racing Pedals, etc.

It would appear that you can then choose a pedal assembly that will fit into your sim racing rig. For example you may like the Tilton 72-603 pedals. They can also be found at Summit Racing and Jegs by searching “Pedal Assemblies”.

You will see 3 pedal sets and 2 pedal sets plus you can also find single pedal sets. All will work, and some will have a cheaper price tag in the total build cost. This usually comes down to budget, personal preference and space.

Master Cylinder
Master Cylinders pump the fluid and help give pressure to supply to the other parts of the system. The master cylinders you need will depend on what pedal brand you are going to use. Do the research and find what fits your pedal or pedal assembly.

What size bore to you use?
Several sim-racers have said that when making a pedal set that it really wouldn’t matter. You could use 7/8” bore Tilton 75 Series. The master cylinders come in a kit, which has a remote mount for the reservoirs. Again make sure you get the ones that match your pedal system.

Clutch Slave Cylinder
The Clutch slave cylinder is not going to go on your clutch, and if you just buy a single brake pedal you still need this very important piece of the system. This is what is going to give you the progressive feel of the braking. It would appear there are only two Clutch Slave cylinder that are recommended. These would be the Willwood brand or another one made by Howe Racing (which is cheaper). Choose the one you want, both have the same specs. These will work with any pedal assembly you pick.

Brake Lines
Choose how you want to run the lines, and how much line you want to use. 4x 10” pieces of Aeroquip hose should be fine. You will find there are several types of lines, if you find one that works for your system by all means get it. You will probably find TEFLON TAPE pretty handy.

Fittings
You are going to need several fittings to make this work and all tie in together. Again these come in all different prices so look around on Summit and Jegs to find the cheapest. AGAIN USE TEFLON.

2x -3AN male to 1/8" NPT fittings
2x 3/8-24 to -3AN Male

Pressure Transducer
Now we need to get data from the pressure we are producing by pressing the brake. What you will need is a 1600psi Transducer. These are the only ones known to work with a Leo Bodnar controller board, I also think these work with Derek Speare's circuit boards. You only need one of these.

High End Sim Racing Pedals
HEUSINKVELD ENGINEERING Sim Pedals

If you don't want to build your own pedals but you want what looks to be possibly the best high end pedals I've seen then you want to have a look at HE Sim Pedals. The main features of these high end pedals are:

No wearing potentiometers or sensitive hall sensors
Load cells on all 3 pedals for excellent durability and linearity with no moving parts
12 bit (4096 step) electronics (actual range depends on pedal travel and desired brake force)
Adjustable travel by independently adjustable ‘up’ and ‘down’ stops
Adjustable damping on all pedals
Greatly adjustable pedal feel and required effort
Adjustable pedal face ‘upright’ angle -3, 0 and 3 degrees
Adjustable pedal height in 5 steps for foot size 5 to 13
Solid individual cables from pedal to electronics box


Be aware, these pedals are not cheap.
