TrueBrake Logitech Brake Pedal Mod + Review by SRG

Barry Rowland of the Sim Racing Garage has released a new review, this time, he bring us the TrueBrake Logitech Brake Pedal Mod,  an upgrade for the for the Logitech G25/G27/G29/G920 brake pedal which gives the pedal a positive and realistic feel. It does this by emulating what a strain gauge load cell would achieve, you feel the load not the small pedal movements.

TrueBrake achieves this concept, fits perfectly in your Logitech pedal set and all at a reasonable cost. It is the most appropriate and cost effective brake pedal mod available for your Logitech brake pedal.

Some Official Features by AXC-SIM

TrueBrake achieves this by:

• Measuring the brake pedal load instead of the pedal position
• Increasing the load required to reach full braking
• Reducing the amount of brake pedal travel

What’s inside TrueBrake?

• Cylinder and body: CNC machined aluminium
• Piston: Has maximum of 4mm of travel inside the cylinder
• Main Spring: Heavy duty spring resists the movement of the piston
• Circlip: Retains the piston in the cylinder
• Linear Motion Potentiometer: High quality component that detects movement of the piston

3 Stage Load Curve:

1. When the brake pedal is pressed, the return spring compresses which in turn applies a small load on the TrueBrake piston.
2. As the brake pedal is pressed harder it engages with the polyurethane transition buffer and the load on the piston quickly increases.
3. The brake pedal is fully engaged with the TrueBrake piston and TrueBrake main spring.

The small movements of the TrueBrake piston are detected by the linear motion potentiometer which is connected in place of the stock Logitech potentiometer.

Brake Pedal Freeplay

TrueBrake is supplied with two different polyurethane buffers to give a choice of either 3mm (1/8”) or 6mm (1/4”) of brake pedal freeplay.

Engineering Quality

This unique and quality engineered solution has been rigorously tested and perfected.  All the components are housed in a 6061-T6 aluminium body and cylinder, CNC machined by AXC and designed to fit perfectly inside the Logitech pedal assembly. The end result is a robust and reliable pedal where the braking control is about pedal load rather than pedal travel. Just like a brake pedal should be!

Is TrueBrake a load cell?

We consider TrueBrake an “Electromechanical Load Cell” or a “Potentiometer Based Load Cell”.  Be clear that TrueBrake is not a Strain Gauge Load Cell. Strain Gauge Load Cells use an electrical strain gauge to measure the small bending of a spring element, which is often a metal beam. Using TrueBrake in your Logitech pedals gives similar end results as using a Strain Gauge Load Cell but at a much more affordable price.

Does TrueBrake measure load?

Yes.  The load compresses the internal heavy duty spring and that small movement is detected by the linear motion potentiometer.

Does a potentiometer measure load?

No. We would not claim that.

Does a potentiometer and a spring measure load?

When combined as a system, yes they do.  It’s basic high school level physics.

Can I return my TrueBrake if I don’t like it?

In the unlikely event that you are disappointed by your TrueBrake (within 30 days of you receiving it) you can return it for a refund.
