"Perfect Pedal" G25 Hydraulic Brake Mod Review
Posted: Dec 7, 2009 3:34 PM Reply
Well, I've had almost a week now with the Perfect Pedal (
http://www.sim-sport.net/the_perfect_pedal.html), so I wanted to write up my thoughts on it. Overall, I'm very, very happy with it.
Background Info
The Perfect Pedal is a G25 brake pedal replacement that gives you a pressure sensitive brake pedal, but it's unique in that it uses a hydraulic system to generate the pressure (like a real car). You can buy the pedal and install it yourself, or you can send your pedals to Sim-Sport and have them perform the mod for you. I chose the latter, since my potentiometers needed replacing and I didn't feel like screwing them up
Aaron @ Sim-Sport performed the Perfect Pedal installation and potentiometer replacement on the same day that he received my pedals, and they were back in the mail heading my way the next day. One thing I wanted to be sure to mention is the packaging...I've never seen such a well protected shipment. I think I could have thrown the package off of my roof and my pedals would have been fine (see pic). The cables were also all neat and zip-tied, which I thought was a nice touch.
Anyway, I reassembled my pedals (I shipped them without the black plastic cover, to save shipping costs), and plugged my Bodnar cable in and I was good to go. All I had to do was recalibrate in iRacing, and everything worked great.
Thoughts
I've tried out a few load cell based pedal sets, so I knew the Perfect Pedal would be a big change compared to my G25 pedals. This is where the Perfect Pedal really surprised me...I was able to get up to speed a lot faster than I thought I would. The pedal just feels very natural, like I've been using a pressure sensitive pedal all my life. I think the natural feeling comes from how close this pedal feels to a real car.
I started with about 45 minutes worth of laps in the Mazda at Sebring, and got down to a 1:58.2, about .7 off of my PB. I've attached a screenshot of the laps from that session, which were honestly the first laps I did with the Perfect Pedal. You can see I spent the first half tweaking (and crashing...), then started to get more and more comfortable.
It's hard to describe, but as you build up brake pressure, the cylinder compresses very smoothly. "Squish" is the best word I can use to describe it, although squish normally has a negative connotation with braking systems. The squish factor lets you be very smooth and precise with your braking pressure, though, because the system builds pressure so progressively. It also releases pressure the same way, and I've found it much easier to trail brake and recover from a locked front tire with this pedal. When a tire locks, it's easier to release the brake force quickly because your foot doesn't have to travel very far like it would with a potentiometer based pedal.
To be honest, I was a little worried that switching to a pressure sensitive brake pedal would make me slower. With a potentiometer system, you have a definite hard stop at 100% brake force, but you don't have that with a pressure sensor. I thought that would make it harder to use the pressure sensitive brake, but it turns out not having a hard stop is actually liberating. Instead of thinking about how close I am to 100% brake or just hitting the stop at the end, I'm now braking based off of what the tires are telling me. Before, I'd smash down to 100% brake force in a lot of the straight line braking zones (depending on the car), when in reality, 70-90% brake force would have been better. It was just easier to hit the stop at the end. I'm finding it a lot easier now to use the optimal amount of brake force.
The only issue I've found is that if you haven't pushed the brake in a while, the first press isn't always smooth. I just make sure I push it once while on grid, and it feels good for the whole race distance.
Summary
I really couldn't be happier with this setup. I have better control under braking, plus it's nice to have a realistic brake pedal (I kinda thought realism and speed were going to be mutually exclusive). I've definitely gotten faster with this pedal, and it's made it easier to actually do the things I'm trying to do. More than that, it's reshaped my approach to braking, which I think has made a big difference for me.
I also can't say enough about Sim-Sport's customer service. I had a lot of questions about the pedal before I made my purchase, and Aaron answered them all quickly and completely. He asked what type of cars I drive in real life, and how I wanted the pedal to feel (you can adjust the feel based on how much fluid is in the hydraulic chamber). The standard pedal comes with 20 mL of fluid, but you can request up to 25 mL. Adding fluid increases the stiffness and decreases the pedal travel. If you want to tweak the fluid amount after delivery, Sim-Sport also sells an adjustment kit. I got mine with 20 mL, but might get the kit and try adding a little fluid later on.
I also wanted to mention that I drive at my desk, and the pedals don't slide with the stock G25 carpet grabber and the amount of pressure I'm using. You do have to let it dig in and take a set (as I found out entering turn 1 at Silverstone yesterday...), but after that, they're good.
Settings
So far, I'm using 588 as the left number during calibration, and 1.0 on the brake force curve. I might still try some new settings when I get the chance, and I'll update this post if I do.
Let me know if you guys have any specific questions, and I'll do my best to answer them.

I will get mine today can i se on track & Trace from UPS jubii yaaa
Florida - Denmark 5 dags and i got it
nice 👍
👍
. But I should be home tonight and will be able to test out the perfect pedal hopefully this week/weekend. I also just set up a room just for my Sim racing / gaming that I will show you guys.
