    hi simmers

    just doing my normal rounds thinking for my sim. lol
    has anyone made a load cell brake using something like a motorbike brake system as it has the res built in and they can be brought very cheap a simple mod say for the lever make it stronger then put a short hydraulic pipe to the caliper and drop a load cell inbetween the pads of calliper. you could even tune it with various types of hard rubber instead of the pads to put the pressure on the load cell.

    am i thinking this might work ive not orderd any parts yet but have the brake set up.
    does this sound reasonable idea to try out and might work ??? or better still has anyone made it work.
    as i have to get some pedals for my dash soon to build up rather than the t500rs ones.


    this is what i mean for the lever mine is like that and its res is movable so you can place the lever parts at any angle or way and still keep the res in the right place. then a simple very short pipe to calliper and drop loadcell in that to be sqeezed, then maybe use rubber to soften the sqeeze ect... it might feel right as it uses the hydraulic system.

    hope to get some good feedback for this im very tempted.

    You might find the pressure is excessive when using an actual hydraulic caliper. It could end up crushing the load cell especially if you have your foot on the piston as opposed to using your hand to squeeze.
    If you can get the parts really cheap I'd still try it out, nothing wrong with experimentation and the experience with the process.

    You can also try bicycle hyd brakes.
    Cheaper and weaker.

    I was also thinking the pushbike brakes too but i am not sure a loadcell would fit as i don't have a load cell so as i have them both i could try either.
    its mainly about the idea and was hoping if it was far too much pressure can it not be fitted pressure control valve or like i was thinking some soft rubber that squashes aand gives abit so it not so hard on the loadcell.

    i will most likely order a loadcell next month it would be ace if it works.

    i was also thinking a bias brake adjuster valve to bring the pressure down to the caliper but brake pedal stay the same and have a hydraulic type feel to which i was hoping to get from this.
    ive found a 50kg loadcell on ebay thats £8.99 and is supposedly the same as the v2 pedals loadcell.
    it might be better i try and find one thats even higher kg for the job its being used for.
    does that sound better and do anyone know if theres one small enough with bigger force than 50kg

    As someone who rides bicycles a lot, most of which have hydraulic disc brakes, I would recommend against using the bicycle brakes. On bicycles, everything is made to be very lightweight, so they're not very strong. My brakes are designed to stop effectively with only one finger on the lever, so foot pressure would be well beyond their capacity. Also, I don't think they'd provide that "hydraulic feel" that you're after.

    That bias brake adjuster valve sounds like a good idea to reduce the pressure on the load cell if necessary. If you're near an auto wrecker, older vans and trucks (pre-4 wheel anti-lock brakes) often have a valve that controls pressure applied to the rear brakes based on suspension height. It's designed so that you get stronger rear brakes when you have a heavier load in the back. You could probably get one of them much cheaper than ordering a purpose designed valve, though the range of adjustment is a lot narrower.

    (P.S. If you want to experiment with bicycle brakes, there's about 10 mm of room between the pistons on the caliper that you could try to fit a load cell into. Some of the cheaper brakes have a piston on only one side, so you could modify them for additional clearance.)

    Its for the G27, but I found a spring that happened to be just the right length to slot in with the existing spring. So I can touch the pedal just a bit, but more brakes require more leg effort.
    Like its very stiff. Kinda a bit like some of the brakes in cars I have tested.
