So the brakes in the kids buggy uses a remote slave cylinder kit to a hydroboost from a ford mustang. When the vehicle is running the brakes are decent, maybe al ittle tough to press but doable for a kid. But if you get in my buggy with the same master cylinder it is very easy to apply heavy brakes. So In prep for this years moab trip I wanted to trouble shoot this issue and see if I cant get it worked out.
The first tip that seems to be coming up is the pedal ratio. Right now I have probably 4-5 in from the pivot to the cylinder and then probably 10in after that to the bottom of the pedal. Apparently a 2-1 ratio isnt great so that maybe a good starting point. If I move the pivot 2-3in closer to the mc connection will that make enough of a difference.
Another thing I note is this, the pedal is dirrectly below the MC rod connector and also in line with the pivot at the frame. Where as with my other rig the pivot is back closer to the firewall then the pivot is out further and the pedal even further kinda like this /
SO with limited time to tweak and rework things and then be able to test them my questions are these...
1. If I just lower the pivot bracket closer to the mc a couple inches will that be enough to make significant change.
2. Is there a mechanical advantage to trying to get that top pivot point closer to the firewiall giving it more of / look.
