brakes

Well, "details."

Power or manual and do you have a had pedal and is it sufficiently "off the floor" and just what DOES it do exactly? Have you for example played on maybe, a gravel road to see which end (if either) you can lock up?

Why do you claim "they used an improper master?"

And what parts were used to convert? There are many ways to do conversions, many
