braking is a skill you just have to practice. Find a place on a trail that goes down rather steeply, or even a road somewhere. Now, using only your front brake, ,see how how can control your speed using ONLY the front brake.

If you are endo -ing... you are doing panic grabs. There are sitations where you do not want to front brake of course!! ( like drops, gullies) but even then you can use it and be gentle. Trying using just one or two fingers on the front brake and not your whole hand. They can be adjusted also to not be so grabby.
