Last Friday,

My friend and I went to lunch and I offered him to drive. Being about 6-1 (I'm 5-9) he ajusted the seat back. When checking up his setup by pressing on the pedals, the seat slider jumped a few notches back until reaching the back pad. So I checked out various positions of the seat and it does the same thing when the seat is completely moved foreward. I guess I'm lucky that towards the middle (my setup) it locks well.

I haven't dismanteled the seat rails to examine the situattion, but has anyone been through this situation?

Recommendations?

Thank you

Take the seat rail apart and look at the little square blocks that lock to the track. Take a grinder and bevel them to make the edge that locks taper upward toward the rail. It will make the slider lock into the seat track the more you push the seat backwards.

I have also seen some people use a seat track lock on both sides, with a bar between them to use as a release.
