Hi folks,

Not sure if this is the ideal spot but it's brakes, so here it is. Has anyone else been frustrated by how the brake boost kicks in seemingly randomly, and when you're normal braking the pedal travel is significant before it engages?

It's really frustrating. My TH is only 4 months old and since day 1 the brake pedal has tons of travel before it engages, but, if you tap it quickly or hard, or for no reason at all, the brake boost kicks in and gives you instant pedal response. I LOVE THIS. When it does kick in, the brakes are so much easier to control and modulate and predict, and is significantly safer and allows better response time and softer modulation.

For those that have the diag tools, I'm considering one to get rid of the stupid seat belt charm becaue I can't even drive around my own property without it driving me insane. But, has anyone looked into if you can set the brake boost, or how much regenerative braking can be adjusted? Does anyone have any recommendations for diag tool for this task?

Thanks!
